Marzocchi Pompe
Elika Helical Pumps
Extremely quiet operation and high pressure for noise-sensitive environments and critical applications
Fluid System is an authorised distributor of Marzocchi Pompe Elika helical pumps (hydraulic gear pumps with helical teeth, also often searched as quiet hydraulic pumps), an innovative technology based on a geometry that ensures a significant reduction in noise and flow pulsation. Designed for applications where acoustic impact is a critical factor, Elika pumps offer high volumetric efficiency and consistent performance across a medium-to-high pressure range.
Thanks to their special configuration, Elika pumps reduce noise by up to 15 dBA compared with traditional gear pumps. Their extremely quiet operation, combined with consistent efficiency even at low speeds (thanks to axial compensation), makes them ideal for high-power systems, enclosed working environments and applications requiring smooth, precise hydraulic power delivery in industrial hydraulic systems and noise-sensitive hydraulic applications.
TECHNICAL FEATURES
External gear pumps with innovative helical-tooth design to minimise flow pulsation and noise.
Noise reduction of up to 15 dBA compared with standard gear pumps.
Operating pressure up to 310 bar for intensive hydraulic circuits.
High volumetric efficiency even at low speeds, ensured by axial compensation.
Flow range in Groups 2 and 3, from 7 to 87 cm³/rev.
Modularity with coupling kits for multiple configurations.
Robust construction with aluminium body and hardened steel gears.

FAQ - Helical Hydraulic Pumps
Quiet operation is essential in environments where noise affects comfort, safety or regulatory compliance. Typical examples include lifts in residential buildings, operating machinery in enclosed environments (workshops, “clean” factories), presses located close to operators, and any application in sectors such as marine or medical.
As well as reducing noise, helical teeth drastically reduce flow pulsation. This results in smoother, more stable operation of the entire hydraulic system, lower stress on components and a potentially longer service life for the system.
Yes. Thanks to the modularity of the Marzocchi range, Elika pumps are compatible with coupling kits for multiple pumps. They can therefore be easily combined with one another or with pumps based on different technologies (e.g. standard external gear pumps) to create compact solutions capable of supplying independent circuits.
