Rating of the best pumps for cars, the best pump manufacturers

Cooling system pump design

Pump (pump) of the engine cooling system Structurally, the pump is a classic centrifugal pump for pumping water and non-aggressive liquids. It consists of the following parts:

• Sealed housing. It has a complex shape and is most often made of aluminum alloys. For connection to the system, two pipes are made in the housing - suction and pressure. The first is connected to the line coming from the radiator, and the second to the line of the engine cooling jacket.
• Shaft – transmits rotation from the drive to the pump impeller.
• Impeller or impeller. It has specially shaped blades with which it pumps coolant into the system.
• Drive pulley.
• Seals (oil seals) – prevent leakage of coolant at the points where the pump is attached to the lines.
• Bearings.

The pump is located in the engine cooling system between the radiator and the jacket. Most often this is the front part of the engine.

Initially, simply purified water was used as a coolant, and therefore such a pump is often called an engine water cooling pump. Now this term is irrelevant, since not pure water is used for cooling, but aqueous solutions with corrosion inhibitors (in warm climates) and antifreeze (in winter), which also contain ethylene glycol.

Signs of a pump malfunction

Sooner or later, problems arise with the pump and the unit fails. This may be due to both the high mileage of the car and the installation of a low-quality product. Therefore, it is worth considering what malfunctions may occur with the pump and what to do in this or that case.

Oil seal leak

It is quite easy to detect coolant leakage through the oil seal: a puddle usually appears under the car. If the sealing element is damaged, for example, as a result of wear, antifreeze will get to the pump bearing, as a result of which the lubricant will be washed out of the device, and the part itself will soon collapse. To prevent this from happening, it is necessary to periodically inspect the car and eliminate possible problems.

If the oil seal fails, antifreeze leaks from the pump.

Appearance of noise

If extraneous noise is heard from the pump area while the engine is running, this indicates an imminent breakdown of the unit. The most likely cause of noise is failure of the bearings or weak fastening of the impeller. In any case, the part needs to be dismantled, subsequently damaged, repaired or replaced.

Decreased performance

Whatever antifreeze is used in the cooling system, it is a chemical substance. Over time, erosion occurs in the pump housing or impeller, which can lead to a decrease in the flow of pumped liquid. As a result, the motor may overheat with all the ensuing consequences. Therefore, if the coolant temperature sensor on the instrument panel begins to exceed +90˚С (operating temperature), it is worth thinking about a possible replacement of the pump or, at least, a revision of this unit.

Increased vibration

If increased vibration comes from the pump area, first of all you need to inspect the pump housing in the bearing area: sometimes cracks may appear on it. It would also be useful to check the correct installation of the generator belt, pump pulley and fan. If faulty parts are found, replace them.

Dirty coolant

If the coolant has not been changed for a long time, problems may arise with the pump. It is not difficult to determine if the system is dirty: the color of the liquid will be brownish instead of red, blue or green. If the antifreeze turns black, most likely oil has entered the cooling system.

Dirty antifreeze indicates the need to replace it

How to check the pump's performance

You can check the functioning of the pump yourself. To do this you will need:

1. Warm up the engine to operating temperature and clamp the upper pipe leading to the radiator. If you feel a surge in pressure when you release it, then the pump is working normally.
2. There is a drain hole on the pump so you should pay attention to it. If the oil seal does not cope with its functions, then antifreeze may protrude from this hole.
3. While the engine is running, you need to listen to extraneous sounds. If a hum is heard from the pump, then most likely the bearing has become unusable. You can check it with the engine turned off by shaking the pump pulley. If play is felt, it means the bearing needs to be replaced.

Work on checking the pump with the engine running should be carried out carefully, not forgetting about the rotating fan and high coolant temperature.

Circles of circulation

Installation and installation of the oil pump VAZ 2108-2109-21099 The cooling system in the car has two circulation circles: large and small. The small one is considered the main one, since when the unit is started, coolant immediately begins to circulate through it. In the operation of the small circle, only the channels of the cylinder block, the pump, and the interior heating radiator are involved. Circulation takes place in a small circle until the internal combustion engine reaches normal operating temperature, after which the thermostat activates and opens the large circle. Thanks to this system, engine warm-up is significantly reduced, and in winter, the system does not so much cool the unit as maintain its normal temperature regime.

Small and large coolant circulation circles

The operation of the large circle involves a fan, a cooling radiator, inlet and outlet channels, a thermostat, an expansion barrel, as well as those elements that take part in the functioning of the small circle. The outer circle, also known as the large circle, begins to work when the coolant temperature reaches 80-90°C and ensures its cooling.

