The ELIKA® gear pump reduces generated noise levels by an average of 15 dBA compared with conventional external gear pumps. Now the range has been extended to include group 3 and multiple pump formats.
The group II ELI2 is the first in the series of ELIKA range and includes hydraulic gear pumps with displacement from 7 to 35 cm3/rev; perfectly interchangeable with the standard gear pumps ALP2 and GHP2 series.
The maximum operating pressures are similar to those of GHP2 series and extend up to 300 bar. The helical gear ensures the continuity of the motion despite the low number of teeth.
The low number of teeth reduces the fundamental frequencies of the pump noise, producing less sound.
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.
ELI3 is the group III range in the ELIKA® series and includes pumps with displacement from 20.4 to 87.1 cm3/ rev; perfectly interchangeable with the standard gear pumps ALP3 and GHP3 series.
The maximum operating pressures are similar to those of GHP3 series and extend up to 300 bar.
The group 2 ELI2 can now be supplied in multiple format
