The PVV52-1X/193-040RA15DUMC pump belongs to the PV Fixed Displacement Pumps series from Bosch Rexroth and is intended to supply constant flow in hydraulic automation loops. Stage 1 delivers 193.4 cm³ per revolution, while stage 2 moves 40.1 cm³ per revolution, so the two-stage arrangement supports combined circuits that need different flow rates. Clockwise rotation defines the drive direction for coupling alignment, and continuous service is permitted up to 175 bar. The unit can run at speeds as low as 600 min⁻¹, which helps equipment start smoothly without cavitation. A SAE J744 flange provides the mounting interface for direct attachment to power take-offs or motor adapters, and the overall assembly weight is 46 kg.
Hydraulic lines fasten with SAE flanges and UNC screws, simplifying pipe connections across standard manifolds. The cover side pressure port is sized SAE 1 in and sits on the bottom of the housing, whereas the flange side pressure port is SAE 1 1⁄2 in and is located on the top to streamline vertical routing. An NBR seal set contains the operating fluid and withstands petroleum-based oils common in industrial machines. A SAE 3 1⁄2 in suction connection supplies the inlet path so the pump remains fully charged at all duty points, and this arrangement aligns with the discharge ports to minimize installation complexity.
