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) 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) thread connections have straight threads and are also known as O-ring Boss fittings.
