Oilgear PVK-270 Variable Displacement Hydraulic Pump is a high-capacity variable-displacement axial piston pump designed for demanding hydraulic systems with requirements for strong flow, adaptable control, and long-term reliability. Part of Oilgear's legacy PVK series, this open-loop pump provides substantial hydraulic performance for industrial and mobile applications where the stability of output and efficiency of control are indispensable.
The PVK-270 is a high displacement pump, offering 270 cc/rev maximum displacement for lots of fluid volume per revolution - robust flow for big hydraulic circuits and multi-function systems. This makes it ideal for heavy conveyors, material handling systems, power packs, large actuators, and other high-demand fluid power applications where strong, variable output is required.
This series pump provides support for continuous operating pressure in a range from about 301 bar to 400 bar, thereby enabling the sustenance of demanding workloads with steady performances for long duty cycles. Its open-loop design simplifies system layout and reduces control complexity while providing precision response and dependable hydraulic behavior. The PVK-270 is designed for maximum speeds below 1800 RPM, a design that ensures mechanical durability and operation efficiency even when using heavy loads.
Oilgear's PVK series features leading-edge internal design elements, including hardened surfaces, heavy-duty bearings, and effective swashplate controls that increase its resistance to wear, enhance its tolerance to contamination, and extend its service life. These construction qualities allow the PVK-270 to realize consistent performance even in difficult operational environments that fluctuate in pressures or experience long run times.
Oilgear Typical applications include heavy industrial machinery, hydraulic power units, mobile construction equipment, and material handling systems-auxiliary hydraulic circuits in which high output with responsive control is critical. The PVK-270 serves equally well for new system installations or to upgrade existing hydraulics. It provides a reliable balance of flow, pressure, and control flexibility.
