This is the same pump featured in the Extreme Washdown Kit 5.0GPM. It is an ideal pump for washdown purposes and can be used as a replacement for the Extreme Washdown Kit, as an upgrade for existing washdown systems, as a component in a custom washdown system, and other OEM applications. Thanks to its five-chamber diaphragm it is capable of high volume water flow with reduced pump cycling. It is self-priming and can run dry without damage. Its in-built pressure switch detects when the spray gun/faucet is open and closed, automatically starting and stopping the pump.
