Impeller pump

Impeller pump belongs to vane rotary pumps and is a positive displacement pump. It is referred to in different ways: a flexible vane pump, a soft rotor pump, or a flexible impeller pump. However, all these names refer to the same type of pump — the impeller pump.

Fields of application: food industry, cosmetics industry, chemical industry, and pharmaceutical industry.

The pump is used for pumping thick and viscous products such as honey, jam, yogurt, preserves, condensed milk, etc.

In the cosmetics industry, it is used for pumping shampoos, face masks, gels, creams, and lotions.

The impeller pump consists of two main parts: the electric motor and the pump housing.

The pump uses a closed-type asynchronous electric motor with a maximum shaft rotation speed of up to 1,500 revolutions per minute. Most commonly, pumps with an electric motor operating at 900 rpm are used. The power range of electric motors for impeller pumps varies from 0.55 kW to 6 kW. Pumps are available both with and without a motor.

The pump housing consists of a front cover, a rear cover, a flexible impeller, a mechanical seal, and a mounting flange.

The moving part of the pump — the impeller — is located inside the housing and positioned between the front and rear covers. It is a wide, monolithic open-type impeller with a varying number of flexible blades. The width of the impeller affects the pump capacity. The flexible impeller pump is self-priming and can lift the product from a depth of up to 5 meters.

The impeller pump combines the capabilities of a centrifugal pump and a positive displacement pump: it creates pressure and flow while also being able to pump thick and viscous liquids.
