An impeller pump is a device that is equipped with a flexible working element. Models are used for pumping liquids with high viscosity. Also, pumps are often used for pumping. To date, various models are actively used in the pharmaceutical, perfumery, dairy, canning and other fields.
Devices can also work with thick liquids, but in this situation a lot depends on 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 the pumps can be used as dispensers. They are ideal for pumping emulsions. Moreover, various small particles may be contained in the liquid.
Pump device
An impeller pump without an engine is an impeller. It connects to the adapter shaft. At the end of it is a special head. Pump superchargers are of various types. A separate opening is provided for fluid suction. Guides in the device are installed in the main camera. Directly the diffuser most often has a flat type. In some cases, the body is made with a shirt.
How to do it yourself?
Making an impeller pump with your own hands is quite difficult. In this case, you need a large chamber for pumping fluid. The impeller itself must be sized to fit the outlet. A shaft for the standard model is available with a diameter of at least 2.5 cm. In this situation, a supercharger is more appropriate to use a steel one. A suction pipe will be required to absorb fluid. Diffusers are mainly used flat.
They are installed above the impeller. In this case, the impeller should be near the supercharger in the pump chamber. Nominal delivery of a device of this type must be maintained at a level of 3 cu meters per hour. Engines are directly installed most often on 15 kW. The pressure system must withstand 10 meters.

Direct transition shafts are used with a small diameter. For dairy products, models with high RPM are required. If we talk about power, then on average it fluctuates around 20 kW. The nominal flow rate in this case is 4 cubic meters. meters per hour. The kinematic viscosity of a device of this type is maintained at 210 cSt.
Devices for oil and fat products
For oil and fat products, high power pumps are used. Cameras for them are used only with shirts. In this case, the noise level in this case should not exceed 65 dB. If we talk about the design features of the models, impellers deserve attention. Their guides are used for short lengths, but they withstand large loads.
The impeller is mounted directly in the chamber. Adapter shafts of the models are quite different in diameter. Motors most often can be found asynchronous type with a power level of 15 watts. The pressure head 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 pumping temperature should be provided at least 80 degrees. If you pay attention to the design features of the devices, 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. Blowers are most often installed behind the diffuser. The heads of the models are available with teeth. Guides, as a rule, are of small length. The rated flow rate of the pumps is 4 cubic meters. meters per hour. In this case, the pressure parameter is not more than 13 meters. Suction nozzles are used in various diameters.
Pumps for fruits and vegetables
For fruits and vegetables, an impeller pump is required with a large suction pipe. Devices must operate at a temperature of at least 70 degrees. Engines on models are usually installed in the collector type with a power of 15 kW. They work from a network with a voltage of 220 V and an operating frequency at around 55 Hz.
Adapter shafts are used short. Thus, the nominal feed rate of the devices is negligible. However, the pressure parameter averages 12 meters. It is also important to note that the impellers are mounted directly in the chamber. Today on the market there are many modifications with shirts. The noise level on average is 60 dB.
Cosmetic Pumps
The ointment impeller pump is compact. A powerful engine in this case is not required. Adapter shafts for models are installed with a small diameter. Superchargers are most often used steel. Impellers themselves are mostly flat. Impellers in pumps are used with guides. If we talk about the parameters of the 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.
Models for the production of perfumes
For the manufacture of perfumes, an impeller pump, as a rule, uses a small capacity. In this case, the motors must be of the collector type. They work from a network with a voltage of 220 V, and their working frequency is 53 Hz. Directly transitional shafts are used with a diameter of about 2.5 cm. Models are quite different in size of suction nozzles. In this situation, a lot depends on the volume of the main camera. Superchargers are often made of steel. Guides for such devices are suitable only flat.
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 a maximum of 70 degrees. Kinetic viscosity should 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 have a thickness of at least 1.2 cm. All this will allow pumping fluid with small particles without problems. The kinematic viscosity parameter should lie in the region of 210 cSt. In this case, the nominal flow rate is 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 10 kW collector motors, then in this situation for pumps this parameter will reach 14 meters.
Pumps for the production of household chemicals
For the production of household chemicals, an impeller pump with collector engines is excellent. The limiting frequency in this case should not exceed 50 Hz. If we talk about the design features of the models, it is important to note that adapter shafts are allowed with a diameter of at least 2.6 m. Due to this, a good pressure is ensured. Also worth attention is a supercharger. In these configurations, it is installed behind the diffuser.
