Oilgear PVWW-034 Variable Displacement Hydraulic Pump features high-quality performance with a variable displacement, fixed orientation, and a fixed piston count in an axial piston pump. This product is designed for use with open-loop hydraulic systems that employ either hydraulic fluid or low lubricity fluids. The device’s property of working with ultra-low lubricity fluids has been a major factor in it being widely used in environmentally conscious hydraulic systems.

The pump has a displacement of 34 cc per revolution, hence ideal for medium-duty hydraulic systems that require a certain flow of oil. To cater to various hydraulic needs, oilgear has utilized a variable displacement for PVWW-034, which ensures that it adjusts the rate of flow corresponding to the operating requirements. This enhances energy efficiency, reduces heating, and ensures that it operates under a constant load.

Designed for robust performance, the PVWW-034 is able to sustain a continuous pressure of 206.9 bar, with a peak of 241.4 bar. This ensures that this device has all it takes to withstand heavy-duty cycles, as well as peak pressures that are mostly experienced in heavy-duty industrial equipment. Operating at 1800 RPM, this device has a flow rate of 12.7 gpm, with a corresponding rate of 48.1 l/min when working under normal conditions.

The PVWW-034 also features a maximum operating speed of 1800 RPM, which ensures a good balance between performance and long-term reliability. To increase durability when working with water-glycol and other low viscosity fluids, this motor has hardened internal components and bearings that are lined with polymers. Additionally, it has port entries that are accessible from the top, bottom, and back.

Thanks to a perfectly matched compatibility range, high pressure, and a regulable flow rate, the Oilgear PVWW-034 has been found ideally suited for use in hydraulic systems where a perfect functional performance with a smooth operation factor constitutes a priority. At Rexton Hydraulic, we are experts in providing a comprehensive range of PVWW pumps from various models.
