Impeller pump is a device that is equipped with a flexible working element. Models are used for pumping liquids with increased viscosity. Also pumps are often used for pumping. To date, various models are actively used in pharmaceutical, perfumery, dairy, canning and other fields.

The devices can also work with thick liquids, however, in this situation, a lot depends on the engine power. If we consider the advantages of specifically impeller modifications, then this is primarily a wide range of applications. It is also worth noting that pumps can be used as dispensers. They are ideal for pumping emulsions. However, the liquid may contain various small particles.

Pump device

An impeller pump without a motor is an impeller. It is connected to the transition shaft. At the end of it is a special head. There are different types of blowers for pumps. For fluid suctionseparate hole. Guides in the device are installed in the main chamber. The diffuser itself is most often of a flat type. In some cases, the body is made with a shirt.

How to DIY?

It is quite difficult to make an impeller pump with your own hands. In this case, you will need a large chamber for pumping fluid. The impeller itself must be sized for the outlet. The shaft for the standard model is available with a diameter of at least 2.5 cm. In this situation, it is more expedient to use a steel supercharger. A pipe is required to suck up liquid. Diffusers are mainly used flat.

They are installed above the impeller. In this case, the impeller should be located next to the blower in the pump chamber. The nominal flow of this type of device must be maintained at the level of 3 cu. meters per hour. Directly, the engines are most often installed at 15 kW. The system must withstand pressure of 10 meters.

This impeller pump (12 volts) is equipped with a cylindrical chamber. In this case, there is a shirt to protect the body. The direct transition shaft of the model is provided by 2.7 cm. The supercharger is used from steel. The head of the shaft has teeth. If we talk about the parameters, then the specified model weighs exactly 13 kg. The nominal feed rate is at the level of 3 cu. meters per hour. It is also important to mention that the feed parameter is 12 meters. The motor in this pumpthe asynchronous type is used, and its power is 18 kW.

Devices "NSU-3/0, 75"

This impeller pump is actively used in the perfumery field. Its device is very similar to the modification NSU-3 / 0, 35. The pumps are able to work with liquids of different viscosities. The camera of the model is installed of a cylindrical type. The supercharger in this case is located behind the impeller. The impeller itself is used with small guides. The adapter shaft is exactly 2.5 cm in diameter. Its head is made with teeth, and is able to withstand heavy loads. The model has an asynchronous engine, and its power reaches 20 kW. The voltage of this impeller pump "NSU" can withstand 220 V at an operating frequency of 45 Hz.

Dairy models

Dairy pumps are usually made with oblong chambers. Engines on them are often installed collector type. Superchargers, in turn, are steel. Transition shafts are used directly with a small diameter. Dairy products require high RPM models. If we talk about power, then on average it fluctuates around 20 kW. The nominal feed rate is 4 cu. meters per hour. The kinematic viscosity of this type of device is maintained at 210 cSt.

Devices for fat and oil products

High power pumps are used for oil and fat products. Cameras for them are used only with shirts. At the same time, the levelnoise in this case should not exceed 65 dB. If we talk about the design features of the models, then the impellers deserve attention. Their guides are of short length, but they withstand large loads.

The impeller is installed directly in the chamber. The adapter shafts of the models are quite different in diameter. Motors can most often be found asynchronous type with a power of 15 watts. The head pressure of the devices reaches 11 meters. The nominal flow parameter, in turn, does not exceed 6 cubic meters. meters per hour.

Features of models for the production of confectionery

For the production of confectionery products, pumps are selected with a large kinetic viscosity parameter. In this case, the transfer temperature should be at least 80 degrees. If you pay attention to the design features of the devices, then you should mention the power of the engines. On average, this parameter fluctuates around 22 kW. The cameras themselves are cylindrical in shape.

Adapter shafts are used with a diameter of 2.1 cm. Superchargers are most often installed behind the diffuser. The heads of the models are available with cloves. Guides, as a rule, are of small length. The indicator of the nominal flow of pumps is at the level of 4 cubic meters. meters per hour. In this case, the pressure parameter is not more than 13 meters. Suction nozzles are available in different diameters.

Pumps for fruits and vegetables

Impeller pump for fruits and vegetablesrequired with large suction port. The devices must operate at a temperature of at least 70 degrees. Engines on models, as a rule, are installed with a collector type with a power of 15 kW. They work from a network with a voltage of 220 V and an operating frequency of 55 Hz.

The transition shafts they use are short. Thus, the nominal feed rate of the devices is insignificant. However, the pressure parameter is on average 12 meters. It is also important to note that the impellers are installed directly in the chamber. To date, there are many modifications with shirts on the market. Their average noise level is 60 dB.

Pumps in the cosmetic industry

The ointment impeller pump is compact. A powerful engine is not required in this case. Adapter shafts for models are installed with a small diameter. Superchargers are most often used steel. The impellers themselves are mostly flat. Impellers in pumps are used with guides. If we talk about the parameters of devices, it is important to mention the power, which in some models does not even reach 12 kW. The pressure indicator, in turn, is no more than 8 meters.

Perfume production models

For the manufacture of perfumes, the impeller pump is usually used with low power. In this case, the motors must be of the collector type. They work from a network with a voltage of 220 V, and their operating frequency is 53 Hz. Directlyadapter shafts are used with a diameter of about 2.5 cm. In terms of the size of the suction pipes, the models are quite different. In this situation, much depends on the volume of the main chamber. Superchargers are often made of steel. Guides for such devices are only suitable for flat ones.

The diffuser in many models is located at the wheel itself. If we talk about the parameters of the pumps, it is important to mention the nominal flow. On average, this indicator does not exceed 3 cubic meters. meters per hour. However, there are more powerful models. In this case, the pressure parameter lies within 12 meters. The pumping temperature of the pumps is allowed a maximum of 70 degrees. The kinetic viscosity must be at least 230 cSt.

Pumps in the pharmaceutical industry

For pharmaceuticals, the shape of the impeller is very important. In this case, the guides should be at least 1.2 cm thick. All this will allow you to pump liquid with small particles without problems. The kinematic viscosity parameter should lie in the region of 210 cSt. At the same time, the nominal supply is welcomed not lower than 4 cubic meters. meters per hour. Additionally, the pressure indicator is taken into account. On average, it is 12 meters. However, if we consider modifications with collector motors of 10 kW, then in this situation for pumps this parameter will reach up to 14 meters.

Pumps for the production of household chemicals

For the production of household chemicals, an impeller pump with collector motors is excellent. The limiting frequency in this case should not exceed 50 Hz. If we talk aboutdesign features of the models, it is important to note that transition shafts are allowed with a diameter of at least 2.6 m. This ensures good pressure. Also noteworthy is the supercharger. In these configurations, it is installed behind the diffuser.

Directly, the impellers in diameter may differ. On average, the nominal feed rate is 4 cubic meters. meters per hour. The motors in this case have a power of at least 12 kW. For liquid, the maximum temperature is allowed at 75 degrees. Many models are made with shirts by manufacturers.

Models for working with petroleum products

For pumping oil products, pumps can be found in a wide variety. First of all, it is important to mention compact models, the power of which does not exceed 10 kW. In this case, transition shafts are installed with a diameter of less than 2.2 cm. Short chambers are used directly. Shirts for them are installed quite rarely.

On average, the nominal supply of devices is at the level of 4.5 cubic meters. meters per hour. The pressure indicator does not exceed 11 meters. These pumps have short guides. Therefore, the limit frequency setting can reach 60Hz.
