What is a Gerotor Pump?
In this Pump Report, Chad describes a different kind of internal gear pump...the gerotor pump!
Slowing Down Your Pump's Motor with a Variable Frequency Drive (VFD)
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.
What causes pumps to cavitate? And why is my pump so LOUD?
In this Pump Report, Chad covers the causes and symptoms of positive displacement pump cavitation.

Gear Reducers and Pump Operation
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.

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.
