Hygienic Rotary Lobe Pumps

The rotary positive displacement pump incorporates the very latest in hygienic design concepts in order to fulfill the ever increasing customer demands for improved cleanability, hygiene and sterile ability. With the most stringent hygienic standards, the flush rotor fixing screws are sealed to prevent product ingress.

Low maintenance costs are due to the front loaded single shaft seals that are fully accessible from the front of the pump without disturbing the process pipework.

The bi-wing rotors incorporate the low viscosity efficiency associated with circumferential piston pumps with the viscous product handling capabilities of tri-quad and bi-lobe rotor pumps for high volumetric efficiency.

The rugged design features extremely large shaft diameters mounted in high specification taper roller bearings, fitted into an extremely rigid central pillar made from a high grade alloy. This is all enclosed in an oil filled housing made from the same alloy.

These, together with wide tipped rotor wings, adds another dimension to security, to avoid premature pump failure due to overpressure or other abuse.
