Quiet, efficient gear pumps Marzocchi Pompe to the USA marketERT

Italian manufacturer Marzocchi Pompe introduced its new Elika1P gear pump to the US market, during the IFPE ConExpo in Las Vegas, held from 10-14 March. Already presented to the European market at the end of 2019 at CTI Symposium in Berlin, the 1P version combines the advantages of the Elika design in a smaller size displacement, especially suited for applications in the automotive sector.

Elika pumps are suited for applications requiring low noise and high efficiency, particularly at low speeds, developed in close collaboration with the Faculty of Engineering at the University of Bologna. The products reduce noise emissions by as much as 15 dBA compared to traditional external gear pumps. Maximum working pressures of 300 bar are similar to those for the GHP series (cast iron/aluminum). The units have a proprietary tooth profile and housing geometry that considerably reduce pressure oscillations and vibrations transmitted to other components connected to the pump – hoses, tank and valves – producing numerous advantages in the circuit and equipment. The helical gear effectively guarantees continuity of movement despite a low number of teeth. Having fewer teeth also significantly reduces the fundamental frequencies of noise output and results in a more pleasant sound.

Elika gear pumps handle a wide range of rotation speeds, pressures and viscosities, and the pump’s structure minimizes leaks and maximizes volumetric efficiency under all operating conditions. The quiet-running pump is often a better option for applications which currently use more-expensive screw, vane or internal-gear pumps. And it is particularly suited for equipment which uses inverters or variable-speed drives to regulate the speed of actuators.

The company is thus committed to respond to the automotive market demand for increasingly customized solutions, and is focusing a lot in the Elika range, believing it can represent a main driver of growth in the oncoming years. On this purpose, Marzocchi Pompe completed an investment in August 2019 in the new Elika assembly department, with the launch of a new gearing machine programmed for the beginning of 2020, aimed to increase the production capacity of the related gears.