Luzar

Russian manufacturer operating on the basis of the Ukrainian Lugansk Automobile Radiator Plant. It produces pumps and other spare parts for the VAZ 2114 and other car models. The products are distinguished by acceptable quality and low prices. It is sold in many physical and online stores. Available in all regions of the country.

The manufacturer claims a guarantee of 125,000 kilometers. But products do not always serve as expected. The percentage of defects is high. Pumps may not be designed for heavy use.

Pros:

• Acceptable quality;
• Prevalence;
• Large declared resource;
• Low prices.

Minuses:

• Not suitable for active use;
• Marriage occurs.

The cost is about 1700 rubles.

Operating principle of the engine cooling pump

Location of the cooling system pump The main task of the cooling system pump is to create excess pressure to ensure forced circulation of fluid in the circuits. On the practical side, this speeds up the process of heat exchange between engine components and coolant.

When the car engine starts, the pump drive transmits rotational motion to the impeller through a belt drive and shaft. At this moment, a vacuum is created at the inlet (suction pipe), which facilitates the absorption of liquid into the pump. The liquid is in a cooled state, as it comes from the radiator of the cooling system.

Entering the central part of the pump, the liquid moves along the impeller blades and, under the influence of centrifugal force, is forced through the outlet pipe into the jacket of the engine cooling system (to the cylinder head). Under the influence of high pressure, the coolant passes through the circuit through the main components and removes heat. After this, it returns to the radiator again, where it cools and is sucked in by the pump for a new cooling cycle.

What should be inside. And what does the original look like?

Open the box. You can buy a pump that will necessarily come with a cork gasket . Not cardboard! Previously, these pumps came with quality certificates. Since the summer of 2015, TZA has not included these certifications with pumps.

Now the TZA marking is on the impeller, the logo is embossed . There is a laser dot application on the pulley . The part number is stamped and matches the number on the packaging. Logo and QR code. And there is another nuance: if you are careful, you will notice that numbers are stamped on the case. This is called unification and standardization. It's just a body, it's the same for all front-wheel drive models. Instead of indicating 2108, as it was before, now 2170 is indicated here, or, let’s say, 2108. The case is exactly the same.

Let's look at two original pumps, old and new. There is one more nuance about the housing: on the original pump there are holes on the impeller . We turn the pump; there is a plug on the body that serves as a stopper. On fakes there is also this hole, but there is no stopper for the pump shaft bearing. Another feature is the casting of this very case . On TZA this casting is porous and clearly visible . And the new fakes, which are sold in new packages, also do not have a bearing roller stopper, although the pump looks exactly the same.

In general, be careful, don’t be fooled! Buy only high-quality parts and then your car will work properly for a long time.

How does a water pump work?

Cooling system liquid pump repair

The purpose of pumping equipment is to deliver liquid to the point of water collection. Regardless of the design features, the principle of operation of the water pump is the same. When the electric motor is turned on, a vacuum is created in the working chamber. Low pressure inside the housing promotes the suction of water, which moves to the outlet pipe. The outlet pressure has a force sufficient to overcome the hydraulic resistance of the pipeline.

The type of unit and the design of the working body determine the features of its operation.

Centrifugal pump

Centrifugal-type units are characterized by a combination of high performance and pressure. Optimal performance characteristics ensured their popularity among consumers. What does a centrifugal water pump consist of:

• body made of durable material - steel, brass, bronze, cast iron;
• a rotor rotated by an electric motor;
• impeller with blades (impeller);
• branch pipes – inlet and pressure.

Centrifugal pump device

The rotating blades of the impeller create centrifugal force inside the housing. The liquid is drawn in, pressed against the walls of the chamber, and then pushed out into the pipeline under pressure. The universal type of equipment is distinguished by a wide variety of models. The units are classified:

• by installation method - submersible, semi-submersible and surface;
• in the direction of the shaft - horizontal and vertical;
• by the number of impellers (stages) - single-stage, multi-stage.

Advantages of centrifugal type devices:

1. Operates at temperatures up to +350.
2. Durability and long service life.
3. High efficiency.
4. Affordable price.

For organizing water supply and irrigation, console-type models are recommended. They are designed for pumping liquids with impurities. Multi-stage installations will ensure high productivity and uninterrupted water supply. Cantilever structures require protection from external influences, so they are placed indoors.

