Drum Pumps for Water and Chemicals




Push the plunger to pump water, cleaners, and chemicals.
Styles A, B, and G are for thin liquids with a maximum viscosity of 700 or 750 centipoise.
Styles C-F are rated for liquids up to 2,500 centipoise. Style C are often used as hand pumps and do not come with a connector. To attach them to a container, select an optional connector.

Hydraulic Pumps
Also known as gear pumps, these have few moving parts so they're less prone to wear than other hydraulic pumps. Combine with an electric motor to generate flow in a hydraulic system. To mount to a NEMA C-face motor, use a Pump-to-Motor Mount (sold separately).
UN/UNF (SAE Straight) thread connections have straight threads and are also known as O-ring Boss fittings.

Smooth-Operating Hydraulic Pumps
These pump hydraulic fluid more evenly than standard hydraulic pumps, resulting in less noise and vibration. Also known as vane pumps, they have replaceable vane cartridges that simplify the repair process. Combine with an electric motor to generate flow in a hydraulic system.

Hydraulic Power Units

Create and supply hydraulic pressure. Choose a unit with a tank capacity about three times greater than your requirement to allow for heat dissipation. An inlet filter protects the pump from contamination.
All units include an additional NPTF threaded inlet port. NPTF (Dryseal) threads are compatible with NPT threads. UN/UNF (SAE Straight) thread connections have straight threads and are also known as O-ring Boss fittings.

Manual Pumps for Testing and Calibration




Manually pump air, water, or hydraulic fluid through your system so you can test fluid pressure in valves, hose, sprinkler lines, pipes, boilers, condensers, heat exchangers, pressure vessels, and other pumps. Pumps with pressure gauge can also be used for calibration.
Styles D, E, and F have a reservoir to store test fluids.
Style H is attached to a channel base for improved leverage.

Air-Powered Pumps for Testing
These pumps use compressed air to pump water or hydraulic fluid at high pressures through your system for leak testing. They come with a regulator that shuts off the pump when the desired air pressure is met and restarts it when the pressure drops.
Style C has wheels for portability.
