Helical gear pump ELI2 series

for chemicalsstationarymobile

ELI2 is the first release of the ELIKA product line and includes pumps with displacements from 7 to 35 cm 3 /rev; perfectly interchangeable with our standard gear pumps in the ALP2 and GHP2 series. The maximum operating pressures are similar to those of the GHP2 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. ELIKA pumps are available in both unidirectional clockwise or counter clockwise rotation.
