Oilgear PVM-034 Variable Displacement Hydraulic Pump

Oilgear PVM-034 Variable Displacement Hydraulic Pump represents a modern variable-displacement axial-piston pump from Oilgear's legacy PVM line. It features reliable performance, the capability of changing flow rate output, and is applicable to a wide array of hydraulic fluids; thus it is ideal for different hydraulic systems.

With a displacement of 34 cc/rev maximum, PVM-034 has relatively high hydraulic volume per revolution. It is an open-loop circuit design that simplifies the hydraulics layout and makes system integration easier. Continuous pressure up to 260 bar is supported by the pump for handling moderate to demanding hydraulic loads with stable pressure and flow.

The PVM-034 is capable of operating at a maximum speed of 2700 RPM, thereby giving system designers and operators flexibility in matching pump output to machine demands. Under standard conditions — 1800 RPM, rated continuous pressure, and proper inlet conditions — it produces a flow of approximately 53.4 litres per minute (≈ 14.1 gallons per minute). This makes it capable of driving medium-duty hydraulic actuators, auxiliary circuits, mobile hydraulic systems, and industrial machinery that are in need of variable flow and consistent pressure.

The PVM-034 is built with robust materials and surfaces, precision machined pistons, and a well-balanced swashplate design to assure long service life and smooth operation. It is also compatible with modern hydraulic fluids, including those of low lubricity, thereby offering flexibility when using specialty or environmentally-friendly oils.

Since the PVM-034 variable displacement design allows adjustment of output flow against system demand, this pump is ideal for systems where loads fluctuate, where flow requirements alter during operation, or where energy efficiency and fluid economy are of importance. Very suitable for mobile equipment hydraulics, auxiliary power units, compact industrial setups, or applications that require flexible flow control and reliable performance.
