PEMBRIL CONSTANT FILLING FLUID COUPLINGS
The type FCU fluid coupling when used in conjuction with a fixedspeed 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. See selection chart overleaf.
