The PVV41-1X/098-018RA15RLMC pump belongs to the PV Fixed Displacement Pumps series from Bosch Rexroth and provides constant delivery for hydraulic automation where repeatable flow is required each revolution. It rotates clockwise, a configuration that matches most diesel prime movers, and uses an A cylindrical drive shaft that mates with standard couplings. The flange element displaces 97.7 cm³ per revolution and the cover element displaces 18.0 cm³ per revolution, so system designers can obtain two fixed volumes from a single housing. At 1500 rpm these displacements translate to 141 l/min on the flange side and 26 l/min on the cover side, supplying both high and low flow branches without additional pumps. The unit can operate down to 600 rpm, allowing speed-controlled power units to reduce energy consumption during idle cycles while still maintaining lubrication.
Continuous service limits are 175 bar on the flange outlet and 210 bar on the cover outlet, so different circuits may run at separate pressures without exceeding component ratings. The inlet only needs 0.9 bar absolute, which helps prevent cavitation when the reservoir is remote or fluid temperatures are low. Installation is simplified by an SAE-C 127-2 mounting flange, and by distinct pressure ports sized SAE 1 1/4 inch on the flange section and SAE 3/4 inch on the cover section. A SAE 3 inch suction port accommodates the combined flow that enters both pumping groups. NBR sealing is specified for compatibility with conventional hydraulic oils, and the complete assembly weighs 34 kg, a mass that permits handling with common shop cranes during maintenance.
