The best match of low-noise and high-efficiency! The helical 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. The structure of the pump minimizes the internal leakage, maximizing 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. 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. Available from jbj Techniques 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.
