Hydraulic drive Hypro pump - Cast Iron model - 9303C-HM4C
The Hypro 9303C-HM4C is a heavy-duty hydraulic motor-driven centrifugal pump built for demanding agricultural and horticultural spraying applications. Commonly retrofitted to broadacre, trailing, and vineyard sprayer units, this cast iron pump delivers reliable high-flow performance in both open and closed spray systems.
Driven directly from the tractor's hydraulic system, the 9303C-HM4C eliminates the need for PTO engagement — freeing the PTO for other tasks. The close-coupled design minimises mounting space and removes the need for long shafts or couplers between pump and motor.
Handles a wide range of spray fluids including water, herbicides, insecticides, wettable powders, emulsifiable concentrates, and liquid fertilisers.
