Overview

The Cat Pumps 66PPX40GG1 is a bare triplex plunger pump rated 4000 PSI at 4.0 GPM, built for gas-engine pressure washers. It ships as a bare pump with no plumbing, so you can reuse your old plumbing parts to save money — though a new unloader is strongly recommended when installing a new pump, and the VRT3-310EZ unloader valve is a good match. The triplex plunger design delivers smooth liquid flow, and concentric, high-density polished solid ceramic plungers give a true wear surface for extended seal life. The compact flange mount bolts directly to most gas engines. Note: no oil is included — order it separately.

Frequently asked questions

No — the 66PPX40GG1 is a bare pump with no plumbing. You can reuse your old plumbing parts to save money, but we strongly recommend installing a new unloader; the VRT3-310EZ unloader valve is a good match for this pump.

No, no oil is shipped with this pump — you'll need to order it separately and fill the pump before running it. Running a pump dry will damage it.

It uses a compact flange mount that bolts directly to most gas engines. This lets the pump drive off the engine shaft without a separate belt or coupling setup.

The 66PPX40GG1 is rated 4000 PSI at 4.0 GPM. Match your engine, unloader, and nozzles to those figures so the system runs at the pressure and flow the pump is designed for.
