Elika Marzocchi Gear Pumps

Elika Marzocchi Gear Pumps are designed to deliver advanced hydraulic performance, significantly reducing operating noise compared to traditional gear pumps. Thanks to the patented helical profile, Elika eliminates fluid encapsulation—one of the main causes of vibration and high noise emissions in hydraulic systems.

The result is an average noise reduction of 15 dBA compared to a conventional external pump, making the Elika series ideal for applications where noise is a critical factor: urban environments, medical equipment, indoor installations, or mobile vehicles.

Range and Compatibility

The Elika range is available in three groups:

• ELI2: 7.0 – 35.1 cm³/rev

• ELI3: 20.4 – 87.1 cm³/rev

• ELI4: 86.5 – 199.8 cm³/rev

Each group is fully geometrically and mechanically compatible with the ALP and GHP series, allowing direct integration into existing systems without major modifications.

High Operating Pressures

Elika pumps can operate at pressures up to 310 bar, thanks to their robust construction and helical gear design, which ensures motion continuity even at low rotational speeds. They are therefore suitable for both high-dynamic applications and prolonged stationary operations with high differential pressures.

Technical Structure and Materials

Each pump is built with:

• Extruded aluminum body

• Hardened and ground steel gears

• Ductile iron flanges and covers

• Axial compensation system integrated into the cover

This special configuration reduces internal leakage and ensures high volumetric efficiency even at low speeds.

Additional Features

• Operating speeds: from 200 to 4000 rpm (ELI2), 3500 rpm (ELI3), 2800 rpm (ELI4)

• Noise level: up to 15 dBA lower than standard pumps

• Available seals: NBR for standard use, VITON® for high temperatures (up to 120 °C)

• Rotation: right-hand or left-hand (non-reversible)

• Mounting: via Oldham couplings, European, SAE or BK flanges, compatible with D or FA** threaded ports

Typical Applications

• Earthmoving and lifting machines

• Continuous cycle industrial presses

• Mobile vehicles, electric buses, lifting platforms

• Medical machinery and quiet electro-hydraulic systems

• Hydraulic actuators for indoor environments
