Generic 1 inch Shaft Triplex Pressure Washer Pump 4200 PSI 4.2 GPM - this new pump just kicks it! 1″ Shaft Triplex Pressure Washer Pump 4200 PSI 4.2 GPM Replacement Power Washer Pump Compatible with GX340 GX390 GX270 DXPW3035 DXPW3535
I had a high performance Simpson Professional Pressure washer with a failed AAA pump. This triplex pump was rated at 4200 PSI and 4.0 GPM. The Honda GX390 engine was still in great shape.
I found this Generic 1″Shaft Triplex Pressure Washer Pump 4200 PSI 4.2 GPM on Amazon with similar specs and one half the price of a new AAA pump. It arrived already filled with oil and was easy to bolt up to the GX390 once I applied a thin coating of anti-seize lubricant to the motor shaft. I also removed the top oil filler plug (on the pump) and installed the breather valve (cap) per instructions. It took less than 30 minutes for installation.
And once again my professional pressure washer with this new Generic pump just kicks it!
