PV Series Variable Vane Pump | PV201 PV202 PV61 PV62 | PV201R5EF02 PV62R5EC02

The PV Series from LIC Hydraulic is a premier line of Variable Displacement Vane Pumps engineered for medium-to-high pressure industrial circuits. Renowned for their whisper-quiet operation and rapid pressure response, models like the PV201R5EF02 and PV62R5EC02 are designed to automatically adjust flow output to match system demand. This integrated pressure compensation helps minimize energy waste and oil temperature rise. We provide 100% drop-in replacements, matching the exact mounting, shafting, and flow-pressure curves of original Yuken and Parker industrial units.

Technical Highlights

• Model Range: PV61, PV62, PV151, PV152, PV201, PV202.

• Max Pressure: Rated up to $17.5\text{–}21\text{ MPa}$ ($2500\text{–}3000\text{ psi}$).

• Rotation: Available in Right-hand (Clockwise) and Left-hand (Counter-clockwise).

• Compensation: Direct-acting spring-loaded pressure compensator.

Core Advantages

• Ultra-Low Noise Emissions: Vane technology provides much smoother fluid delivery than gear pumps. The PV series is specifically optimized to eliminate the high-frequency “whine,” ensuring compliance with strict environmental noise regulations.

• Instantaneous Response: The high-sensitivity compensator allows the pump to shift from full flow to zero flow in milliseconds, providing stable holding pressure for precision machining operations.

• Energy Efficiency: By eliminating the need for relief valves in pressure-holding states, the PV pump significantly reduces parasitic power loss, leading to a greener and more cost-effective operation.

• Robust Construction: Built with high-tensile cast iron and hardened internal surfaces, these pumps are engineered to withstand the demanding duty cycles of 24/7 manufacturing environments.

Expert Maintenance Tips

• Fluid Viscosity: To ensure the vanes extend correctly via centrifugal force, maintain oil viscosity within the $20\text{–}50\text{ cSt}$ range. Oil that is too thick will cause “vane sticking,” leading to flow fluctuations.

• Air Purging: During initial startup, ensure the pump case is filled and the air is bled from the system. Air pockets in a vane pump will cause “chattering” and can lead to immediate scoring of the cam ring.

• Suction Filtration: Vane pumps have very tight internal clearances. Always use a high-quality 100-mesh suction strainer to prevent large particles from jamming the vanes in the rotor slots.
