The PVB15-RSY-41-C-12 axial piston pump belongs to the PVB Piston Pumps series manufactured by Vickers for controlled hydraulic power in industrial automation. It carries design number 41 and delivers a displacement of 33.0 cm³ per revolution, giving fixed volumetric output suited to medium-duty circuits. The displacement is arranged on one side of center, so swash-plate motion produces flow in a single direction when the shaft rotates. At its rated speed of 1800 rpm the pump supplies 59.4 L/min, supporting actuators that need steady flow rates. Shaft-end viewing confirms clockwise rotation, which determines hose routing and motor selection in a power unit.
Control logic is handled by a pressure compensator with control design number 12; this device reduces swash-plate angle when system pressure approaches the set point to prevent over-pressurization. The unit endures working pressures up to 141 bar and draws 29.4 kW at that pressure and 1800 rpm, matching common electric motor ratings. Acceptable hydraulic fluid viscosity starts at 13 cSt, and ambient operation spans from −20 °C to +70 °C to accommodate indoor or mobile machinery. Sound emission registers 69 dB(A) at 1800 rpm and 140 bar, a level that guides enclosure design and worker protection planning.
