Elika gear pumps, available from JBJ Techniques, are suitable for applications that require low noise levels and higher volumetric efficiency. The structure of the pump minimises the internal leakage, maximising the volumetric efficiency under all conditions. This feature makes the Elika pump suitable for work operations with low speed and high pressure. The use of the Elika gear pump eliminates adverse noise effects on hearing and on the surrounding environment, and, according to the company, reduces the noise level by an average of 15dBA compared with a conventional external gear pump. Including group 2, 3 and multiple pumps and the recently released group 4 range.
