Diaphragm pumps are lightweight, compact, self-priming, and require less horsepower compared to other pump types with similar flow and pressure ratings. Models that require pulsation dampening have the dampers built onto the manifold. Like piston pumps, diaphragm pumps are positive displacement so output remains constant with pump speed. Recommended for spraying herbicides and fertilizers both pre-emergent and post-emergent. Drive section of pump runs in oil for smooth, maintenance-free performance. Wetted pump parts are epoxy coated for superior corrosion resistance.
