Please note - the 252 regulator has been completely upgraded and now features the GR20, bringing improved performance and enhanced usability. Key enhancements include two discharge ball valves with 1/2” hose barbs, 3/4” bypass, and a pressure gauge.

For your agricultural spraying needs, install this Hypro D252GRGI (AR252) & Honda GX160 Engine. Designed to deliver medium pressures up to 290 PSI, it features a Honda OHV commercial-grade engine that is both powerful and durable and is available with either a recoil or an electric starter. This product is highly recommended for delivering pesticide, herbicide, liquid fertilizer, or other liquids that require special care.

Hypro/Pentair is no longer distributing the 9910 series of diaphragm pumps 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. Pressure and output are designed for optimum performance of small to medium-sized sprayers. 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.
