The PVV41-1X/069-018RA15DDMC pump belongs to the PV Fixed Displacement Pumps series and is manufactured by Bosch Rexroth for constant-flow hydraulic automation. It contains a flange-side displacement of 69.0 cm³ per revolution and a cover-side displacement of 18.0 cm³ per revolution to feed two separate circuits from one housing. At 1500 rpm the flange section delivers 101 l/min while the cover section supplies 26 l/min, providing predictable volume at a standard drive speed. Continuous pressure capability is set at 175 bar on the flange side and 210 bar on the cover side so each outlet can support different load levels. Clockwise rotation matches right-hand prime movers and prevents cross-porting during installation. A maximum speed rating of 1800 rpm keeps the pump within the safe operating envelope of common electric motors.
A cylindrical drive shaft, coded A, simplifies coupling and transmits torque through a 31.75 mm diameter journal. The SAE-C (127-2) mounting flange aligns the housing with standardized bell housings to speed assembly. The flange outlet uses an SAE 1-1/4 in pressure port, and the cover outlet uses an SAE 3/4 in pressure port, allowing separate hose sizes for the two flow rates. A single SAE 3 in suction port feeds both gear sets, reducing inlet restriction and limiting cavitation. Fifteen UNC screws secure the SAE flange ports, creating a rigid connection that resists leakage under rated pressure. The assembled unit weighs 34 kg, a value that determines handling requirements and support hardware during installation.
