PRINCIPLE OF OPERATIONS
The principle of operation of the peristaltic pumps is based on the pressure and subsequent release of the
internal tube by the roller mounted on the roller-holder, which is driven by the motor. The dual action of
pressure and release of the tube generates a suction force along the tube itself which primes the liquid
and guide it to the injection line.
The command is sent to the motor by the electronic unit according to the program, to the detected
measurement and to the absence of alarms / errors.
These pumps are also equipped with a built-in instrument, that detects and manages pH and redox
measurements.
