All EnviroSpec Pumps can be purchased “Ready To Go”. These pumps come with everything that you’ll need to just simply mount the pump when you receive it!!
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 those specs. With this set-up expect 5.6 gpm at approximately 2800 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.

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.
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…
