Fire Fighting Systems Component
Flexible Couplings
Selection and supply of flexible input couplings linking diesel engines to fire pumps or transmissions, verified by torsional vibration analysis (TVA) for class approval.
Description
FFS selects and supplies flexible input couplings that link diesel engines to fire pumps or transmissions, addressing torsional vibration and misalignment across the driveline from propulsion systems to Fi-Fi pumps. Selection is verified by torsional vibration analysis (TVA) for class rule compliance.
Coupling types
- Tooth coupling for pumps driven by an electric motor or standalone gearbox
- Flexible resilient coupling (TRI) for flexibly mounted engines
- Flexible fixed coupling (PVN) for rigidly mounted engines
Selection criteria
Engine mounting, available space and PTO design determine the coupling type for each installation.
