The chart maybe used for selecting a type FCU fluid coupling. It shows maximum operating
power ratings for approved application with direct-on started squirrel cage motors,
and will allow 200% full load torque for starting. Selections may be different from
those shown, for drives having frequent cyclic duty, very high inertia starting,
or diesel engine drives, such cases should be referred to Premium Energy Transmission
Ltd. Office or representative who will prepare specific proposals.
These ratings are also generally suitable for drives employing slip-ring motors;
for drives using DC motors consult Premium Energy Transmission Ltd. Allow for 3 to
5% slip in fluid coupling-low to high loadings.

TYPE FCU SELECTION TABLE
CONSTANT FILLINGS FLUID COUPLINGS
The type FCU fluid coupling when used in conjunction with a fixed speed motor
will give the motor a light-load start, provide smooth acceleration and ensure overload
protection for the motor and driven machine. Using a fluid coupling in the drive-line
often makes its possible to employ a smaller motor, because the fluid coupling will
allow the motor to run quickly up to speed, where its overload capacity may be used
for starting the machine.
Starting or stalling torque may be determined precisely by selection of the initial
oil filling. Further adjustment, to suit drive requirements, may easily be made at
site. The type FCU fluid coupling is a compact, rugged unit, the major components
being aluminium alloy castings. It comprises the basic fluid coupling, diaphragm
input mounting and multidisc type semi-flexible coupling on the output side. Bores
and keyways may be finished to suit customer's requirements.
Fusible plugs are fitted to all except the smaller model fluid couplings to provide
protection against excess temperature rise should the motor overload trip fail to
operate during stall or overload conditions. Vertical applications can be catered
for in most sizes.
Units are available in sixteen sizes, covering ratings from 0.1 kW to 1000kW.
