Description

The AR45 Soft Wash Pump delivers high-volume performance for professionals handling roofs, siding, and other exterior cleaning tasks. It pushes up to 11.4 GPM at a max pressure of 290 PSI, providing steady flow for both residential and light commercial work.

It uses Viton® diaphragms to handle harsh chemicals like sodium hypochlorite and maintain long-term durability.

This model includes a gearbox, allowing direct mounting to compatible gas engines like the Honda GX200. It features a gear-driven design that ensures smooth operation and reliable output in the field. Additionally, the pump is pressure gauge compatible, so you can monitor spray performance as needed.
