9303C / 9303s

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.

Hypro Series 9303 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 broad, versatile line includes models with rugged housings of cast iron and stainless steel that stand up to strong chemical herbicides. Stainless steel pumps are ideal for use with Roundup® or other acid applications.

9303C and 9303S pumps are stocked by Pumps and Sprays, Australia’s Hypro specialists.
