Product Overview

The Pentair Hypro D50GRGI8 with the Honda GX270 engine is designed for long-lasting small to medium scale commercial spraying. This pump and engine assembly is built to deliver up to 14.8 gpm and 580 psi. Lightweight, but powerful, the D50 uses diaphragms to separate the chemical you are spraying from the internal components of the crankcase for a long pump life.

Hypro/Pentair is no longer distributing the 9910 series of diaphragm pumps, components, and related parts. Products with Hypro labeling will be unavailable soon.

Manufacturer description

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. With the GX270, you're looking at one of the best engines in the business. More power. Quieter performance. Lower fuel consumption. Lower emissions. Better features. Exceptional performance. Honda's GX series lives up to the legend, and then some.
