VCM Series Variable Vane Pump | VCM-SF-30A/B/C/D, 40A/B/C/D | Low Pressure

VCM-SF Series (30/40) High-Performance Low-Noise Variable Vane Pumps

Product Overview: The VCM-SF Series variable vane pumps are the definitive choice for industrial hydraulic power units prioritizing “Energy Efficiency” and “Quiet Environments.” Featuring a precision pressure compensation mechanism, this series automatically adjusts output flow based on system load demand. This range highlights the comprehensive 30L and 40L displacement lineup, including the top-selling model VCM-SF-30C-20. Utilizing precision-machined internal profiles and a balanced construction, the VCM-SF series maintains exceptional stability under low-pressure conditions while significantly reducing system heat generation by minimizing overflow loss—making it ideal for precision machining and light industrial machinery.

Key Technical Advantages:

• Superior Pressure Compensation: Equipped with a sensitive pressure-sensing mechanism that automatically reduces displacement to near zero when the set pressure is reached, drastically cutting power consumption and oil heating.

• Peak Silent Performance: Optimized 12-vane design and high-precision silencing grooves drastically reduce fluid pulsation and mechanical noise during operation.

• Efficient Thermal Management: Optimized internal circuitry significantly reduces heat generated by internal friction and leakage, extending the service life of hydraulic oil and seals.

• Rapid Dynamic Response: The variable mechanism reacts instantaneously to load changes, providing smooth transitions during actuator reversals for consistent machining accuracy.

• Target Applications: CNC lathe hydraulics, grinding machines, drilling machines, shoe-making machinery, woodworking machinery, and compact hydraulic power units.
