® 3 ELI3 is the group 3 in the ELIKA series and includes pumps with displacement from 20.4 to 87.1 cm / 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 helical gear ensures the continuity of flow despite the low number of teeth. The low number of teeth reduces the fundamental frequencies of the pump noise, reducing the noise level by an average of 15 dBA compared with a conventional external gear pump. ® The particular shape of the patented Elika profile eliminates the phenomenon of air encapsulation typical of normal gear pumps, curing the source of the main cause of noise and vibrations. 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 in the flange and cover, insulated by special gaskets reinforced with anti-extrusion, allow for 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. Back and front plates are of anodized aluminum keeping the unit of low weight but up to the pressure generated. ® ELIKA pumps are available in both uni-directional clockwise or counter clockwise rotation. ® Low Noise, Low Pulsation Gear Pump Elika Series 3 Noise pump comparison [dBA] Marzocchi GHP3 - ELIKA ELI 3, 1500 rpm , same displacement 26.3 cm3/rev, pressure 200 bar.
