General information on the pump impeller.
Impeller pumps are used for pumping liquids of a wide range in m. Hr. With a content of various kinds of solids and particles, and the gas-containing products. Using the self-priming pumps with flexible impeller eliminates the destruction of the product structure in the process of transfer of the latter. Impeller (all season, self-priming) pumps are widely used in various industries (food, pharmaceutical, cosmetic, chemical industry).
Impeller pump is self-priming pump and therefore does not Bay need preliminary liquid into the inlet. Using the pump impeller allows to raise product with depths up to 5 meters.
The principle of operation of the pump impeller.
The operation of the impeller pump principle are non-symmetrical cross-section casing and impeller with flexible lamellae (impeller). Upon rotation of the impeller inlet in the volume area increases between adjacent lamellae, resulting in a discharge and the liquid flows into the pump housing. Next fluid gradually moves from the inlet to the discharge. The discharge nozzle area due to the asymmetry of the shape of the hull volume between adjacent slats of the impeller is reduced, thereby displacing the product.
Food processing industry
Impeller pumps are widely used in food, particularly in the dairy industry for pumping products such as milk, cream, melts oils (including palm) and fats, as well as various types of beverages. They are widely used for pumping products with low and medium viscosity with inclusions (pastry cream, jam, etc.).
Pump housings oriented food industry are made of stainless steel, and the impellers are made of polymer materials approved for contact with food. Impeller pumps fully meet the stringent sanitary requirements.
In the cosmetics industry impeller pumps are mainly used for pumping such cosmetic products as soap, gel, cream, toothpaste, etc.
In the chemical industry impeller pumps are used in pumping a wide variety of products, in particular paints and varnishes, acids, detergents, chemicals, dyestuffs, inks, various types of solutions, etc.
For pump impellers oriented to this industry are made of a chemically resistant rubber, which significantly increases the pump life in general.
