Applications
The RF pump is a flexible impeller pump. Because of their design, these pumps are reversible and self-priming that can suction from a maximum height of 5 meters. This type of pumps can pump materials of both low and high viscosity, as well as materials containing particles or gases.
Their main uses include pumping in dairies, edible oils, wine, concentrates and beverages in general. They can also be used with viscous food products such as jam and marmalade, confectioner's custard, as well as cosmetic products such as soap, gels, toothpaste, and cosmetic creams. Other applications include the dying, textile and chemicals industries.
Operating principles
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.
