The type PFC 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 PFC fluid coupling is a compact, rugged unit, the major components being aluminum alloy castings. It comprises the basic fluid coupling, diaphragm input mounting and multidisc, semi-flexible coupling on the output side. Bores and keyways may be finished to suit customer's requirements
Fusible plugs are fitted to all but the smaller 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
The type FP fluid coupling is combined with a V-Belt pulley which replaces the pulley usually mounted on a motor shaft in a V-belt drive and can be fitted simply and quickly on new or existing drives. It will give a light load start to a motor, provide smooth controlled acceleration and ensure overload protection for the motor and driven machine.
Using a type FP fluid coupling in place of the standard pulley means it is frequently possible to use a smaller motor, because the fluid coupling allows the motor to run quickly up to speed, where its overload torque may be used to start the driven 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
Fusible plug are fitted to all but the smallest sizes to provide protection against excess temperature rise should the motor overload trip fail to operate during stalled or overload conditions
The type FP fluid coupling can be supplied without the pulley sheave (except sizes 7 & 8) thus allowing the customer to fit his own pulley sheave ( or chain sprocket) if required.
Arrangement for vertical shaft mountings are available.
An important feature of the type FP fluid coupling is that there is no need to dismantle the unit before fitting it to the motor shaft; installation is a simple operation.
Units are available in nine sizes from 0.1 KW to 93 KW.
