Profile is everything; the low noise, low pulsation gear pump

The helical profile of the gears reduces pressure-oscillations and vibrations produced by the pump and transmitted to the other components, reducing the noise of the hydraulic system. Axial forces induced by the helical teeth are optimally balanced in all operating conditions by the axial compensation system integrated in the pump cover.

Specific compensation areas into 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 pump''s moving parts.

ELIKA® pumps are available in both uni-directional clockwise or counter clockwise rotation.

ELIKA® series gear pump, low noise, low pressure pulsation.The particular shape of the Elika® profile patented by Marzocchi Pompe, eliminates the phenomenon of encapsulation typical of normal gear pumps, deleting the source of the main cause of noise and vibrations.

The structure of the pump minimizes the internal leakage, maximizing the volumetric efficiency under all conditions.

This feature makes the Elika® hydraulic gear pump suitable for work operations with low speed and high pressure. The internal leakage, virtually eliminated in the Elika® pumps, laminating to outlet from the inlet, overheat the pump components.

Comparing the characteristics of the Elika® with other kind of volumetric pumps, it can be seen that they have a very high field of use like: the rotation speed, work pressure and viscosity range.
