Product Description

The Hypro D30GRGI (9910-D30GRGI) is a D30 diaphragm pump that comes assembled with a Pressure Regulator (9910-GS40GI) and a Gearbox (9910-KIT1640) ready to mount on a gas engine.

The Hypro D30GRGI is the most sought-after diaphragm pump for pumping and spraying herbicides, pesticides, liquid fertilizers, and other hard-to-handle fluids, establishing itself as the lawn care industry standard in the agricultural and landscaping industries.

Low-cost maintenance and almost wear-free operation result from its oil-bath design and premium quality synthetic diaphragms for longer life, providing you with greater reliability in the field because the pump will not damage easily when working with corrosive, harsh, and common agricultural chemicals.

The Hypro D30GRGI is typically found on weed sprayers and Lesco Skid Sprayers. Another use for this Hypro medium pressure diaphragm pump is as a hydrostatic test pump for pressure testing pipes and sewers.
