Flexible Impeller Pumps With Gear Motor:
The RF pump is a flexible-impeller pump. Due to the design, these pumps are reversible and self-priming and can suction from a maximum height of 16 feet. This type of pump is designed to pump products of both low and high viscosity, as well as materials containing particles or gases.
The RF pump is available with two drive options: standard motor and gear motor types. The gear motor type can move product in both directions with the use of a variable frequency drive (VFD). Maximum suction lift of 16' can also be achieved dependent on the pump size.
The main applications are transfer of dairy products, edible oils, wine, concentrates and beverages in general. They can also be used with viscous food products such as jam and marmalade, custard as well as cosmetic products such as soap, gel, toothpaste and creams. This pump is used in dying, textile, and chemical industries.
It is widely used for transferring wine from one collecting tank to another and also for transferring must.
Due to the eccentric shape of the pump housing, a vacuum is created in the suction side as the volume between the blades increases causing the suction of the product.
By spinning the rotor, the product is carried from the suction side to the discharge side.
Due to the eccentric shape of the pump housing, in the discharge side the blades bends, reducing the volume between them and causing the discharge of the product.
