- Select coupling size on input power and speed.- The curves show limit capacity of couplings.- If the selection point falls on or close to the max capacity limit line of a given coupling size then it is advisable to check with the

starting time and the maximum allowable temperature calculations.

Fluid couplings are designed for power transmission in high inertia machines operated in difficult operating conditions and exposed to substantial and vehement overload. The application of fluid couplings boosts smooth drive start-up, shortens electric motor operation time at high currents, reduces sudden jerks and halts and stops all dynamic load surpluses.

The couplings can be used in machines intended for operation in underground mines in a, b or c hazard zones with the danger of methane explosion and at level A and B of coal dust explosion risk.

Belt conveyors, scraper conveyors, coal ploughs, crushers, pumps, mills, rotary furnaces, disintegrators, elevators, drawing machines, cable lifts.
