Maximize the efficiency in your sprayer systems. This Hypro/AR D403GRGI (AR403) & Honda GX160 Engine Assembly contains durable, powerful components, and with a maximum pressure capacity of 580 PSI it is fabricated to handle medium-pressure spraying of many agricultural substances. With a 5.5. HP Honda commercial-grade engine, it's a champion at deploying liquid fertilizer, herbicide, pesticide and other agricultural solutions that require special care.

Hypro/Pentair is no longer distributing the 9910 series of diaphragm pumps, components, and related parts; however, the pumps and repair parts are still available and will not feature factory labeling.  

Hypro/AR medium pressure diaphragm pumps are recommended for spraying herbicides, pesticides, liquid fertilizers, and many other hard-to-handle fluids. Low-cost maintenance and almost wear-free operation make these pumps ideal for a wide variety of spraying jobs. Pressure and output are designed for optimum performance of small to medium-sized sprayers. Hypro medium pressure diaphragm pumps can be adapted for male 1-3/8" splined shaft, female 1-3/8" splined shaft, 1" solid shaft, or gear reduction drive options. Pumps include a pulsation dampener except for Models 9910-D303, D403, and D503s. Honda's GX series engines are legendary for superior reliability and performance. And there's no doubt about it: the GX160 lives up to the legend. Lower noise levels, lower vibration, and lower emissions without sacrificing power output or performance.
