HYDRAULIC PUMPS AND ACCESSORIES

Settima™ Continuum Series Quiet Gear Pump

All Products

Hydraulics

• Special rotors profile avoids oil encapsulation • Average 15dB (A) - less noise compared to standard gear and vane pumps • Extremely low vibrations and pulsations • Very high efficiency for a wide range of speeds (up to 6.500 RPM) • Maximum operating pressure up to 300 bar • Interchangeable with standard gear pumps • No noise Continuum® Technology Settima Meccanica Continuum® represents the no noise alternative to gear and vane pumps to create a better working environment. Products are ideal for high-pressure applications designed with a no noise pump technology capable of eliminating acoustic emissions and vibrations. Advantages
