MARZOCCHI POMPE S.p.A.ELI2 is the first release of the ELIKAproduct line and includes pumps withdisplacements from 7 to 35 cm 3 /rev;perfectlystandardinterchangeable with ourgear pumps in the ALP2 andGHP2 series.The maximum operatingpressures are similar to those ofGHP2 series and extend up to 300bar. The helical gears ensure the continuityof the motiondespite the low numberof teeth.teeth reduces theThe low number offundamental frequenciesof the pump noise, producing amore pleasant sound. The particularshape of the profile without encapsulationsignificantly reduces pressure-807570[dBA]GHP 2oscillations and vibrations producedby the pump and transmitted to the othercomponents, reducing the noise of thehydraulic system. Axial forces inducedby the helical teeth are optimally balancedin all operating conditions by theaxial compensation system integratedin the pump cover.

Internal leakage,virtually eliminated in the Elika pumps,can overheat the pump’s components.Comparing the characteristics of the Elikapump with other kind of volumetric pumps,it is possible to see that they can be usedin many applications: the rotation speed,work pressure and viscosity range.Comparison of volumetric efficiency at low rotation speed: MarzocchiGHP 2 — ELIKA ELI 2 , displacement 17.8 cm 3 /rev; P = 200 bar.[rpm]4,5004,0003,5003,0002,5002,0001,5001,0005000Ext ernal gearpump & Dualf lank[cSt]10,0001,00010010Work Speed RangePist on pump Int ernal gear Vane pump Screw Pump ELIKA PumppumpWork Viscosity Range1Ext ernal gearpump & Dualf lankPist on pumpInt ernal gearpumpVane pump Screw Pump ELIKA PumpOn side: comparison between the different fields of useof different kinds of volumetric pumps.[bar]400350Work P ressure Range300250200150100500Ext ernal gearpump & Dualf lankPist on pumpInt ernal gearpumpVane pump Screw Pump ELIKA PumpUT-R&D JUL2012 R.53
