HIGH TEMPERATURE INSTALLATIONS 
 

In situations where the temperature of the fluid to be pumped is likely to exceed 80°C, a high temperature pump code must be specified. This 
is signified using an ‘X’ in the last part of the pump code as shown. 
 
“XTS” in place of “TTS”. Reference Pump Code matrix on page 6 
This indicates the following specification amendments :- 
All seals and o-rings will be changed from Buna-N to Viton. Any gaskets will be changed to a higher temperature spec. Diaphragm shaft 
bushes will be changed from plastic to metal, back-up diaphragms and any bumpstops will be changed to Viton. 
Refer to main table on page 8 for quantities / pump.

Submerged Installation 

Exhaust Safety :- 

When a diaphragm fails during operation, pumped liquid can enter and contaminate the air side of the pump. If diaphragm failure is not 
severe, i.e. a small split or hole, then the pump can continue to run, with air being forced into the product being pumped. If however the 
failure is more serious, then the pump may stop, with fluid or fumes being expelled through the exhaust. Under these conditions it is 
recommended that the exhaust is piped away to a safe area. In standard suction lift conditions this can simply be done by piping from the 
exhaust connection to a safe area. Multiple installations can be piped to a common connection, then to a safe area. In flooded suction 
conditions the exhaust must be taken to a point higher than the fluid level to prevent any siphoning away. In submerged conditions ensure 
exhaust is piped away above fluid level. 
In all conditions ensure exhaust outlet is not expelling across a non-conductive surface. The exhaust must not be placed less than 100mm 
from any non-conductive surface, as this may generate a propagating brush discharge resulting in a possible ignition source.
