Oilgear PVK-140 Variable Displacement Hydraulic Pump

Oilgear PVK-140 Variable Displacement Axial Piston Hydraulic Pump is a sturdy, open-loop pump designed to assure high performance where flexibility, flow control, and strength are the keys to the job. Designed into the famous PVK series from Oilgear, this pump is just what industrial and mobile hydraulic systems need when responsive control and dependable performance, combined with adaptability to various fluid conditions, are required.

The PVK-140, with a maximum displacement of 140 cc/rev, offers high hydraulic flow per revolution and thus is apt for systems ranging from medium to heavy capacity. Its variable-displacement design allows output to be modulated according to system demand; this improves energy efficiency, reduces wasted heat, and enhances overall operational control when compared to fixed-displacement pumps. This adaptability will be particularly helpful in applications with fluctuating load requirements where good flow control is of essence.

The pump is designed for open-loop circuit operation, which simplifies system integration and hydraulic layout. It has a strong performance envelope with a maximum continuous pressure rating of 345 bar ≈ 5000 psi and operating speeds of up to 2400 RPM. Combining this pressure capacity with such a high-speed rating means the PVK-140 is ready for demanding hydraulic duties and long operation periods under load without losing stability or efficiency.

This pump provides under rated conditions, such as 1800 RPM and continuous pressure - the PVK-140 produces approximately 63 gallons per minute (≈ 239 litres per minute) of flow, providing dependable and consistent hydraulic output for drives, actuators, power units, and large auxiliary circuits.

Oilgear Series PVK was designed with rugged internal components and sophisticated bearing support for excellent resistance to contamination, thereby helping extend service life. It also supports a wide variety of hydraulic fluids, from low-lubricity to specialty fluids, which provides system designers with flexibility without sacrificing performance. Applications of the PVK-140 include heavy-duty industrial presses, mobile power units, material handling systems, and construction hydraulics machinery.
