ELIKA® Helical Gear Pumps
The low noise, low pulsation, high efficiency gear pump reduces noise level by an average of 15 dBA. Including group 2, 3 and multiple pumps and the latest released group 4 range.
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.
