In this Pump Report, Chad describes a different kind of internal gear pump...the gerotor pump!

In a PD pump, each rotation of the shaft and gears carries a fixed volume of liquid from the supply tank to the downstream piping. When paired with an AC induction motor, speed and flow are very consistent. But what if you want to CHANGE the flow? In this episode of the Pump Report, Chad discusses controlling your positive displacement pump's motor with a variable frequency drive - or VFD.

In this Pump Report, Chad covers the causes and symptoms of positive displacement pump cavitation.

In the world of positive displacement pumping, reduced speed operation is a common requirement. High viscosity liquids, shear sensitive liquids, abrasive liquids, or any combination in between require the pump speed to be reduced from synchronous motor speeds. One of the simplest solutions to this - is a gear reducer.

In this edition of The Pump Report - Chad walks through the importance of understanding liquid viscosity.

Part 5/7. Viking's own Chad Wunderlich walks through the steps for the proper installation and start up of a Viking pump. In this episode, we discuss unit alignment - key to a properly functioning pump.

Symptoms and solutions of pump wear.

In this Pump Report, Chad covers two simple methods for estimating your process liquid's viscosity. 

In this video, you'll learn what causes an internal gear pump to move liquid through a process.

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.
