Hornet

For slurries and abrasive media

Description

A high performance packing that absorbs

the eccentric action of worn shafts and

bearings. It has a central core of

temperature resistant elastomer. The

square sectioned packing is cross-plaited

with tough aramid fibres at the corners to

resist abrasion and wear. PTFE/graphite

yarn at the centre of each side dissipates

heat and presents a low friction face to

the shaft.

Typical applications

Valves and pumps handling highly

abrasive slurries in pulp and paper mills,

sugar refineries, petrochemical plants,

sewage works, metallurgical plants and

china clay works. Also suitable for

potable water, foodstuffs and steam.
