Centrifugal Pumps

Pump capabilities range up to 440 GPM and 190 PSI. The broad, versatile line includes
models with rugged housings of cast iron, stainless steel and polypropylene that stand up
to strong chemical attack. Stainless steel pumps are ideal for use with Roundup® or other
acid applications. Polypropylene pumps are lightweight and provide excellent resistance to
corrosive chemicals. Choose from gear, pedestal, flange, DC clutch, hydraulic motor and belt
drives, as well as models that are closed-coupled to gasoline engines.

Diaphragm Pumps

These models can handle fluids up to 140°F (60°C) and can be run dry. Low-cost
maintenance and almost wear-free operation result from Hypro’s oil-bath design, premium
quality, synthetic diaphragms for longer life, self-priming operation and visual, oil-level sight
glass. Diaphragm pumps are the most complete line of pumps available for spraying and

steel valves and ball bearing, leather or fabric-reinforced Buna-N or straight Buna-N cups.
You can choose from a variety of drive systems to include: belt and pulley, 540 rpm PTO,
gasoline engine or electric motor. These pumps are available in a variety of flow and pressure
ranges up to a maximum of 1 GPM /37.9 LPM and 1000 PSI /68.9 bar with maximum fluid
temperatures of 140°F/60°C (piston pumps) and 180°F/82°C (plunger pumps).

Roller Pumps

These pumps contain rollers that revolve inside the pump housing to force the spray solution
through the outlet to the nozzle. Hypro roller pumps are easily adaptable to PTO, gas engine
or electric motor drives. Roller pumps are used for spraying and transferring a variety of fluids
including insecticides, herbicides, fungicides, emulsions, aromatic solvents, liquid fertilizers
and many other non-abrasive liquids. All pumps are available in three materials: Cast Iron,
Ni-Resist or Silver Series XL®.

Squeeze Tube Pumps

Oval shaped tube with built-in back plate insure accurate rates. The positive shut -off is due
to the positive sealing tubes. 8-48 outlets are available. Outlets can be doubled for higher
rates. Sealed for life bearings require no lubrication.
