ELIKA® Helical Gear Pumps

The low noise  -  high efficiency  -  low pulsation gear pump

reduces noise level by an average of 15 dBA.

Up to 20 dBA depending on size of pump.

Including groups 1, 2, 3 and 4 and also multiple pump combinations.

ELIKA®, Marzocchi's low noise, high efficiency, low pulsation, hydraulic helical gear pump is a perfect fit for all applications that require low noise levels.

The ELIKA® gear pump reduces the noise level by an average of 15 dBA compared with a conventional external gear pump. By as much as 20 dBA depending on the size of pump.

The lower frequency of the ELIKA pump produces a quieter sound.

and the ELIKA helical gear pump.
Pressure 200 bar, rotation speed 1500 rpm.

The low pulsation reduces vibration in systems.
This results in less required investment in additional damping components.

Serene Efficiency:

Manufactured by Italian high pressure gear pumps and motors specialist Marzocchi Pompe, the original product group in the ELIKA series are the ELI2 hydraulic gear pump range with displacements from 7 to 35 cm3/rev and maximum operating pressures up to 300 bar. The ELI2 pumps are drop-in replacements for standard gear pumps such as the ALP2 and GHP2, when applications require reduced noise levels.

Tandem and multiple pumps also available where requirement consists of two or more gear pumps mounted on a common drive shaft. Hydraulically, the multiple pumps operate independently and can be supplied with intermediate sealing if the requirement is for each section to deliver different fluids. The larger pump of the combination is normally sited at the shaft end (the drive side).

The reduced noise comes by virtue of fewer gear teeth and the helical gear design ensures continuity of motion. The low number of teeth reduces the fundamental frequencies of the pump noise, so producing less sound. The helical profile of the gears ensures low pulsation and vibration, thereby protecting sensitive equipment such as filter elements, cooler matrix etc.

Axial forces induced by the helical teeth are optimally balanced in all operating conditions by the axial compensation system integrated in the flange and pump cover. Insulated by special gaskets reinforced with anti-extrusion seals, this compensation system allows for fully free axial and radial movement of the bushes, which is proportional to pump operating pressure. In this way, internal leakage is dramatically reduced, ensuring excellent volumetric and mechanical pump efficiencies, as well as proper lubrication of pump's moving parts.

The lower noise produced is a major benefit under modern day health and safety guidelines and the lower pulsation and vibration values result in the need for fewer damping components within any system, saving costs and required space for the complete system.

The Elika pump range has now been extended to include groups 1, 1P, 2, 3 and 4 gear pumps with displacements from 2.1 cm3/rev up to 199.8 cm3/rev. with the possibility to build all groups into multiple form. ELI4 + ELI3 + ELI2 etc. The complete Elika range are directly interchangeable both in form and fit to the popular ALP & GHP series of Marzocchi external gear pumps. ELIKA pumps are available in both uni-directional clockwise or anti-clockwise rotation.

A new helical gear fluid transfer pump based on the ELIKA technology is also available.
