CONSTRUCTION FEATURES OF THE PUMP
Centrifugal multi-impeller pump KVC, intake and delivery manifolds in AISI 304 stainless steel, ball valves with suction and delivery union and delivery check valves in each pump, AISI 304 stainless steel caps.

CONSTRUCTION FEATURES OF THE MOTOR
Air-cooled asynchronous motor, AISI 303 stainless steel motor shaft.

CONSTRUCTION FEATURES OF THE ELECTRONIC
Active Driver Plus is a variable frequency drive for controlling pressurization pumps. It is able to maintain constant water pressure.
The display facilitates the control and the selection of the operating parameters also through a guided procedure of first start (wizard) during which the user is guided step by step in the insertion of the operating parameters.
The variable frequency drive allows energy saving and water hammer protection. Inside the body there are a pressure sensor, a flow switch and a non-return valve.
Integrated thermo-amperometric protection against abnormal voltages, overtemperature and frost. In groups, the second and third pumps are started in cascade, when the first pump reaches the maximum rotation speed.
The pressure is adjustable by the user. It is possible to set working times for each pump with exchange of operation after the set time.
The display shows: operating frequency, instantaneous pressure, current consumption, operating alarms.
Suction port of 1 1/4" male, delivery port 1 1/2" female.
