The choice of the most suitable hydraulic pump for an application depends on several factors, including flow rate, pressure, volumetric efficiency and noise level.
On the latter front, Marzocchi's Elika pumps represent an innovative solution for reducing noise in hydraulic systems, thanks to their patented helical toothing which eliminates the phenomenon of encapsulation, the main cause of pulsations and vibrations in traditional gear pumps.
The result is a reduction in the wear of hydraulic components and a reduction in the level of sound emission up to 15 dBA compared to conventional pumps which improves acoustic comfort in the work environment.
Elika multiple pumps: features and benefits
In addition to the standard version, Elika pumps are also available in a multiple configuration, combining two or more stages in a single compact unit. This solution allows you to manage multiple hydraulic circuits simultaneously, optimizing the use of space and improving energy efficiency. Thanks to the possibility of selecting different displacements for each stage, the multiple pump also allows you to adapt the flow rate and pressure to the specific needs of the system, reducing waste and improving system performance.
Marzocchi's Elika Multiple pumps therefore represent an advanced solution for hydraulic systems that require high efficiency, low pulsations and noise reduction and, as anticipated previously, the possibility of combining multiple stages with different displacements in a single compact unit allows:
- managing separate hydraulic circuits with different flow and pressure requirements;
- optimizing overall dimensions and reducing the number of separate components;
- reducing energy consumption, adapting each stage to the specific requirements of the system.
Its characteristics therefore make the Elika pump in multiple configuration a strategic choice in many application areas: from mobile machinery to industrial plants, through the nautical and energy sectors, where quietness and efficiency are essential.
