RF OENOLOGIC FLEXIIBLE IMPELLER PUMP
Application
The RF pump is a flexible impeller pump. Due to their design, they are self-priming pumps that can suction from a maximum height of 5 meters. This type of pumps can transfer products of both low and high viscosity, as well as products containing particles or gases.
It is widely used for transferring wine from one collecting tank to another and aslo for transferring must.
Operating principle
Due to the eccentric shape of the pump housing, a vacuum is created in the suction side that enlarges the volume between the blades and this causes the product suction.
The rotor is spinning and the product is carried from the suction side to that of delivery. Due
to the eccentric shape of the pump housing, in the discharge side the blades bend, reducing the volume between them and causing the discharge of the product.
