VB1 Series Variable Vane Pump | VB1-20F-A1, A2, A3 | VB1-24F | Pressure Compensated

VB1 Series High-Performance Variable Displacement Vane Pumps

Product Overview: The VB1 Series variable volume vane pump is the definitive power choice for hydraulic systems prioritizing high energy efficiency and precision control. Featuring a built-in Pressure Compensated mechanism, it instantaneously adjusts flow output to match real-time load requirements. This range highlights core models such as VB1-20F-A1, VB1-20F-A2, VB1-20F-A3 (VB1-20FA3), and higher-flow specifications VB1-24F-A1 and VB1-24F-A2. Utilizing a precision regulation design, the VB1 series automatically minimizes flow once the preset pressure is reached, significantly lowering energy consumption and heat generation.

Key Technical Advantages:

• Automatic Pressure Compensation: Equipped with a highly sensitive internal regulation mechanism. When system pressure reaches the set value, flow automatically drops to a minimum, eliminating overflow heat losses and reducing operating costs.

• Minimal Oil Temperature Rise: By avoiding unnecessary fluid circulation at high pressure, these pumps effectively inhibit oil heat buildup, extending the service life of seals and hydraulic fluid.

• Extreme Silence & High Response: Provides millisecond-level flow switching response. Precision-ground rotor and vane components ensure exceptionally low decibel levels even at high rotational speeds, improving the workshop environment.

• Standard Flange Mounting: Features a compact F (Flange) mounting design that is both robust and easy to integrate, making it the premier choice for CNC machine tools and automated lines.

• Target Applications: CNC machine clamping systems, grinder spindle lubrication, small hydraulic presses, woodworking equipment, and energy-saving hydraulic power units (HPU).
