Built for Real Farm Work
This control unit is designed for AR’s D30 and D50 series diaphragm pumps, which are commonly found on spray rigs, tank mixers, and pressure washing setups around the farm. Whether you’re running herbicide applications, livestock spraying systems, or cleanup equipment, this unit handles the pressure control and distribution duties.
Made to Last
AR builds their pump components to handle the chemicals, pressure cycles, and vibration that come with agricultural spraying work. The relief valve keeps things running at safe pressures, while the individual outlet shutoffs let you control exactly where your flow goes without having to shut down the whole system.
Good to Know
The unit comes ready to mount and includes all the pressure relief and outlet control components you need. Make sure your existing pump is compatible with D30 or D50 series before ordering. Having individual shutoffs on each outlet is handy when you need to isolate sections of your spray system for maintenance or different applications.
