The KVB-25 pumps are hygienic vertical progressive cavity pumps. Drum pumps are specially designed to transfer media of either high or low viscosity from tanks and barrels by means of a pump tube introduced into the drum.
Some of the most important applications of this pump type is transferring of fruit concentrates for the beverage production, tomato concentrate for the ketchup production, transferring of creams, honey and other media of high viscosity.
Pumping is characterised by a gentle transfer of media with shear sensitive particles.
Operating principle
The pump tube is introduced into the drum with the media to transfer.
Friction between the stator and the rotor creates vacuum at the inlet of the pump thus facilitating the entry of the product into the pump.
The turning motion of the rotor makes the cavities between the rotor and the stator move forward and transport the product to the outlet.
