The PVV42-1X/098-045RA15DDMC is a fixed-displacement pump in the PV Fixed Displacement Pumps series from Bosch Rexroth, intended to supply consistent hydraulic flow in automated machinery. A displacement of 45.4 cm³ per revolution on the cover stage establishes the volume transferred each shaft turn for auxiliary functions, while 97.7 cm³ per revolution on the flange stage supports primary circuits that need higher output. At 1500 rpm these stages deliver 66 l/min and 141 l/min respectively, providing two predefined flow rates for parallel actuation tasks. The unit operates between 600 rpm and a permitted 1800 rpm when inlet pressure is 1 bar, allowing designers to match pump speed to engine or motor characteristics. A continuous pressure limit of 175 bar enables the pump to maintain system force without overstressing internal components.
Clockwise rotation defines drive coupling orientation so the installer aligns the pump correctly with the prime mover. An SAE-C 127-2 flange following the SAE J744 mounting standard simplifies replacement in existing frames. The cover side uses an SAE 1 in. pressure port and the flange side uses an SAE 1 1/4 in. pressure port, separating high-pressure outputs for dual-circuit routing, while a single SAE 3 in. suction port accommodates the combined inlet flow. The version A shaft diameter of 31.75 mm fits standard splined or keyed couplings for torsional load transfer. NBR sealing protects internal clearances from fluid bypass and resists common hydraulic oils, ensuring reliable service life under the stated pressure rating.
