Internal gear pumps are positive displacement devices that convert mechanical power into hydraulic energy. Thanks to their specific design and axial and radial pressure compensation technology, they ensure a continuous, quiet and well-balanced flow, ideal for systems where precision, compactness and low noise levels are required.

The single configuration is the most compact solution in the internal gear pump family: a single pumping stage feeds one delivery line, simplifying the circuit layout and reducing overall dimensions. This type is particularly valued in machine tools, hydraulic presses, lubrication systems, and centralized installations, where constant flow with low noise levels is required.

At Fluid-Hub, you'll find a selection of single internal gear pumps featuring:

• High volumetric efficiency, even at low rotational speeds.

• Good self-priming capability, simplifying system start-up.

• Quiet operation, thanks to the internal meshing profile that reduces pressure pulsations.

• Compact and robust construction, suitable for demanding operating conditions.

• Reversible flow compatibility in selected models, for greater application flexibility.

Explore other gear pump categories and alternatives available on Fluid-Hub:

• Double internal gear pumps: integrate two pumping sections on a single shaft, feeding two independent circuits in parallel from one drive unit, optimising space and cost.

• External gear pumps: ideal for standard low- to medium-pressure applications, with robust construction and competitive pricing.

• Helical gear pumps: appreciated for their excellent low noise and smooth flow output, particularly suited for high-performance mobile and industrial equipment.

To complete your installation, we also offer bell housings and couplings for mechanical connection to the motor and suction filters to protect the pump from fluid contamination at intake.
