About this product
This BFO Pressure Washer Pump is a gas-powered, cold water triplex plunger unit designed for heavy-duty applications. It delivers a maximum discharge pressure of 4000 PSI and a flow rate of 4.0 GPM, operating at up to 3,400 RPM. Featuring a 1" horizontal hollow shaft, it's explicitly suited for Honda GX270 and GX390 engines, serving as an aftermarket replacement for parts like RSV4G40. The pump can handle fluid temperatures up to 165 degrees Fahrenheit and has a 16oz oil capacity.
Our take
For those needing a robust replacement or upgrade for a gas pressure washer, this BFO triplex plunger pump offers serious capability. The 4000 PSI and 4.0 GPM output are impressive, making it suitable for demanding cleaning tasks. The 1" horizontal shaft is specifically designed for Honda GX series engines, so verify compatibility carefully. The 165-degree fluid temperature tolerance is a nice touch for extended use. Keep in mind it's an aftermarket part, so while it promises high performance, double-check your existing setup's requirements.
