Settima Pump Factory - Innovative Solutions For Reliable Performance

Settima designs and manufactures hydraulic three screw pumps and helical rotor pumps. Since ever, Settima has focused on reducing the noise emissions, both through design choices and through constructive accuracy. This means not only low noise, but also longer lifetime and increased reliability. The Settima pumps are reliable, because they work without producing vibration, ensuring to your applications very long lifetimes. The SETTIMA screw pumps, coupled to electric motors for external or submerged use, are used in a wide range of hydraulic systems by engineers and designers from all around the world. 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. NO NOISE CONTINUUM® CONCEPT 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. THE INNOVATION INSIDE 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. CONTINUUM® VOLUMETRIC EFFICIENCY The volumetric efficiency of Continuum®pumps is depending on both pressure and speed. Continuum® pumps achieve high volumetric efficiencies. Technical Details
