Dosing with double screw pump at Fristam Pumpen

The driving force for the twin screw pumps is provided by Sigma 7 servo motors and the appropriate amplifiers. The rapid-response AC servo drives feature a high resolution (integrated 24-bit absolute encoder) and high dynamism, and are ideal for demanding positioning tasks. They are capable of suppressing vibrations and machine resonance frequencies automatically during operation. They are also designed for a long service life and operate at ambient temperatures of between 0 and 55° C without additional cooling. Thanks to their compact dimensions, they require only a small installation space and are easy to mount on dosing units that are commonly used on the rotary tables in filling systems.
