How Does a Gerotor Pump Work?

In this video we describe how gerotor pumps move liquid. Gerotor pumps are similar in operation to traditional internal gear pumps but swap the position of the drive and driven gears and do not use a crescent to create the gear offset. To learn more visit our website at vikingpump.com.

Running Internal Gear Pumps in Reverse

Internal gear pumps can be easily converted from one direction of rotation and flow to the other; or even be made to run in two directions of rotation and in two directions of flow. The capacity of the pump remains constant in either direction, making this a beneficial and unique feature of the Internal Gear pumping principle.

Pump Report | Relief Valves

Rotary positive displacement pumps are flow generating machines. With each revolution of the shaft, a fixed volume of liquid is moved from the inlet to the outlet. But what if the discharge line becomes blocked? In this Pump Report, Chad Wunderlich discusses the importance of overpressure protection using relief valves.
