Low Noise, Low Pulsation Gear Motor Applications www.jbj.co.uk/gear-motors.html #DriveLineHarmony IV The low noise, high efficiency, low pulsation, helical gear motor. Up to 20 dBA noise reduction. ® Marzocchi Elika Motors are built on patented ELIKA Gear Technology, which reduces noise levels by an average of 15 dBA compared to conventional external gear pumps. The use of helical gears ensures smooth, continuous motion even with a reduced number of teeth. This lower tooth count shifts the pump’s fundamental noise frequencies, resulting in a quieter and more pleasant sound profile. The distinctive Elika Profile, patented by Marzocchi Pompe, eliminates the encapsulation phenomenon common in standard gear pumps—removing one of the primary sources of noise and vibration. By minimizing pressure oscillations and vibration transmission to surrounding components, Elika technology significantly lowers the overall noise of the hydraulic system. Additionally, specially designed compensation zones in the flange and cover, insulated by anti-extrusion reinforced gaskets, enable free axial and radial movement of the bushings, further enhancing performance and durability.
