VCM-SF Series Variable Vane Pump | VCM-SF-15C, 30S, 20-C6, 12C

VCM-SF Series High-Performance Variable Displacement Vane Pumps

Product Overview: The VCM-SF Series stands as a benchmark for “High Efficiency and Low Noise” in industrial hydraulic systems. As a precision pressure-compensated vane pump, it automatically adjusts flow output based on system load demand. This comprehensive range includes core models such as VCM-SF-15C-10, VCM-SF-12C-10, VCM-SF-30S-20, and specialized units like VCM-SF-20-C6-20 and VCM-SF-30D-4CG-30. Utilizing a unique pressure-balanced construction and precision regulator springs, the VCM-SF series de-strokes to near-zero displacement once the set pressure is reached, significantly reducing energy consumption and system heat generation.

Key Technical Advantages:

• Automatic Pressure Compensation: The variable design ensures the pump only delivers flow when required. During pressure-holding, it reduces eccentricity to a minimum, cutting power consumption by over 40% compared to fixed systems.

• Ultimate Silent Performance: Optimized suction port geometry and high-precision vane assemblies ensure that operational noise remains at exceptionally low decibel levels even at its rated 7 MPa pressure.

• Low Temperature Rise Stability: Precision internal clearance compensation minimizes internal leakage and heat. This ensures minimal oil temperature rise during prolonged deadhead cycles, protecting the life of seals and valves.

• Rapid Response Speed: The sensitive variable mechanism reacts instantaneously to actuator movements (e.g., clamping cylinders), ensuring consistent cycle times and stability for CNC equipment.

• Target Applications: CNC lathe clamping systems, automated tapping machines, precision grinding machines, shoemaking machinery, and energy-saving hydraulic power units.
