Home Pumps Positive Displacement 

High Pressure Positive Displacement Pumps

    Positive displacement pumps are just that. For every revolution of the shaft each cylinder or chamber displaces a certain amount of water based on bore and stroke. Directed by valves this water must go somewhere or the pump will be damaged. 

    Due to these characteristics, systems must be carefully designed with safety relief and unloader or by-pass valves carefully adjusted.
 Common uses are pressure washers, deep well injection, chemical injection and high pressure coolant for machine tools.
