PVV2-1X/045RB15DMB

The PVV2-1X/045RB15DMB pump belongs to the PV Fixed Displacement Pumps series and is manufactured by Bosch Rexroth. It is intended for hydraulic automation circuits where a constant displacement unit is needed to move oil at predictable rates. The displacement is 45.4 cm³ per revolution, giving a theoretical flow of 66 L/min when the shaft turns at 1500 rpm. A continuous working pressure of 175 bar allows the pump to maintain system load without intermittent relief cycles. Clockwise shaft rotation matches standard right-hand power take-off arrangements. To protect against cavitation, the inlet must not drop below an absolute pressure of 0.83 bar, while the permissible fluid temperature spans –10 to +70 °C so the unit can start in cold environments and run at normal operating heat. The design accepts hydraulic media with viscosities from 13 to 860 mm²/s, letting users run either light mineral oils or heavier blends as required. Installation follows the SAE J744 flange pattern with an SAE-B interface, simplifying alignment on common industrial powerpacks.

The pressure port is sized for a SAE 1-inch fitting, and the suction side uses a larger SAE 1 1/2-inch connection so inlet velocity stays low. Both ports are supplied as SAE flanges secured by UNC screws, making field assembly straightforward with widely available hardware. The maximum permitted absolute inlet pressure is 2.4 bar, a figure that accommodates boosted charge pump arrangements when long suction lines cannot be avoided. Fluid cleanliness must be kept at ISO 4406 code 20/18/15 to prevent premature wear of the internal gear set. The pump weighs 14.8 kg, allowing a single technician to position it without lifting equipment. By combining these interface details with the mounting flange specified earlier, the pump integrates quickly into compact hydraulic power units and maintains leak-free service throughout its service life.
