Buying Guide

Match shaft size and orientation

Confirm your machine's shaft diameter (7/8" or 3/4") and whether it uses a vertical or horizontal pump to ensure fitment

Check PSI and GPM range

Choose a pump rated near your washer's original PSI/GPM to avoid underperformance or overloading the engine

Inspect materials and seals

Look for brass fittings, ceramic plungers, and quality seals to improve durability and reduce leak risk

Compatibility with gasoline engines

If your washer has a gas engine, verify the replacement is specified for gasoline-engine-driven units for proper cooling and mounting

Mounting and hardware included

Prefer pumps that include mounting bolts and inlet/outlet fittings to simplify installation and reduce extra parts needed
