Internal gear pumps are volumetric devices that convert mechanical energy into hydraulic power. Thanks to their specific design and axial and radial pressure compensation technology, they provide steady, quiet, and efficient flow, making them ideal for systems that require precision, compact design, and low noise.

At fluid-hub, we offer a selection of internal gear pumps designed to deliver high performance, excellent volumetric efficiency, and long service life even under demanding operating conditions, ideal for industrial systems, mobile machinery, and centralized installations.

In some specific models, internal gear pumps stand out for their ability to handle reversible flow, their compact design, and good self-priming capability.

Our range includes:

• Single internal gear pumps: the most compact configuration, ideal for systems with a single delivery line requiring smooth flow, low pulsation, and quiet operation.

• 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.

You may also be interested in:

• 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.
