Progressive Cavity Pump KIBER KS/KSF


The KS/KSF pumps are sanitary progressive cavity pumps. Due to the design, they are self-priming and reversible pumps that can suck from a maximum height of 7 meters. These types of pumps transfer products of low and high viscosity as well as products containing particles.

They are widely used to pump edible oils, wine, concentrates and beverages in general as well as viscous food products such as jam and marmalade, pasta, pate, etc. In the cosmetics industry, these pumps are used in applications involving various cosmetic products such as soaps, gels and creams.

Operating principle

Friction between the rotor and the stator creates a vacuum in the inlet area promoting the entry of the product into the pump. The rotor accompanies the product along the cavities created between the rotor and the stator up to the outlet.
