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.

External gear pumps are positive displacement pumps that cover a wide range of applications. The applications are in chemical, petrochemical, pharma- ceutical and paint industries as well as in general industry. In external gear pumps two counterrotating gears of equal size are enclosed in the casing. The gears transmit the torque as well as the fluid.

Internal gear pumps are positive displacement pumps that cover a wide range of applications. In internal gear pumps two counter rotating gears of equal size are enclosed in the casing. The driving gear transmits the torque as well as the fluid.

The idling gear which is guided on a product lubricated eccentric pin, transmits fluid and seals the suction from discharge side. The fluid is transferred in the chambers between the gear teeth by rotation of the gears from the suction to discharge side. Internal gear pumps feature low pulsation operation.