Vortex pumps

Thanks to its design features, the equipment is capable of creating powerful pressure. How does a vortex type water pump work? When rotating, the impeller blades form a vortex of the pumped liquid. This property makes it possible to provide high pressure with small installation dimensions. Compact models are used for irrigating gardens and vegetable gardens. They are not sensitive to air bubbles entering the liquid, but quickly fail when mechanical impurities enter the water.

Vortex mechanism

Advantages of vortex units:

1. Compact size.
2. High pressure, installation pressure exceeds that of centrifugal models by 3-5 times.
3. The simplicity of the design facilitates maintenance and repair.
4. The equipment is capable of self-priming liquid.

Disadvantages include low efficiency (about 45%) and sensitivity to abrasive particles.

Vibration pumps

Vibrating-type units are used to organize irrigation and water supply of private farms and cottages from an individual source. The equipment is unpretentious in operation and can be used when pumping contaminated liquids. The operation of the device is associated with the influence of a magnetic field on a coil with a core. The metal core is connected to a flexible diaphragm which, when flexed, creates low pressure in the suction chamber. The liquid enters the housing, and when the core and diaphragm return to their initial position, it is pushed out through the outlet pipe.

Vibration units

Advantages of vibration units:

1. The ability to pump contaminated water, which is used when pumping wells and boreholes.
2. Affordable cost of equipment.
3. The absence of rubbing parts increases the service life.

Vibration pumps are not without their disadvantages:

1. Sensitivity to voltage changes.
2. Destructive effects of vibration on well walls.

The choice of pump should be approached responsibly, taking into account its reliability and consumer characteristics. The main criteria for choosing equipment: pressure, productivity, sensitivity to contamination and power consumption. The unit should be purchased taking into account the operating conditions and purpose, then it will last the maximum period.

Choosing a pump for the VAZ-2114

When purchasing a water pump it is very important:

1. Carefully inspect the part and assess the condition of the metal and all connections.
2. It is advisable to compare several options to see the difference. In general, low-quality products are immediately noticeable.
3. Next, it is important to pay attention to checking the blades and the angle on the side where the pump is attached to the engine block.
4. There are four pump options: Gates, Luzar, TZA and HEPU. Luzar and TZA are in great demand among car enthusiasts. They have a long service life, are silent and durable. TZA are sold with a cork gasket, so they are more popular. When purchasing, it is advisable to check with the seller the characteristics of all types of pumps, and make your choice based on this. If you are not well versed, then ask the seller for advice, be sure to name the make of your car, and then he will select the appropriate option for you. You need to purchase only in specialized stores, where all parts have a guarantee.

What to look for when buying a water pump

The water pump (pump) is an important element of the cooling system, necessary for the circulation of antifreeze within the system. Pump malfunctions can lead to boiling of the motor. To avoid sad consequences, you should approach the choice of components responsibly. Let's consider several criteria by which it is easy to determine a high-quality water pump.

Impeller

The impeller is an actuator that pumps antifreeze. Particular attention should be paid to the material from which this element is made.

Plastic impeller. Most modern components are equipped with a plastic impeller. It has less weight compared to metal counterparts, and, accordingly, has lower inertia. This allows the engine to spend less energy spinning the impeller. Thin blades deliver liquid efficiently. Often this design is closed.

“Fucking basin. "

Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.

Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not a new one, on credit is unreasonable. My salary is 24k a month, so collecting 600-700 thousand is almost impossible for me. I started looking for different ways to make money on the Internet. You can’t imagine how many scams there are, what I haven’t tried: sports betting, network marketing, and even the volcano casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that I could make money was currency trading on the stock exchange, they call it Forex. But when I started delving into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, studying trading strategies. I tried it on a demo account, then opened a real account. To be honest, I didn’t manage to start earning money right away, until I understood all the mechanics of options, I lost about 3,000 rubles, but as it turned out, it was a precious experience. Now I earn 5-7 thousand rubles a day. I managed to get the car buy after half a year, but in my opinion this is a good result, and it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone)) If If you want to change your life like me, then here’s what I advise you to do right now: 1. Register on the site 2. Practice on a Demo account (it’s free). 3. As soon as you get something on the Demo account, top up your REAL ACCOUNT and go to REAL MONEY! I also advise you to download the application to your phone, it’s much more convenient to work from your phone. Download here.

