Rexroth Hydraulics Hydraulic Gear Pump, External Gear Design Model P

This Rexroth Hydraulics pump features compact two-piece cast aluminum body and cover construction. Single piece shaft gears and driven gears for superior strength as well as high volumetric efficiencies maintained by the hydrostatically loaded flange block bearing system. Internal relief valve options available. Side and rear port options available.

Fixed Displacement Piston Pump, Bent Axis Design

Fixed displacement Axial Piston Pump for open circuits in addition to SAE 2 or 4-bolt mounting flange and spline shaft. Compact high power to weight ratio. Heavy duty tapered roller bearing design, easily serviced, for long pump life as wellas SAE flanged or threaded connections. Patented one piece conical piston design, with two piston rings for excellent sealing. Lightweight with high shaft loading capability in addition to continuous pressure to 5800 PSI (400 bar) with intermittent pressure to 6500 PSI (450 bar). Excellent volumetric efficiency as well as eleven different sizes for optimum displacement selection.
