I'm sure there are some people here that can offer help as I don't own this machine and can't give you credible info on the pump. You could also e-mail CAT and ask them. If they can't answer you, nobody can. Later! CAT pumps are not the problem ,they are only building the pump.

A plunger pump’s high pressure seal is stationary and the plunger slides through the seal. This design can handle a slightly higher inlet pressure than a piston pump (60-70 psi), but requires a flooded inlet or pressure supply from a booster pump. Select a plunger pump for high pressure applications. Plunger pumps operate in an output pressure range from 100-10,000 psi. Pump is by far my favorite cat of the season.
