The PVV42-1X/113-055RA15DDMC pump is built by Bosch Rexroth for the PV Fixed Displacement Pumps series. It serves as a dual-stage source of constant flow in hydraulic automation where precise oil delivery is needed. On the cover side the unit offers a displacement of 55.2 cm³ per revolution, and it turns in a clockwise direction to match standard right-hand drive trains. Continuous duty on this stage is supported up to 175 bar, while flow reaches 80 L/min when the shaft runs at 1500 rpm. The pump can operate down to a minimum speed of 600 rpm without loss of lubrication. Mechanical integration is handled through an SAE-C (127-2) mounting flange, and pressure from the cover side leaves through an SAE 1-inch port.
The flange side is sized for larger circuits, providing a displacement of 112.7 cm³ per revolution. It shares the 175 bar continuous pressure rating but delivers up to 167 L/min at 1500 rpm for applications that need higher volume. Shaft velocity may climb to 1800 rpm during intermittent peaks, staying within the specified speed envelope. The general mounting style follows the SAE J744 flange pattern so it aligns with common power take-off interfaces. Pressure on the flange side exits through an SAE 1 1/4-inch connection, while suction for both stages is taken through an SAE 3-inch port. The complete assembly weighs 34.5 kg, which aids stability on skid or reservoir brackets.
