Series 9303P-Polypropylene

Series 9303P-Polypropylene

Hypro centrifugal pumps are designed for agricultural and industrial spraying and transfer of a variety of fluids: water, insecticides, herbicides, wettable powders, emulsives, liquid fertilizers, etc. Polypropylene may also be used to pump acid fertilizer, calcium chloride and other highly corrosive liquids such as sulfuric and phosphoric acids.

Hypro hydraulic motor-driven centrifugal pumps provide smooth performance. They can be conveniently mounted on the tractor or sprayer, becoming part of the vehicle’s hydraulic system and freeing the PTO for other uses. The Hypro “close-coupled” design reduces the mounting space required, eliminating long shafts and couplers between the pump and motor.

The series includes models 9303P-HM1C, 9303P-HM2C, 9303P-HM3C, 9303P-HM4C, and 9303P-HM5C.
