Oilgear PVK-370 Variable Displacement Axial Piston Hydraulic Pump has been designed for heavy-duty applications. This open-loop piston pump has been developed for use in industrial and mobile applications that require a certain flow rate. Although this series of oilgear pumps has been around for a long time, this particular model, which has a high flow rate, represents one of the largest models in the series.
Oilgear PVK-370 has a displacement of a maximum of 370 cc per revolution. This translates to a high flow rate of the hydraulic fluid per revolution, which ensures that there is a high degree of fluid delivery, and this is a characteristic that ensures that there are high capacities in a circuit. The design of this valve offers flexibility in terms of flow rate.
The pump design suits open-loop hydraulic circuits, which ensures ease of integration and control. The product has a continuous working pressure of roughly 283 bar (about 4100 psi) and a peak of 400 bar (about 5800 psi), providing sufficient robustness for heavy-duty operation. The suggested operational speed for this product does not exceed 1500 RPM, which ensures that it operates with better mechanical robustness.
Oilgear PVK-370, with normal rated operation, provides high flow of about 135 gallons per minute, which translates to a flow of about 512 liters a minute. This can be effective for heavy industrial presses, large mobile equipment, complex fluid circuits that require control, as well as hydraulic power units.
The internal design of the PVK series features enhanced durability features like hardened swashplates, robust bearings, and a silent valve plate. These features make it able to run with low-viscosity fluids as well as in situations where it has to work in conditions of low pressures. The use of a high displacement, high pressure, and adjustable output in the PVK-370 makes it reliable for heavy industrial, marine, mining, and construction hydraulics.
