Flexible couplings for fire pump systems

Fire pump engine packages often see the most extreme environmental conditions.

During the design and development phase it is imperative to analyse the system and validate the connection between the internal combustion engine and the driven pump.

Reich has designed a highly torsionally flexible coupling capable of supporting a drive shaft connection for the fire pump industry.

For fire pump applications driven by a combustion engine, a Reich VSK coupling is an integral component for connecting the combustion engine to the right-angle gear drive of the fire pump system.

By using the AC-VSK flexible coupling, the drive train can be protected from dynamic overload, reduce resonance-induced vibratory torques, and provide a convenient connection between the combustion engine and drive shaft.

The couplings are available in nine sizes to cover the complete power range of the fire pump industry.

Once the coupling size has been determined, a torsional vibration analysis is recommended to validate the coupling selection.

If the fire pump system is an electric driven stationary system, the flexible Reich Multi Mont Sella couplings can be installed.

The Multi Mont Sella couplings are also torsionally flexible but designed to provide a shaft to shaft connection between the electric motor and driven equipment.

The Multi Mont Sella couplings are designed to cover a wide power range and provide a simple way to replace the rubber inserts.
