Overview - plate (vane) pump.
The plate (vane) pumps are widely used in many sectors of the economy (food, pharmaceutical, cosmetic and chemical industries). Typically, vane pumps are applied for pumping thick (plastic) masses and viscous liquids. Vane pumps are ideal for pumping difficult flowing materials, sometimes with different kinds of solids and particles.
The principle of the plate (vane) pumps.
At the heart of the action vane pumps principle is not symmetrically mounted impeller (rotor) with radial bores, which are placed in the gate (of the plate). Upon rotation of the rotor plate tightly pressed against the inner surface of the body due to centrifugal forces. In operation, the pump inlet area of the volume between adjacent plates, the rotor and the pump housing increases, resulting in a discharge and the liquid flows into the pump housing.
Next, while rotating eccentrically mounted rotor fluid gradually moves from the inlet to the discharge. The discharge nozzle area due to the asymmetry of the rotor forms the volume between adjacent slats is reduced, thereby displacing the product.
Food processing industry
Vane pumps are widely used in moving high-viscosity products with inclusions (confectionery creams, jams, preserves, jams and other products of similar consistency). In the food industry vane pumps are widely used when transferring products such as chocolate mass, chocolate icing, the condensed milk, syrup, etc. In the dairy industry vane pumps are used to pump cream, sour cream, cottage cheese weight and other products similar to those named in consistency.
Details of housing and rotor plates pumps focused on the food industry are made of materials approved for food contact and approved for use. Vane pumps fully meet the stringent sanitary requirements
In the cosmetic industry vane pumps are used, usually soaps during pumping, various types of gels, creams, toothpaste, etc.
In the chemical industry vane pumps are used in pumping a wide variety of products, in particular paints and varnishes, various adhesives, detergents, dyes, various types of solutions, etc.
For this oriented pump housing industry, the rotors and the plates are made of metal resistant to the most specific type of product, which significantly increases the pump life in general.
