Description
When you’re running a serious sprayer setup, having proper control over your pump operation is critical. This control unit is designed to mount directly on AR 9910-D303 and 9910-D403 pumps, giving you the pressure management and flow control you need to get your spraying done right. With capacity for 11 GPM flow rates and handling pressures up to 580 PSI, it’s built for the demands of commercial spraying operations.
What You’re Getting
- High-pressure relief valve that’s adjustable so you can dial in the exact pressure for your application
- Complete bypass lever that lets you quickly redirect flow when you need to move between fields or refill
- Two individual 1/2 inch HB outlets with their own shut-offs for precise section control
- Built-in 2-1/2 inch pressure gauge so you can monitor system pressure at a glance
- One 5/8 inch HB bypass connection for efficient flow management
Built for Real Spraying Work
This control unit is engineered specifically for the AR 9910 pump series that powers many commercial and farm sprayers. These pumps are workhorses in applications from field spraying and pasture management to equipment cleaning and liquid fertilizer application. The 11 GPM capacity handles everything from broadcast spraying with wide booms to spot treatment work.
Made to Last
Commercial spraying puts control units through constant pressure cycling, chemical exposure, and vibration. This unit features robust construction with quality valves and fittings that maintain their settings and sealing integrity through seasons of hard use. The pressure gauge is built to handle the bumps and weather that come with field work.
Installation Notes
This unit bolts directly to the pump housing on 9910-D303 and 9910-D403 models – it’s a direct factory-style replacement. If you need to mount the control unit remotely from the pump, kit 9910-KIT1741 provides the necessary hardware and connections. Make sure to use thread sealant on all pressure connections to prevent leaks.
