  • Page 15: Operation

    Installation 5 OPERATION The electric motor transmits power via a reducer, consisting of a pinion (A) and an eccentric crown (B) that drives a connecting cam (C) onto which the diaphragm (D) is screwed. Spring (F) is compressed during the suction cycle, thus storing energy which is released during the discharge cycle. By varying the speed of the motor and depending on the operating mode selected in the Control Unit, the equipment will regulate the flow to the desired value with a maximum variation of 1:3000.
