Diaphragm pumps are lightweight, compact, self-priming, and require less horsepower compared to other pump types with similar flow and pressure ratings. Models which require pulsation dampening have the dampers built onto the manifold. Like piston pumps, diaphragm pumps are positive displacement; output remains constant with pump speed.

Hypro's medium pressure D30 diaphragm pump is recommended for shrub, fruit and ornamental tree spraying as well as ground spraying. Pump has anodized aluminium housing and includes a pulsation dampener. Wetted parts are epoxy-coated for resistance to chemicals and fertilizers.
