The semi-hydraulic Hypro/AR D403GRGI offers optimum pumping performance for small to medium-sized sprayers. Combine that with a Honda GX160 electric start engine and you have a true powerhouse that's ready for agricultural or industrial use. Dual oil drains and fill, helical cut gears and a forged steel crankshaft are just a few of the details that set this motor apart.

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 now feature factory labeling. 

Hypro 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.
