Product Description

The Hypro D30 Diaphragm Pump (9910-D30) is our most popular diaphragm pump for landscaping and agricultural applications, as it surpasses all of the competition to become the lawn care industry standard for the pumping and spraying of herbicides, pesticides, liquid fertilizers, and many other corrosive, abrasive, and general use chemicals.

A low-cost maintenance and almost wear-free operation make this Hypro medium pressure diaphragm pump perfect for numerous spraying jobs, including the chemical spraying of shrubs, trees, and turf. With a maximum 8.5 GPM and 580 PSI, the combined volume and pressure allow for the spray to reach up to 35' high. Pressure and output are designed for the best performance of small to medium-sized sprayers, so it is common to find the D30 on weed sprayers and Lesco Skid Sprayers. Another use for the D30 is for pressure testing pipes and sewers as a hydrostatic test pump.

The 9910-GS40GI Pressure Regulator (sold separately) is required for the Hypro D30. If you want a modified D30 that includes a Gearbox and Regulator ready to attach to a gas engine with a 3/4" keyed shaft, then the Hypro D30GRGI (sold separately) is more suitable for you.

You can adapt the Hypro D30 duplex diaphragm pump to a male 1 3/8"-6 splined PTO shaft (KIT 1702), female 1 3/8"-6 splined PTO shaft (KIT 1704), 1" solid shaft (KIT 1703), or gear reduction drive options (KIT 1640).
