Diaphragm pumps are the most complete line of pumps available for spraying and pumping of herbicides, pesticides, liquid fertilizers and hard-to-handle fluids. Hypro offers a wide range of flows and pressures for slurries and suspensions. Pressures for row crop to treetop spraying applications range from 20 to 580 psi (1.4 to 40 bar) with flow rates to 66 gpm (249.8 lpm).

Low-cost maintenance and almost wear-free operation result from Hypro’s oil-bath design, premium quality, synthetic diaphragms for longer life, self-priming operation and visual, oil-level sight glass. These models can handle fluids up to 140°F (60°C) and can be run dry. Hypro diaphragm pumps can be driven by 540 rpm PTOs, gasoline engines or hydraulic motors.
