Hydraulic Gear Pumps

These gear pumps 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).

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


Style D	Style E	Style F	Style H

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.

Styles D-F—Styles D, E, and F have a reservoir to store test fluids.

Style H—Style H is attached to a channel base for improved leverage.

Pressure Gauge (±0.5% Accuracy), Pressure Gauge (±1% Accuracy), and Pressure Gauge (±2.5% Accuracy)—Pumps with pressure gauge can also be used for calibration.

Air-Powered Test Pumps


Style A	Style B	Style C

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—Style C has wheels for portability.

Slim-Shaft Hydraulic Power Units


	Replacement Hydraulic Tanks

Mount these units to an existing machine or where space is limited. They create and supply hydraulic pressure where standard models won’t fit. Choose a unit with a tank capacity about three times greater than your requirement to allow for heat dissipation.

Air to Hydraulic Power Units

Power a hydraulic cylinder from your air system to avoid the setup, cost, and mess of hydraulic fluid. These converters give you more consistent power than using air power for an air cylinder. However, because air works at a lower pressure than hydraulic fluid, your hydraulic cylinder won’t move loads at its full force. Attach these converters to an air line with a speed controller and solenoid (not included).

Note: These converters are not for use near fire.
