The PVV42-1X/122-068RA15DDMC pump belongs to the PV Fixed Displacement Pumps series from Bosch Rexroth and supplies constant flow for hydraulic automation. The cover section displaces 67.5 cm³ per revolution, giving predictable volume for ancillary circuits, and reaches 100 L/min at 1500 rpm through a SAE 1-inch pressure port. Installation is handled by flange mounting to SAE J744, with the SAE C (127-2) flange defining the bolt pattern. Clockwise rotation aligns the shaft with standard right-hand prime movers, while a minimum speed of 600 rpm prevents cavitation. The unit is supplied without a through drive, so no additional pump can be stacked in line. NBR seals contain common hydraulic oils, and the 34.5 kg weight requires adequate structural support.
The flange section offers a larger displacement of 121.6 cm³ per revolution to power primary actuators and delivers up to 177 L/min at 1500 rpm when supplied through a SAE 2-inch suction port sized for low inlet velocity. Continuous system operation is permitted at 175 bar, making the pump suitable for medium-pressure machine tools and presses. Shaft speed may rise to 1800 rpm when 1 bar inlet pressure is available, extending compatibility with engines that run at higher governed speeds. Together, the two sections provide fixed-ratio flows that simplify circuit design where separate services require distinct but synchronized outputs.
