Ε Unmatched, cushioned soft startflexibility, at an economical price point. Smooth acceleration. Mechanical overload protection. Օ NEW sizes 2760HF & 2870HFoffer higher capacity at higher speeds. Increased starting torqueavailable from standard NEMA B motors with a fluid coupling. This is a benefit not offered by electronic soft start solutions. Օ Proven reliability in demanding applications. No contacting surfaces to wearout Յ virtually no maintenance.Providing the softest, smootheststart will maximize the life of your system components.As the smart alternative toexpensive & complicated...

NEW Longer starting profilesand softer startsՕ For Sizes 1420HF & larger,adjustablemetering orificesregulate the passage of fluid from the delay fill chamber into the working circuit, further softening the start. For sophisticated belt conveyors,consider Type HFDD. The extended delay fill chamber permits initial start factor as low as 40% of the full load torque, dramatically reducing shock & stretch to the belt at startup.Use of the extended delay fillchamber(HFDD) is recommendedfor conveyors subjected to unloaded starts, those with concave sections, those with low inertia, or those with...

Each fluid coupling is shipped with an angle finder. Reorder incase of loss or damage. The angle finder will ease the task of filling the fluid coupling to the specified fill angle. Setup time is reduced, because the angle finder is direct-reading. Simply place the angle finder on the filler plug boss and rotate the coupling to the required fill angle. > Fluid coupling/disc brake packages are versatile designs that can be customized to meet your specific needs. The superior performance inherent in disc brakes, combined with the benefits of a fluid coupling, provide an ideal package for...

The fluid coupling is a multiple use device: > ● Provide soft cushioned starts > ● Provide increased starting torque > ● Provide overload protection Availability Table , Page 15.
