Designed for Pros. Updated for 2025.
The BE SW1165HC2 Gas Soft Wash Unit has long been considered one of the most reliable, high-performance soft wash systems on the market…and it just got a whole lot better.
Now equipped with the new Comet P40 diaphragm pump and Honda GX200 engine, this 11.0 GPM, 300 PSI gas-powered soft wash system is designed to deliver a smooth, consistent flow of water and chemicals on the most demanding soft wash applications.
The new 2025 Comet P40 offers an increased ¾” bypass port for better chemical flow, a more robust pump housing and improved self-priming performance for more suction and better chemical pumping capacity.
In addition to a polypropylene body and one-piece molded collector that resists the harshest chemicals, reduce leak points and make cleaning and maintenance easier, the entire P40 pump has been engineered to last for daily use in some of the harshest working conditions—from roof washing, siding wash and more to agriculture, lawn spraying, pest control and beyond.
