Description
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 centrifugal pumps can also be
used to pump acid fertilizer, calcium chloride and other highly
corrosive liquids such as sulfuric and phosphoric acids.
Hypro Series 9300 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.
