Bucher QX internal gear pumps:

ideal for both fixed and variable speed applications

Guaranteed silence, ideal for servo-pump applications

The internal gear pumps are used to operate at a continuous pressure up to 350 bar (depending on the size), they are used mainly in the industrial sector (for example in machines for plastics, die-casting machines, machine tools, presses, etc.) The high yield values related to the compensation system axial or radial allow reaching high efficiencies and a significant reduction of pulsations of pressure and flow. Thanks to special design features and the effective balance of forces, there is a significant reduction of the noise emission levels.
The internal gear pump is characterized by the constant flow rate when the pressure varies. Furthermore, in servo-pump applications, unlike the vane pump, it is often used in a single-stage version with higher performances and efficiency.

The choice of the right internal gear pump can be quite an issue. In such a situation, it is getting more and more important to find a reliable partner that supports you in the in the analysis of the application, providing the best option in term of performance, cost and delivery time.

Interfluid is a highly-specialized engineering sales company that provides value-added services such as consultancy services concerning hydraulic components and systems, technical comparison with more brands, pre and post sales support.
