The PVV51-1X/162-046RA15LRMC is a fixed-displacement pump from the PV Fixed Displacement Pumps series manufactured by Bosch Rexroth for constant-flow hydraulic automation tasks. On the flange side, the pump displaces 162.2 cm³ per revolution, and that volume yields a maximum flow of 234 l/min when the drive speed is 1500 rpm. A continuous pressure limit of 175 bar on this side allows it to supply high-pressure circuits without intermittent relief. The flange-side pressure port is a SAE 1 1/2 in connection situated on the left, simplifying pipe runs where the machine layout favors that orientation. An SAE-C mounting flange lets the housing bolt directly to common industrial power units. Clockwise rotation aligns with standard engine and motor outputs, while a minimum speed of 600 rpm keeps internal lubrication effective and a maximum speed of 1800 rpm defines the safe upper operating boundary.
The cover side of the same pump handles lighter service demands with a displacement of 45.9 cm³ per revolution and a resulting flow of 70 l/min at 1500 rpm. Its continuous pressure capability is 140 bar, making this section suitable for auxiliary actuators that need lower force. The cover-side pressure port uses a SAE 3/4 in size and faces right so that high-pressure and return lines can be separated cleanly inside crowded manifolds. A suction connection sized at SAE 3 1/2 in delivers ample inlet area to both pumping groups, reducing the chance of cavitation during fast cycles. Together, the two pressure stages and the defined porting positions let system designers route high- and low-flow circuits from one compact, fixed-speed source.
