Fire systems - end-suction pump, close-coupled or long-coupled

Overview

Overview

The NKF fire system is an NBF or NKF end-suction pump integrated with a coupling and a driver, which may be an electric motor or a diesel engine, assembled on a base frame.

Electric motor

The electric motor is an MG or MMG motor complying with local standards for electric motors. As from 16 July 2011, the motors used in Europe will be IE2 = EFF 1 motors.
