Rotary Lobe Pumps
The applications that rotary lobe pumps cover are in chemical, petrochemical, pharma- ceutical, paint industries as well as general industry. In rotary lobe pumps two lobes counterrotate, driven and
synchronised by an external timing gear. This causes a steady flow from suction to discharge port.
Through the operation no parts are in direct contact inside the hydraulics, the pump can tolerate dry running. The elaborate design of the lobes eliminates pulsation and enables low shear transfer of the fluid. Rotary lobe pumps are self-priming and can be operated in either direction. If a safety valve is used, the direction of rotation is fixed.
