ELIKA is the low-noise, high-efficiency, low-pulsation gear pump developed in close collaboration with the Faculty of Engineering at the University of Bologna through the generation of a dedicated design software.
ELIKA is a solution for all applications requiring low levels of noise and high-levels of efficiency, particularly at low speeds. ELIKA in fact reduces noise emissions by as much as 15 dBA with respect to traditional external gear pumps. Maximum working pressures are similar to those for the GHP series (cast iron/aluminium), thus reaching 300 bar. The particular tooth profile without encapsulation furthermore allows a considerable reduction in pressure oscillations and vibrations transmitted to other components connected to the pump (hoses, tank and valves), producing numerous advantages in the circuit. The helical gear effectively guarantees continuity of movement despite the low number of teeth. The low number of teeth also significantly reduces the fundamental frequencies of noise output, making the sound particularly pleasant.
