SVPF Series Variable Vane Pump | SVPF-12, SVPF-20, SVPF-30, SVPF-40 | Pressure Compensated

SVPF Series High-Performance Variable Displacement Hydraulic Vane Pumps

Product Overview: The SVPF Series variable displacement vane pump is the definitive solution for high-efficiency, energy-saving hydraulic systems. Engineered with a built-in Pressure Compensated mechanism, it instantaneously adjusts flow output based on real-time load demand. This featured range includes the compact SVPF-12, mid-range SVPF-20-55-20 and SVPF-20-35-20T358, and high-flow models SVPF-30 and SVPF-40. Utilizing superior cutoff characteristics, the pump automatically minimizes displacement once the preset pressure is reached, significantly lowering electrical costs and inhibiting system heat—making it a core power source for machine reliability.

Key Technical Advantages:

• Automatic Energy Saving: Features a pressure compensation mechanism. When system pressure reaches the preset limit (e.g., 70 Bar), the pump automatically minimizes flow, eliminating wasted overflow and reducing operational costs.

• Minimal Temperature Rise: By reducing excess flow during standby/deadhead states, it effectively controls system heat buildup, extending seal life and reducing the need for cooling equipment.

• Ultimate Silent Operation: Precision-ground vanes and rotor geometry effectively smooth out pressure pulsations, ensuring exceptionally low decibel levels even under full-load cycles to enhance the workshop environment.

• Rapid Dynamic Response: Provides millisecond-level flow switching, ensuring smooth actuator movement and precise positioning for high-frequency automated cycles.

• Target Applications: CNC cutting machines, specialized grinders, small presses, precision woodworking machinery, injection molding auxiliary circuits, and energy-saving industrial Hydraulic Power Units (HPU).
