The PVB15LSY31C11 pump belongs to the PVB Piston Pumps series and is manufactured by Vickers. Designed for hydraulic automation, it uses an axial piston variable-displacement mechanism that alters output flow by changing the swashplate angle. Each shaft revolution displaces 33.00 cm³, letting system designers calculate precise fluid delivery. At a rated speed of 1800 rpm the pump supplies 59.4 L/min, supporting medium-duty circuits that need steady flow. The same 1800 rpm rating matches common electric motor drives, simplifying power-unit selection. A working limit of 141 bar establishes the maximum continuous pressure the circuit can handle. An SAE mounting flange allows direct attachment to standardized housings, and the SAE Y splined shaft transmits torque without slippage. Anticlockwise rotation must be observed during installation to maintain proper inlet and outlet orientation.
Pump design number 31 identifies the internal configuration used for service parts, while control design number 11 distinguishes the external control package fitted to this model. The installed pressure-compensator control maintains outlet pressure automatically, preventing excessive load on downstream components. Because the displacement zone is limited to one side of center, the unit produces flow in a single direction and avoids reverse swashplate movement. Maximum input power of 29.4 kW demands that the drive motor be sized for peak demand without overload. Acoustic emission measures 69 dB(A) at 1500 rpm and 140 bar, helping engineers meet workplace noise targets. The pump operates in ambient temperatures from −20 °C to +70 °C, covering most mobile and industrial environments. These thermal limits guide enclosure design and fluid selection during system integration.
