Plate Cooler Pumps

K 14/400 M 1.85 K.W

Applications 
Single impeller centrifugal pump suitable for domestic, civil, industrial and agricultural installations and for decanting, mixing and irrigating uses.

Constructional features of the pump: 
Cast iron pump body and motor support.
Technopolymer or cast iron impeller, as indicated in the table of TECHNICAL DATA.
Carbon/ceramic mechanical seal.

Constructional features of the motor: 
Induction motor, closed and cooled with external ventilation.
Rotor mounted on oversized greased sealed-for-life ball bearings to ensure silent running and long life.
Built-in thermal and current overload protection and a capacitor permanently in circuit in the single-phase version.

Three-phase motors should be protected with a suitable overload protection complying with the regulations in force.
