The PVQ21-1X/060-027RJ15LDMB pump is produced by Bosch Rexroth within the PV Fixed Displacement Pumps series. It delivers fixed volumes for hydraulic automation where two circuits must be supplied from a single shaft. The flange side provides a displacement of 60.0 cm³ per revolution, allowing it to deliver up to 89 L per minute at 1500 rpm for the primary work functions. The cover side displacement is 27.4 cm³ per revolution, so the secondary circuit receives 39 L per minute at the same speed. Clockwise rotation aligns with standard industrial prime movers and simplifies coupling orientation. A maximum operating pressure of 210 bar lets the unit drive cylinders and motors in medium-pressure machines, while the drive shaft transmits up to 316 Nm of torque without overstress.
Speed capability spans from 600 to 2700 rpm, giving integrators flexibility to match slow idle and full load conditions. Fluid temperature can be as low as -10 °C and as high as +70 °C, enabling use with mineral oils in most ambient environments. Viscosity limits range from 13 to 860 mm² per second, so the pump can handle cold-start oils as well as warmed, low-viscosity fluids. To prevent cavitation, the inlet must be kept above 0.83 bar absolute and must not exceed 2.4 bar absolute. These inlet constraints support reliable suction at every speed setting.
