The PVV1-1X/036RA15UMB pump belongs to the PV Fixed Displacement Pumps series produced by Bosch Rexroth for closed-loop hydraulic automation where a constant delivery volume is required. Its nominal displacement of 36.4 cm³ per revolution sets the baseline flow for every turn of the drive shaft. At 1500 rpm the pump reaches a flow rate of 53 l/min, supplying cylinders or motors with a consistent volume stream. Continuous operation is supported at system pressures up to 210 bar, while clockwise rotation ensures the internal gear set is loaded correctly. The pressure port sits on the bottom, 180° from the inlet, simplifying hose routing in compact manifolds. A permissible shaft torque of 250 Nm accommodates standard electric motors, and the assembled unit weighs 12 kg for manageable installation.
Speed limits from 600 rpm to 1800 rpm let the PVV1-1X/036RA15UMB adapt to variable-speed drives without losing volumetric efficiency. An absolute inlet pressure of at least 0.83 bar is required to avoid vapor formation at the suction side. Hydraulic oil temperature must stay between -10 °C and +70 °C so component clearances and lubricity remain stable. The design accepts viscosities down to 13 mm²/s, allowing reliable start-up with warmed low-viscosity fluids. System cleanliness must achieve ISO 4406 code 20/18/15 to prevent abrasive wear on the gears and bearings. NBR sealing elements contain the working fluid and provide compatibility with common mineral-based oils used in industrial hydraulic equipment.
