[%] GHP2 ELI2 [rpm] [cSt] [bar] ® The particular shape of the Elika profile patented by Marzocchi Pompe, eliminates the phenomenon of air 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. ® This feature makes the Elika pump suitable for work operations with low speed and high ® pressure. The internal leakage, virtually eliminated in the Elika range of pumps, laminating to outlet from the inlet, overheat the pump components in other pumps under similar conditions. ® Comparing the characteristics of the Elika with other types of volumetric pumps, it can be seen that they have exceptional operational qualities; the rotation speed, work pressure and viscosity range. Back and front plates are of anodized aluminum keeping the unit of low weight but up to the pressure generated. ® Low Noise, Low Pulsation Gear Pump Elika Series 2 Comparison of volumetric efficiency at low rotation speed: Marzocchi GHP 2 3 ELIKA ELI 2 , displacement 17.8 cm /rev; P = 200 bar.
