Rotary Lobe Pump is a positive displacement pump, which has two rotors in the pump head. The two rotors fixed on two shafts and rotate syn-chronically in counter direction. The rotation creates vacuum volume on the inlet side. The liquid is sucked into the pump head and travels around in the chamber between the rotor and the pump head casing, and is forced out on the outlet side.

FRT serial rotary lobe pump is our updated models for heavy duty applications. It has significant service life without leakage.
