Hypro/Pentair is no longer distributing the 9910 series diaphragm pumps and related parts; however, the pumps and repair parts are still available and will now feature factory labeling. 

** When you order this pump, you will receive the most current version, AR30-SP**

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. See page 2 of manual for drive options.
