Reduce noise levels by an average of 15 dBA.
Up to 20 dBA depending on pump size.

The helical profile of the gears within the ELIKA^® hydraulic gear pump, reduces pressure oscillations and vibrations produced by the pump, subsequently transmitted to the other components. Less pressure oscillations and vibrations reduces the noise of the hydraulic system.

Axial forces induced by the helical gear teeth are optimally balanced in all operating conditions by the axial compensation system integrated in the pump cover.
Compensation areas in the flange and cover, insulated by special gaskets reinforced with anti-extrusion, allow for fully free axial and radial movement of the bushings, which is proportional to pump operating pressure. In this way, internal leakage is dramatically reduced, ensuring very good volumetric and mechanical pump performances, as well as proper lubrication of the pump’s moving parts.

The low noise  -  high efficiency  -  low pulsation gear pump

reduces noise level by an average of 15 dBA.
‍
Up to 20 dBA depending on size of pump.
‍
Including groups 1, 2, 3 and 4 and also multiple pump combinations.
