Including group 2,3 and multiple pumps. Group 4 available soon
The helical shape of the patented Elika® gear profile eliminates the phenomenon of air encapsulation typical of normal gear pumps, curing the source of the main cause of noise and vibrations.
The structure of the pump minimises the internal leakage, maximising the volumetric efficiency under all conditions. This feature makes the Elika® pump suitable for work operations with low speed and high pressure. Internal leakage, laminating from outlet to inlet and overheating the pump components, is virtually eliminated in the Elika® pump range.
Comparing the characteristics of the Elika® pump range to other volumetric pumps, it can be seen that, due to the wide rotational speed range, large working pressure and viscosity bands, Elika® is suitable for a wide range of applications. The Elika® range includes group 2, 3 and 4, and also multiple pumps.
The helical gear ensures continuity of motion despite the low number of teeth. The low number of teeth and shape of the profile significantly reduces pressure-oscillations and vibrations during operation from being 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 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 moving parts.
The ELIKA® gear pump reduces the noise level up to 20 dBA compared with a conventional external gear pump. The larger the pump the quieter it is compared to the equivalent standard gear pump.
