Piston Pump Design:

A Piston Pump is a Positive Displacement Pump (PDP) with a set of piston and cylinders. As the pump rotates, the pistons, driven typically by an angled “swash” plate, change the fluid volume of the cylinders. These cylinders first expand to suck in fluid and then compress to expel the fluid at into an outlet manifold via a valve plate.

Advantages:

Positive displacement, High pressure, heavy duty applications.

Application:

Transmissions, hydraulics, fluid transfer.

PumpLinx: Solve Flows, Pressures, Cavitation, and Loads:

Discriminators:

• Models cavitation
