The PVV41-1X/122-018RA15UUMC pump is manufactured by Bosch Rexroth for the PV Fixed Displacement Pumps series and supplies constant-volume hydraulic power to automation machinery. The unit turns clockwise, and it mounts with an SAE J744 flange that follows the SAE-C (127-2) bolt pattern for direct coupling to standard drive motors. A SAE 3-inch suction port minimizes inlet losses at the permissible 1800 rpm speed limit. On the cover side, displacement is 18.0 cm³, which yields 26 l/min at 1500 rpm for auxiliary circuits. An NBR seal contains the fluid, and the overall weight is 34 kg for straightforward installation.
The flange side delivers the primary flow, providing 121.6 cm³ per revolution and 177 l/min at 1500 rpm. This side connects through a SAE 1 1/4-inch pressure port and is rated for 175 bar continuous pressure, while the cover side is cleared for 210 bar to support higher pilot loads. The cover side pressure exits via a SAE 3/4-inch port, allowing smaller hoses to carry control oil. Separate pressure ratings and dedicated port sizes let the pump feed two circuits with different demands from one housing, ensuring reliable hydraulic automation without additional pumping stages.
