Q: What is the difference between a washdown pump and a water pressure system pump?

 

A: Washdown pumps traditional operate at higher pressures than pressure system pumps. Also the elastomers (rubber components) in the pumps are different. A pressure pump uses Santoprene and EPDM elastomers which are suitable for drinking water, a washdown pump uses Nitrile elastomers which are not suitable for drinking water.
