TP80-40/4 Shaft Seals Manual

34
Types of shaft seals
Shaft seals
Type H for ø12, ø16 and ø22 mm shaft with SiC/
carbon seal faces
Suitable for use in CR/CRI/CRN pumps, the seal is rec-
ommended for use in very hot water (above 100°C).
Can be replaced without dismantling the pump part.
There is no relation between the indication of suitability
and the pressure-temperature diagram, but together
they form the application profile.
Suitability
Pressure-temperature diagram
The pressure-temperature diagram is based on clean
water. At temperatures below freezing point, the dia-
gram is based on a mixture of water and glycol.
The figures in the following table refer to the pressure-
temperature diagram.
