Helical gear pumps are among the most reliable and efficient options for generating hydraulic flow in demanding systems. Thanks to their helical tooth profile, they offer smoother engagement, reduce pressure ripple, and operate with low noise and vibration, making them ideal for high-performance industrial and mobile applications.

These pumps stand out for their high volumetric efficiency, reduced internal leakage, and long operational lifespan. They are particularly suited for continuous-duty cycles and harsh working environments, where robustness and stability are crucial.

Our range includes:

• Single helical gear pumps: a single pumping stage with helical profile, for systems requiring particularly smooth, ultra-low pulsation flow on one delivery line. The ideal configuration when noise reduction and flow quality are top priorities.

• Double helical gear pumps: two independent helical stages on a single shaft, feeding two circuits in parallel while maintaining smoothness and low noise on both lines. Perfect for multi-function systems with strict acoustic requirements.

On fluid-hub you'll also find other gear pump families:

• External gear pumps: the most widely used and cost-effective choice, with robust construction and maximum contamination tolerance. Ideal for simple circuits and applications where cost is a key factor.

• Internal gear pumps: provide excellent flow regularity thanks to rotor-satellite geometry and good self-priming capability. Perfect for precision applications at low rotational speeds.

Helical gear pumps offer the perfect balance of performance, smoothness and reliability, filling the gap between external and internal gear technologies.

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