PVB-044-2

The PVB-044-2 pump is part of the PVB Piston Pumps series produced by Vickers for hydraulic automation tasks that require regulated oil flow. It uses an inline variable displacement axial piston design, allowing the swashplate to adjust output without external throttling devices. Displacement is 0.44 in³ per revolution, equal to 7.210 cm³ per revolution, which establishes the fluid volume moved with each shaft turn. A normal operating speed of 8 000 rpm is recommended so the pistons maintain efficiency while component wear stays within limits. Together, these features let the unit deliver controlled flow in compact power packs and mobile machinery.

At full stroke and the 8 000 rpm rating, the pump supplies 15.24 gpm, or 57.68 L/min, giving circuit designers a precise value for sizing conductors and coolers. The maximum outlet pressure of 3 000 psi defines the top load the housing and rotating group can sustain during continuous duty. With a weight of 7.1 lb, the pump can be handled and mounted by a single technician, reducing installation time. These operating figures show the PVB-044-2 can provide reliable flow and pressure in space-restricted hydraulic systems.
