Popular Pressure Washer Pumps
PUMPS HIGHLIGHTED IN RED ARE OUR #1 SELLERS
4.0 - 5.6 GPM
13-18 Gas Horsepower Direct Drive
Please Note: These gas power washer pumps have 1″ hollow shafts & bolt directly to the pressure washer engine. Although you can install a 5.6 GPM @ 4000 PSI pump on a 13 Honda or 14 Kohler you will not have enough horsepower to produce rated PSI. With a 14hp engine you can expect 5.6 GPM at approximately 3000 PSI. For 5.6 & 4000 psi you will need at least 18 hp. The pump RPM gives you the GPM and the engine HP gives you the PSI.

5.5 - 6.3 GPM
18-19 Gas Horsepower Gear or Belt Drive
Note: These gas power washer pumps have 24 mm shafts & are typically used on belt drive pressure washers. If you gear drive them you will be producing more volume. Example: With the pump turning faster a 5.6 GPM pump @ 1450 RPM will produce around 6.3 GPM using a gear box on the same 3600 RPM engine.
7.0 - 14.1 GPM
18 Gas Horsepower & up Gear or Belt Drive
Please Note: These gas power washer pumps have 24 mm shafts and are typically used on gear or belt drive pressure washers. The specifications below are based on using a gear drive, which are sold separately. If you belt drive these pumps refer to our recommended pulley sizes for both 1450 and 1750 rpm pumps here…
