Pumps, Accumulators and Circuit Hardware

Displacement, pressure rating, flange and ports

The supporting hardware of a hydraulic power unit ends up here: fixed displacement gear pumps rated in cc per revolution and bar, bladder accumulators, and the fittings and adapters that tie a circuit together. Pump substitutions hinge on displacement, continuous pressure, shaft and mounting flange, plus rotation direction and port arrangement. Accumulators need volume, precharge and port thread checked. Fittings need the correct thread form, size and sealing method, since a tapered thread will not seal in a straight port. It is a short list that turns over as surplus lots arrive, so send a description of what you need if today's selection comes up short. Control components are filed under valves and manifolds.
