Lobe Rotor Pumps Figure

advantages These pumps can run dry for short periods as rotors have clearance, but run-dry time is limited by the seals; pumps can self-prime on low lifts; pumps can handle solids in suspension; there is little change of product velocity as it passes through the pump, so the pump has good net positive suction head (NPSH) performance, once primed; pumps can generally handle viscous materials; pumps are usually reversible.

disadvantages Fixed clearances can mean rapid performance degradation because of abrasive wear; pump has two shafts and associated shaft seals; suction lift limited at low speed/viscosity due to clearance of rotors.
