The PVQ4-1X/069R pump belongs to the PV Fixed Displacement Pumps series and is produced by Bosch Rexroth for closed-loop hydraulic automation. With a nominal displacement of 69.0 cm³ per revolution, the unit delivers a steady volume of fluid each cycle. When driven at 1500 rpm with an oil viscosity of 25 mm²/s, it provides a flow of 101 l/min to feed medium-capacity circuits. Continuous outlet pressure is limited to 210 bar, so internal components are sized for sustained load. The pump must turn clockwise and uses a direct, co-axial drive to couple rigidly to the prime mover. Required shaft speed starts at 600 min⁻¹, allowing low-speed operation without cavitation. HLP mineral oil defined by DIN 51524-2 is the designated pressure fluid to match seal materials. The complete assembly weighs 23 kg, which permits single-person handling during installation.
Hydraulic cleanliness is specified at ISO 4406 class 20/18/15, so filtration must remove particles above that level before the inlet. Suction and discharge orientation remain unchanged regardless of shaft rotation, simplifying hose routing on equipment where the drive direction may vary. The housing can be installed in any position, offering layout flexibility in crowded power units. Minimum absolute inlet pressure is 0.9 bar to prevent vapor formation under full load. A SAE J744 flange secures the mounting interface, while process lines attach by SAE UNC flanges for consistent pipe connections. Short overloads of up to 0.5 s are permitted, protecting the unit from brief pressure spikes. The design excludes a through drive, so no secondary pump can be added in series. These characteristics define the operating limits and connection features required for reliable service.
