Low Noise, High Efficiency Gear Pumps - 1

The low noise, low pulsation helical gear pump. Groups 2, 3, 4 and multiple pumps. ELIKA HELICAL GEAR PUMP Quality Products for Mechanical & Fluid Power ELIKA®, Marzocchi's new gear pump is a perfect fit for all applications that require low noise levels. The use of the new ELIKA® gear pump eliminates adverse noise effects on hearing and on the surrounding environment. The ELIKA® range of pumps reduces the noise level by up to 20 dBA (depending of which group of pump) compared with a conventional external gear pump. ELIKA® is a patented produc

an excellence in engineering www.jbj.co.uk/ELIKA_gearpumps.html The helical shape of the patented Elika® profile eliminates the phenomenon of air encapsulation typical of normal gear pumps, curing 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. Internal leakage, laminating from outlet to inlet and overheating the pump components, is virtually eliminated in the Elika® pump...

Low Noise, High Efficiency Gear Pumps - 4

Low Noise, Low Pulsation Gear Pump ELI2 is the first in the ELIKA ® series and includes pumps with displacement from 7 to 35 cm 3/ rev; perfectly interchangeable with the standard gear pumps ALP2 and GHP2 series. The maximum operating pressures are similar to those of GHP2 series and extend up to 300 bar. The helical gear ensures the continuity of flow despite the low number of teeth. The low number of teeth reduces the fundamental frequencies of the pump noise, reducing the noise level by an average of 15 dBA compared with a conventional external gear pump. The particular shape of the...

MARZOCCHI H 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...

Elika Series 2, 3, 4 and Multiple MARZOCCHIPOMPE Installation Notes For best performance and longer life of the Elika® series low noise, low pulsation gear pumps follow the installation and assembly instructions within this catalogue. Some general considerations should be made on the hydraulic system, in which the pump is to be fitted. Special attention should be given to hydraulic system design and assembly, especially to the intake, delivery and return pipes and position of system parts; valves, filters, tanks, heat exchangers and accumulators. Proper safety devices and reliable...

Low Noise, High Efficiency Gear Pumps - 8

Elika® Series 2, 3, 4 and Multiple Low Noise, Low Pulsation Gear Pump Inlet Pressure Under standard working conditions, intake pipe pressure is lower than atmospheric pressure. The operating inlet pressure should range between 0.7 and 3 bar (absolute). Inlet and Delivery Lines Hydraulic system pipes should be installed with no sudden changes of direction, sharp bends and sudden differences in cross-section. They should not be too long or out of proportion. Pipe cross-section should be sized so that fluid velocity does not exceed recommended values. It is advisable to carefully consider the...
