Impeller pump: device. Impeller pump with own hands

An impeller pump is a device that is equipped with a flexible working element. Models are used to inject liquid with increased viscosity. Also, pumps are often used for pumping. To date, various models are actively used in the pharmaceutical, perfume, dairy, canning and other areas.

With thick liquids, devices can also work, but in this situation much 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. For pumping emulsions they are ideal. In this case, various small particles can be contained in the liquid.

Pump unit

An impeller pump without an engine is an impeller. It is connected to the transition shaft. At the end of it there is a special head. The superchargers of pumps are of different types. A separate hole is provided for sucking the liquid. 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 make your own hands?

Pumps for dairy products, as a rule, are made with oblong chambers. The engines on them are often installed in a collector type. The superchargers, in turn, are steel. Directly transition shafts are of small diameter. For dairy products, models with a high speed parameter are required. If we talk about power, then on average it fluctuates around 20 kW. The nominal flow rate is 4 cu. Meter per hour. Kinematic viscosity of the device of this type is maintained at 210 cSt.

Devices for fat-and-oil products

For fat-and-oil 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 models, then attention deserves the impellers. The guides are of short length, but they can withstand large loads.

The impeller is installed directly in the chamber. Transition shafts in models by diameter are quite different. The engines are most often encountered asynchronous type with a power level of 15 watts. The head of the devices reaches 11 meters. The nominal feed rate parameter, in turn, does not exceed 6 cu. Meters per hour.

Features of models for the production of confectionery

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

Transition shafts are used with a diameter of 2.1 cm. The superchargers are most often installed behind the diffuser. The heads of the models are available with denticles. As a rule, the guides are of short length. The nominal pump flow rate is at the level of 4 cu. Meters per hour. At the same time, the pressure parameter is not more than 13 meters. Suction nozzles are used in various diameters.

Pumps for fruits and vegetables

For fruit and vegetable products, an impeller pump is required with a large suction nozzle. Work devices should be at a temperature of at least 70 degrees. The engines on the models, as a rule, are installed in a collector type with a power level of 15 kW. They work from a network with a voltage of 220 V and an operating frequency at 55 Hz.

Transient shafts are short. Thus, the nominal feed rate of the devices is negligible. 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, the market has many modifications with shirts. The average noise level is 60 dB.

Pumps in the cosmetic sphere

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

Models for perfume production

For the manufacture of perfumery, an impeller pump, as a rule, uses a small 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 equal to 53 Hz. Immediately transitional shafts are used with a diameter of about 2.5 cm. The size of the suction nozzles of the model is quite different. In this situation, much depends on the volume of the main camera. Superchargers are often made of steel. The guides for such devices are only suitable for flat ones.

Diffuser in many models is located near the wheel. If we talk about the parameters of the pumps, it is important to mention the nominal feed. On average, this figure 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 maximum 70 degrees. The kinetic viscosity must be at least 230 cSt.

Pumps in pharmaceutics

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 make it possible to pump liquid with small particles without problems. The kinematic viscosity parameter must lie in the region of 210 cSt. At the same time, nominal flow is welcomed no lower than 4 cu. Meters per hour. Additionally, the head index is taken into account. On average, it is 12 meters. However, if we consider modifications with collector motors of 10 kW, in this situation, the pumps will reach this parameter 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 about the design features of the models, it is important to note that the transition shafts are allowed with a diameter of not less than 2.6 m. Due to this, a good head is provided. Also, the supercharger deserves attention. In these configurations, it is installed behind the diffuser.

Directly impellers on the diameter can be different. On average, the nominal feed rate is 4 cu. Meter per hour. The motors in this case have a power of at least 12 kW. For a liquid, the maximum temperature is allowed to be 75 degrees. Many models are made by manufacturers with shirts.

Models for working with petroleum products

For the transfer of petroleum products, pumps can be found in a wide variety. First of all, it is important to mention compact models whose power does not exceed 10 kW.
