** When you order this pump,  you will receive the most current version, AR50-SP **

Include this superior grade, sturdy Hypro/AR D50 Pump in your sprayer system for maximum effectiveness in substance deployment. With a maximum pressure capacity of 580 PSI and a flow limit of 14.8 GPM, it's ideal for use in assemblies where medium pressure is needed. Use in sprayers delivering herbicides, liquid fertilizers, pesticides and other liquids that require extra care.

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 except for Models 9910-D303, D403, and D503s. See page 2 of manual for drive options.
