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.
