The PVV41-1X/113-036RA15DDMC pump belongs to the PV Fixed Displacement Pumps series and is built by Bosch Rexroth for constant-volume hydraulic automation. A displacement of 36.4 cm³ per revolution on the cover side delivers a controlled output suited to pilot functions, while 112.7 cm³ per revolution on the flange side serves high-demand actuators from the same housing. At 1,500 rpm these displacements correspond to maximum flows of 53 l/min and 167 l/min, allowing designers to size circuits accurately without external flow dividers. The unit can run up to 1,800 rpm for peak duty or down to 600 rpm for slow cycling equipment, so speed variation still preserves volumetric consistency. A cleanliness class of ISO 4406 20/18/15 limits particulate load in the fluid and protects internal gear faces, and a mass of 34 kg keeps the assembly manageable for frame mounting while providing the rigidity required for continuous service.
Continuous operating pressure reaches 210 bar on the cover side so compact cylinders can generate high forces, whereas 175 bar on the flange side balances output with extended seal life in the larger section. The inlet port accepts absolute pressures between 0.83 bar and 2.4 bar, giving flexibility to mount the reservoir above or below the pump without vapor formation. Fluid temperature can range from –10 °C to +70 °C, which supports cold starts in unheated plants and reliable viscosity control under elevated oil temperatures. The design tolerates viscosities between 13 mm²/s and 860 mm²/s so various hydraulic oils or seasonal grades may be used without harming bearing clearances or volumetric efficiency. These operating windows let the pump integrate into diverse mobile or industrial hydraulic installations without special conditioning equipment.
