The PVQ21-1X/045-046RJ15LDMB pump is produced by Bosch Rexroth as part of the PV Fixed Displacement Pumps series and is intended to provide steady oil delivery in hydraulic automation circuits. It is configured for clockwise rotation, matching systems where shaft direction is preset. The cover side displacement is rated at 45.9 cm³ per revolution, and this section supports a continuous pressure of 140 bar. At 1,500 rpm the cover section supplies up to 70 l/min through a 3/4 in SAE pressure port, giving predictable flow for actuators. Mechanical attachment is handled by an SAE-B (101-2) mounting flange, while overall interface geometry follows the SAE J744 standard so it fits common power-take-off pads. These characteristics allow the pump to integrate into fixed-speed drives without external compensation devices.
The flange side displacement is 45.4 cm³ per revolution and can be operated continuously at 210 bar for higher pressure branches in the same installation. Under the same 1,500 rpm condition this section delivers 66 l/min through a 1 in SAE pressure port. Suction is drawn through a 2 1/2 in SAE inlet secured by 1/2-13 UNC-2B fixing threads, maintaining a rigid connection to the reservoir piping. Sealing surfaces use NBR material to resist typical mineral oils, and the assembled unit weighs 20 kg, permitting direct mounting on gearboxes or motor bell housings without additional supports.
