ELI3 includes pumps with displacements from 20.4 to 87.1 cm3/rev; perfectly interchangeable with our standard gear pumps in the ALP3 and GHP3 series. The maximum operating pressures are similar to those of the GHP series and extend up to 300 bar. The helical gears ensure 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 a more pleasant sound. The particular shape of the profile without encapsulation significantly 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 in the flange and cover, insulated by special gaskets reinforced with anti extrusion, allow for fully free axial and radial movement of the bushings. 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. ELI3 pumps are available in both unidirectional clockwise or counter clockwise rotation. 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.
