EZ4040G Pressure Washer Pump 

The EZ4040G General Pump is a reliable, high-performance pressure washing option. It is designed using a forged brass manifold. The pump incorporates an SAE J609 gasoline mounting flange with which you can mount up to 13 HP engines. 

Another benefit of the EZ4040G pump is its unique durability. It offers a maximum fluid temperature of 165 F. It can operate at a speed of up to 3400 RPM. It's capable of supporting a discharge pressure up to 4200 PSI to go with a maximum inlet pressure of 125 PSI. 

The list of worthwhile features continues to expand and includes its forged brass manifold with 3:1 hydrostatic rating, its premium roller bearing, its die-cast, anodized aluminum oil-bath crankcase, and its clever one-piece plunger design which eliminates water entering the crankcase.
