Marzocchi Elika helical gear pump — **Marzocchi Elika**Low-noise, low-pulsation helical gear pump, displacements from 7 to 200 cm³/rev.

Interfluid, leveraging its profound knowledge of helical gear pump technology, recognizes and promotes Marzocchi's Elika series as a benchmark in the industry. We have the capability to identify conditions where these pumps are the optimal choice, maximizing performance and efficiency.

Marzocchi's Elika series is a range of low-noise helical gear pumps. Their unique tooth profile without encapsulation significantly reduces both pressure fluctuations and vibrations, ensuring minimal interference with other connected components such as valves, tanks, and hoses. These features make Elika pumps particularly suitable for work environments where minimizing acoustic impact is crucial.

But Elika's excellence doesn't stop here. Compared to other volumetric pumps in the market, Elika offers incredible versatility in terms of speed, pressures, and permissible viscosity ranges. Their unique construction reduces internal leakages, optimizing volumetric efficiency in any situation. Furthermore, thanks to the integrated axial compensation system, they impeccably handle axial forces resulting from the helical teeth, making them ideal for applications with low speeds and high pressures.

With Interfluid by your side, you can be assured of choosing solutions that best suit your needs, making the most of our expertise in helical gear pump technology.

Technical data by series

The Elika series consists of three groups of unidirectional helical gear pumps, right-hand or left-hand rotation. The patented tooth profile avoids trapping and reduces noise and pulsation; an axial compensation system built into the cover balances the axial thrust.

Frequently asked questions

What is the difference between Elika ELI2, ELI3 and ELI4?

They are the three groups of the series: ELI2 from 7.0 to 35.1 cm³/rev up to 4000 rpm, ELI3 from 20.4 to 87.1 cm³/rev up to 3500 rpm, ELI4 from 86.5 to 199.8 cm³/rev up to 2800 rpm. The larger the displacement, the lower the maximum permitted pressure.

What is the maximum pressure of an Elika pump?

It depends on group and displacement. The maximum continuous pressure (P1) is 280 bar for the smaller ELI2 and ELI3 displacements, with a peak (P3) of 310 bar; it drops to 130 bar on the ELI4 of 199.8 cm³/rev. The values for each displacement are in the table.

Is Elika interchangeable with Marzocchi ALP2 and GHP2 pumps?

The Marzocchi catalogue states that Elika pumps are fully interchangeable with the ALP2 and GHP2 series. Before replacement we check displacement, flange, shaft, ports and direction of rotation with you.

Are double or multiple versions available?

Yes, the Elika multiple catalogue covers double and multiple ELI2 pumps, with displacements from 7 to 35 cm³/rev per stage. Interfluid assembles double Elika pumps in-house to customer specification.
