The VVS2.50RFPM.30 vane pump is produced by Vickers and belongs to the Vane Pumps series for fixed-displacement hydraulic power generation in automated machinery. Its geometric displacement is 50 cm³ per revolution, defining the theoretical volume delivered to downstream actuators each cycle. The pump is built on frame size 2, so it fits mid-range power units without exceeding common footprint limits. A maximum speed rating of 1800 rpm enables continuous operation on standard electric motor drives used in industrial automation. Right-hand clockwise rotation matches conventional shaft coupling layouts and simplifies alignment with prime movers. The unit mounts on an ISO 3019/2 flange, allowing direct interchange with other compliant pumps during system upgrades. Port connections use an SAE four-bolt flange, which supports rigid, leak-free pipe joints in high-vibration applications. Buna-N seals are employed to resist swelling in petroleum-based fluids and maintain service life under typical plant temperatures. HM hydraulic oil according to ISO 6743/4 is the specified working fluid, ensuring the vane bearings receive proper lubrication and anti-wear additives.
An actual displacement of 51 cm³ per revolution confirms the delivered volume under running clearances, providing predictable flow calculations for circuit designers. Inlet pressure must stay between 0.8 and 1.5 bar absolute so the vanes remain fully flooded without cavitation during high-demand cycles. A maximum working pressure of 100 bar allows the pump to supply moderate force to cylinders and hydraulic motors common in material-handling equipment. Case drain pressure is limited to 1 bar to prevent excessive load on shaft seals and avoid internal leakage paths. The manufacturer specifies an operating viscosity window from 22 to 68 mm²/s to maintain film strength while minimizing internal friction. Staying within this viscosity range also keeps internal vane tips lubricated and prevents overheating at high shaft speeds. Together with the mounting and port standards noted earlier, these pressure and viscosity limits outline the service envelope for safe installation in automated production lines. By adhering to the stated flow, pressure, and fluid requirements, the pump supplies consistent hydraulic energy without frequent maintenance interruptions.
