Fixed displacement vane pumps are a compact, reliable and cost-effective solution for generating constant flow in hydraulic systems. Characterized by a simple yet efficient design, they represent an ideal choice for applications requiring stable performance, low noise levels and good volumetric efficiency, even in continuous duty cycles.

Within a hydraulic system, these pumps perform the crucial function of converting mechanical energy into a constant flow of pressurized fluid, thanks to a rotor equipped with radial vanes sliding inside an eccentric housing. The fixed displacement design ensures predetermined flow rates and operational reliability, minimizing control complexity.

At fluid-hub we offer a complete range of fixed displacement vane pumps, selected to provide long service life, ease of maintenance and compatibility with the main industrial standards.

Our range includes:

• Single vane pumps: ideal for applications with medium-low flow rates and compact dimensions. Excellent for industrial machinery requiring constant flow at low pulsation.

• Double vane pumps: combine two stages on a single shaft to achieve higher flow rates or to feed two separate circuits in parallel. They optimize space while maintaining high efficiency.

• Triple vane pumps: used in complex systems requiring simultaneous multi-supply with differentiated flow rates, while maintaining compactness and reliability.

All models are designed to ensure good wear resistance, with self-compensating vanes and materials selected to withstand demanding conditions. They are compatible with mineral fluids and, on request, with special fluids.

For systems that require adaptive flow control, you can also consider our variable displacement vane pumps.
