    One of the most important request from the industrial world is to create a better work environment, which is synonymous of better efficiency, lower cost of production and better quality of life for workers. The reduction of operation noise goes with no doubt toward that direction.

    Hydraulic pumps, above all those for high pressure, entail noise and/or vibration level that are unacceptable for certain new applications. This is the main reason why Settima has designed a new gear pumps generation capable to eliminate acoustic emissions.

    Parameters influencing emissions of hydraulic noise are:
    - cavitation
    - pressure peaks rising from trapping fluid between gear teeth
    - ripple or flow pulsation

    Continuum® (the low noise gear pump) is capable to eliminate these noise causes.


    Internationally patented (patents approved and pending):
    - the rotors profile
    - the screw step
    - the inner force balancing

    The especially studied rotor profile does not trap any fluid volume (no encapsulation chambers).
    The helical course (there is just a single point of contact between rotors) of the Continuum® rotor profile makes a gentle transmission of movement and a minimization of any pulsation. Internal hydrostatic mechanisms are put in place in order to avoid trade-off with efficiency.


    Pulsation is harmful

    - In Hose and Pipe design pressure pulsation is paramount; because pressure pulsation affects the hydraulic system lifetime.
    - Noise is not only generated by the pumps but, in most cases, the systems generate noise by amplifying the ripple. Consequent pressure drops are a noticeable energy consumption and a reduction of overall efficiency.

    Continuum® pump is the right answer to avoid all problems due to system pulsation. The special design of the internal rotors eliminates any cavitation and any pulsation, driving to no noise, long life of the pump and the systems and energy loss reduction.


    The volumetric efficiency of Continuum®pumps is depending on both pressure and speed. Continuum® pumps achieve high volumetric efficiencies.