Malfunctions of the VAZ pump The causes of breakdowns can be various, for example, the formation of play or jamming of the bearing. It is not uncommon for the impeller to start spinning freely, but separately from the shaft. If the pump is leaking or making noise, then it also needs to be replaced.

Service life of a VAZ pump Much depends on the quality of the pump. For example, a defective or low-quality pump can work for only 10 thousand km. If the pump lasted more than 100 thousand km, then it is generally accepted that there was a high-quality pump. From the factory, VAZs are equipped with TZA pumps, which have a long service life.

How to distinguish a fake? The pump must be in a high-quality box, inside it is a warranty card with the date of manufacture and stamps and a gasket. There is a holographic sticker on the pump.

Which pump is better to choose?

Below is a rating of the most popular water pumps among car owners in the domestic automobile industry. The list includes the best-selling pumps across the country and is compiled based on recommendations from experts and auto repair mechanics. Each brand will have a short description outlining its advantages and disadvantages so that everyone can determine what is best for them.

FENOX

The list begins with a very well-known company in certain circles. Under the name of this brand, a large number of various spare parts for VAZ cars, both classic models and more modern ones, are manufactured. When choosing a water pump for a new Niva or a classic, most people in the know will point to the Phenox.

The company has large production capacities in many CIS countries and is focused on producing parts specifically for the domestic auto industry. Therefore, pumps, and other equipment of the brand, meet the requirements of manufacturers and the required quality.

Since last year, pumps from this company have not been widely used due to their low cost and short service life. However, if you put in some effort, you can find a pump, and with moderate driving in LADAs it will last quite a long time.

One of the disadvantages is the large number of fakes on them. In addition, sometimes marriage occurs.

METELLI

Next on the list is a company with production facilities primarily located in Poland. Manufactures and distributes automobile pumps both as replacement units and parts mounted during vehicle assembly. Due to the high quality of their products, they are often purchased by auto industry giants like Ferrari, Fiat and Peugeot, and put their logos on them.

All units undergo strict quality control and are tested for reliability, meeting the international standard ISO 9002, which is a guarantee of durable and reliable operation. In addition, there are almost completely no counterfeits of METELLI on the market, since all devices are ordered through an official dealer or trusted suppliers. The company's pumps are perfect for Kalina or a similar model, tested and reliable. Recommended for installation on VAZ Kalina, Priora, Granta, Vesta with a 16-valve engine and on VAZ 2110, 2114 with an 8-valve engine.

Reviews from car enthusiasts who have become Metelli clients are mostly positive.

The main drawback is the lack of price lists for some brands of cars.

The majority of car owners agree that the best pumps for the VAZ 2107 are manufactured by DOLZ. In addition, the company’s assortment includes a huge variety of pumps for any car, both domestic and foreign.

The company has been operating for over 80 years and has long established itself as a reliable and trusted supplier of automotive components. The manufacturer concentrated on the manufacture and distribution of pumping equipment for passenger cars and trucks, which provided them with the ability to make only high-quality units.

A narrow focus in production made it possible to provide 95% of European cars with pumps. At the same time, create only high-quality products. The company was able to achieve such success thanks to patented technologies. Impellers made of special alloys are resistant to abrasion and cavitation wear, which eliminates the negative consequences of using low-quality antifreeze or water in the cooling system.

There is only one drawback that should be highlighted, namely the high cost.

He is a representative of a Swiss company specializing in the production of auto components. It has a large number of production sites and facilities throughout Europe and the CIS. When buying products from this brand, you should not focus on the country where the product was produced; strict quality control ensures the reliability of all products, regardless of the place where they were produced.

The brand's products are very popular among domestic car owners due to their high quality and relatively low cost. An excellent option for VAZ 2114 or similar cars. According to users, the pump can not be changed up to a mileage of 130,000 km, which is 20 - 30% more than similar ones.

However, due to their great popularity and widespread availability in markets, pumps are often counterfeited. Therefore, when choosing a pump, you need to be careful and careful. Company representatives point out that the original products have the mark of the assembly shop on the body and markings on the packaging. If at least one of these elements is missing, you should refrain from purchasing. Recommended for installation on VAZ Kalina, Priora, Granta, Vesta with a 16 valve engine.

Among the disadvantages, as mentioned above, is a large number of fakes. However, by following the manufacturers' recommendations when choosing, you can avoid purchasing counterfeits.

