Chemical Injector for Pressure Washing

The Dayton 1MCZ7 is a brass adjustable chemical injector designed for pressure-washing systems that operate between 2 and 3 gallons per minute. It introduces cleaning agents downstream of the pump so operators can apply detergents without exposing the pump seals to harsh chemicals.

Integration With AR North America Pumps

The injector carries a 3/8-inch BSP discharge connection and is listed as compatible with a range of AR North America pump models including 1MCX7 through 1MCX9, 1MCY1, 1MCY2, 1MCY8, 1MDB2, 1MDB3 and 1WXW7 through 1WXW9. Installers thread it directly into the pump discharge port, leaving the high-pressure hose and spray gun to connect downstream without additional adapters.

Flow Capacity and Pressure Limit

Rated for a maximum flow of 3 gpm and a discharge pressure of 4,000 psi, the unit handles typical residential and light-commercial pressure washers. Systems that exceed either the flow or pressure rating will require a different injector, and the adjustable metering does not compensate for oversized pumps.
