ELIKA ELI2 Multiple Series Pumps
Double Pumps and Multiple Pumps, 7 – 35 cm³/rev.
ELIKA, being low-noise and low-ripple, ELI2 Multiple Series Gear Pumps is a perfect fit for all those applications that require low noise levels. The use of ELIKA gear pump eliminates adverse noise effects on humans and on the surrounding environment.
The ELIKA reduces the noise level by an average of 15 dBA compared with a conventional external gear pump. ELIKA is a patented product. Marzocchi extends the ELIKA family introducing multiple versions ELI2. ELI2 series, displacement from 7 to 35 cm3/rev.
The family extends ELIKA by introducing ELI2 multiple versions. The particular shape of the Elika profile eliminates the phenomenon of encapsulation typical of normal gear pumps, deleting 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. 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.