Replacing the Fluid Pump

After you have purchased a new pump for the VAZ 2114 (which is better - mentioned above), you should install it. For this you will need:

1. Turn off the engine (if the machine is running) and wait until the system cools completely.
2. Disconnect the terminals from the battery and remove the drive belts.
3. Drain the liquid from the system using a plug bolt (before doing this, remove the cap from the expansion tank).
4. Remove the timing belt by first unscrewing the bolts on the protective cover and removing it. (Important! After the belt is removed, it is strictly forbidden to manually turn the crankshaft or camshaft).
5. Remove the old pump (sometimes dismantling it may require some effort, since the original pump is additionally fixed with sealant).
6. Degrease the surface after sealant (for example, acetone).
7. Install the new pump and reassemble in reverse order.

By performing these simple operations, you can quickly install a new pump and return the car's cooling system to normal operation.

Any car parts can deteriorate over time. Despite the fact that the water pump is a durable and reliable device, it can also become unusable. As you know, nothing lasts forever, so over time the pump needs to be changed or repaired. In case of serious damage, it is advisable to replace the pump with a new one, which will serve properly for many years. It is very important to purchase a high-quality and durable part.

The best pumps for a car

The choice of which pump to install will depend on logistics, in particular. However, there are a number of manufacturers that are ubiquitous, and their products are used by the majority of domestic car enthusiasts. The following is a list compiled solely on reviews and tests of individual car pumps found on the Internet. The rating does not advertise any of the brands listed in it.

Metelli

The Italian company Metelli SpA produces a wide variety of auto parts, including car pumps. The products of this company are sold in more than 90 countries around the world, which indicates their high quality. Pumps are supplied both to the secondary market (as a replacement for failed units) and as original ones (installed on machines off the assembly line). All of the company's products comply with the international quality standard ISO 9002. Currently, the company's main production facilities are located in Poland. It is interesting that many auto parts, including pumps, produced under the brands of such well-known automakers as Peugeot, GM, Ferrari, Fiat, Iveco, Maseratti and others are produced by Metelli. Therefore, their quality is high. In addition, it is noted that products of this brand are rarely counterfeited. But it still makes sense to pay attention to the quality of packaging and other precautions.

Reviews from car owners and mechanics who have used Metelli pumps are mostly positive. There is a virtual absence of defects, very good processing of the metal of the impeller, and durability of the device. In addition to the pump, the original kit also includes a gasket.

A significant advantage of Metalli car pumps is their relatively low price with very good workmanship. Thus, the cheapest pump as of the beginning of 2019 costs about 1,100 rubles.

DOLZ

The Dolz trademark belongs to the Spanish company Dolz SA, which has been operating since 1934. The company specializes exclusively in the production of automobile pumps for cooling systems, both for cars and trucks, as well as for special equipment. Naturally, with such a targeted approach, the company produces extremely high-quality spare parts under its own brand. The Dols company was one of the first to start producing aluminum pumps, which not only reduced the weight of this unit, but also made the cooling system more technologically advanced.

The company's products cover up to 98% of the European automaker market and are also exported overseas. In particular, the products have a Q1 Quality Award and are used for cars manufactured by Ford. Quite often, Dolz products can be packaged in boxes from other packaging companies. So if you have such information, you can buy a high-quality car pump even cheaper.

The reliability of Dolz water pumps is especially distinguished by the quality of the impeller. This is ensured by the use of special aluminum casting and mechanized assembly. An additional advantage is that they are practically not counterfeited. Thus, the originals are sold in branded packaging marked TecDoc, and at the same time its geometry is perfectly respected. If there is a fake on sale, it will cost little money, while the original Dolz pumps are quite expensive. This is their indirect disadvantage, although their service life offsets it.

The price of the cheapest pump of the mentioned brand as of the above period is about 1000 rubles (for a classic Zhiguli).

SKF

SKF is originally from Sweden. It produces a wide variety of products, including water pumps. However, the company's production facilities are located in many countries around the world, in particular, Ukraine, China, the Russian Federation, Japan, Mexico, South Africa, India and some European countries. Accordingly, the country of origin may be indicated on the packaging differently.

Hepu

The Hepu water pump is often chosen by owners of the VAZ 2114 and other Zhiguli models. The manufacturer has its own research center. It studies the properties of metals. Therefore, our own developments are used to produce products. The parts of this brand are known for their good quality. They are designed more for moderate loads than active ones. Products often last at least 90,000 kilometers. But sometimes there are defective spare parts on sale. Pros:

• Reliability;
• Own developments;
• Prevalence;
• Affordable price.

Minuses:

• Marriage occurs.

The cost is about 1700 rubles.
