The SMART Digital DDA-C is a compact positive-displacement diaphragm dosing pump with variable-speed drive (stepper motor) and intelligent control electronics with minimum energy consumption

the factory-fitted pressure sensor is connected to one of these inputs

Pressure relief valves protect the pump in case of too high counterpressure

start and stop delays

This enables continuously variable control of the motor speed
