Helical gear pump ELI2 multiple

for chemicalsstationarymobile

Marzocchi extends the family ELIKA introducing ELI2 multiple versions. 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. 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. All single and multiple pumps ELIKA are available in both unidirectional rotating right and left, are available all major commercial versions of Group 2 as flanges, shafts and ports. Multiple pumps ELIKA have dimensions similar to the normal Marzocchi multiple pumps.
