Oilgear PVM-098 Variable Displacement Axial Piston Hydraulic Pump is a high-capacity, variable-flow solution for the most demanding open-loop hydraulic systems. Being part of the PVM legacy series, this pump is designed to deliver strong flow output with reliable pressure handling, responsive control behavior, and robust construction-making it ideal for industrial machinery, mobile hydraulics, and power units requiring adaptable performance.

With its maximum displacement of 98 cc/rev, the PVM-098 assures substantial hydraulic volume per revolution. It gives it exceptional power for driving larger actuators, material-handling systems, and complex fluid circuits. The variable-displacement design ensures adaptive flow delivery, hence allowing system output to match changing load demands. By this approach, energy efficiency can be enhanced while dissipating less heat compared to fixed-displacement solutions.

It can handle a maximum continuous pressure rating of 260 bar in continuous operation under heavy loads and severe operational conditions. Its open-loop configuration simplifies hydraulic circuit design while maintaining a high level of control and responsiveness. Under normal operating conditions at 1800 RPM and rated pressure, with appropriate inlet conditions, PVM-098 provides approximately 156 litres per minute flow ≈ 41.2 gpm. In fact, such high output makes the pump an excellent choice for medium- to heavy-duty applications like hydraulic presses, big power packs, industrial automation, and mobile machinery where steady and controllable fluid delivery is indispensable.

Engineering by Oilgear ensures that the pump will deliver smooth, efficient performance cycle after cycle. An internal assembly precision-machined for durability, wear resistance, and long service life equips it. Also, the design houses modern hydraulic fluids, including those of lower viscosity or lower lubricity, adding flexibility to systems using specialty or advanced hydraulic media. Despite its high capacity, the PVM-098 remains practical to install and maintain. With strong performance over its variable displacement capability, it is suitable for systems where wide flow needs and quick response are paramount.
