Product Overview
▔▔The Vickers Variable Vane Pump operates by varying the eccentricity between the pump rotor and the outer cam ring. As pressure builds up in the system to reach the set threshold, a internal spring-loaded compensator piston adjusts the position of the ring relative to the rotor. This shifts the stroke length of the vanes and adjusts the discharge flow rate down to near zero when full pressure is maintained.
Key Advantages
▔▔-
Energy-Efficient Operation: Automatically reduces flow at zero-demand / high-pressure holding stages to eliminate unnecessary energy consumption and system heating.
Exceptionally Low Noise: Intrinsic intravane and precision rotor designs keep acoustic output as low as 62–68 dB(A), meeting stringent modern indoor workplace noise standards.
Versatile Pressure Controls: Compatible with standard pressure compensation, load sensing, dual-pressure regulation, and electro-proportional pressure control.
Compact & High Power Density: High operating pressure capabilities in a compact footprint yield an outstanding power-to-weight ratio.
Long Service Life & Serviceability: Hydraulically balanced design and modular replacement parts make maintenance simple without disturbing system plumbing.

FAQ
▔▔Q1: What is the main difference between a fixed vane pump and a variable vane pump?
A: A fixed vane pump delivers a constant volume of fluid per shaft revolution regardless of system pressure. A variable vane pump automatically adjusts its internal displacement based on pressure demand. When system pressure reaches the compensator setting, flow reduces toward zero, saving power and preventing heat build-up.
Q2: How do I adjust the pressure compensator on a Vickers variable vane pump?
A: Pressure adjustment is made via the compensator adjustment screw located on the pump housing. Turning the screw clockwise increases the cut-off pressure setting, while turning it counterclockwise decreases it. Always verify settings with a pressure gauge installed in the system line.
