Hypro 9910-D252 Medium Diaphragm Pressure Pump
Hypro Medium Diaphragm Pressure Pump
This medium pressure diaphragm pump is recommended for ground and low-level spraying of herbicides or pesticides commonly used by landscapers, greenhouse operators and pest control companies. 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.
The 9910-D252 pump has 2 Diaphragms, 3/4" solid keyed shaft: 6 gpm; 290 psi. This is the pump only, you cannot use this to replace a gearbox driven pump.
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 medium to large sized sprayers. The Hypro D252 diaphragm pump is designed to be the most complete pump for the spraying and pumping of herbicides, pesticides, liquid fertilizers and hard-to-handle fluids. The oil bath design and premium-quality, synthetic diaphragms provide longer life and greater reliability.Low-cost maintenance and almost wear-free operation result from these diaphragms,as well as, a self-priming operation, and visual oil-level sight glass. This Hypro D252 diaphragm pump can handle fluids up to 140 degrees F and can be run dry. Easily adaptable to PTO, hydraulic or gas engine drives. The regulator is easily replaced, see below to order the control unit. ?When your pump has mixed oil (the oil in the sight glass is milky gray in color) do not run the pump any more, you need to change the diaphragms. Running a diaphragm pump with mixed oil will destroy the pump in a short period of time. This pump requires SAE 30 oil, commonly known as "30 weight" oil, non detergent, so no 10W30 in these pumps.
