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.

ELIKA® Technical Q&A

Q1: What sets ELIKA apart from traditional external gear pumps?
A: ELIKA employs a helical gear tooth profile that ensures continuous engagement, lowering pressure ripple and vibration. Its patented axial compensation system minimizes internal leakage, resulting in higher volumetric efficiency and longer life compared to straight-tooth gear pumps.

Q2: How does ELIKA achieve significant noise reduction?
A: By spreading the load across the helical tooth surface, ELIKA reduces vibration and high-frequency excitation at the source. This translates into noise reductions of up to 20 dBA, a critical advantage in industries such as marine, transport, and food & beverage, where noise control is both a safety and comfort factor.

Q3: What are the pressure and speed capabilities of the ELIKA series?

A: The pumps operate at continuous pressures up to 300 bar (310 bar peak) and maintain efficiency across wide speed ranges, making them suitable for high-demand environments such as offshore oil rigs, wind turbine yaw control, or motorsport actuation systems.

Q4: How does the pump maintain efficiency under varying operating conditions?
A: ELIKA incorporates a patented dynamic compensation system that balances axial forces and reduces leakage. As a result, the pump delivers >90% volumetric efficiency even at low speeds, conserving energy and ensuring reliable operation in renewables, power generation, and environmental handling equipment.

Q5: What displacement and flow options are available?
A:
» ELIKA1P: 2.1 to 8.1 cm³/rev.
» ELIKA2: 7 to 35 cm³/rev.
» ELIKA3: 20.4 to 87.1 cm³/rev.
» ELIKA4: 86.5 to 199.8 cm³/rev.

This range makes ELIKA equally suitable for precision dosing in food processing or heavy-duty lifting in marine and materials handling.

Q6: Can ELIKA be integrated into multi-pump systems?
A: Yes. ELIKA is compatible with a wide range of gear pump families (for example ALP2/GHP2) and can be configured in tandem or multiple combinations, with both clockwise and counterclockwise rotation available. This allows system designers to create complex hydraulic circuits for applications such as power generation skids, offshore platforms, or mobile construction machinery.

Q7: What makes ELIKA suitable for noise-sensitive or precision-critical applications?
A: The low-pressure ripple and reduced acoustic signature improve system stability, protect sensitive actuators, and reduce cavitation risks. This makes ELIKA ideal for motorsport, medical, renewable energy, and food processing, where precision and quiet operation are essential.

Q8: How does ELIKA contribute to energy savings and sustainability?
A: High efficiency across the entire operating range results in reduced energy consumption, lower fluid temperatures, and extended service intervals. These benefits directly support sustainability goals in renewables, transport, and environmentally sensitive industries.

Q9: What industries benefit most from ELIKA technology?
A:
» Power Generation: Reliable hydraulics for turbines, cooling, and auxiliary drives.
» Oil & Gas: High-pressure reliability for offshore and subsea systems.
» Renewables: Silent, efficient hydraulics for wind, solar tracking, and hydro.
» Marine: Comfort and compliance through low-noise operation.
» Motorsport: High-speed, compact pumps for precise actuation.
» Food & Beverage: Quiet, hygienic dosing and processing applications.
» Transport: Low-noise auxiliaries for EVs and hybrid systems.
» Environmental & Materials Handling: Efficient, sustainable lifting and recycling systems.

Q10: What makes ELIKA a future-ready solution?
A: With its broad displacement range, high-pressure rating, energy-efficient design, and compatibility with multiple pump families, ELIKA is a versatile platform that supports both industrial and mobile hydraulic applications, making it a truly future-ready solution for the next generation of hydraulic systems.
