Inlet and exhaust temperatures can exceed 65°C in a fault condition.
In the event of a pump seizure, dust is generated as a result of contact between the rotating and static surfaces.
This dust may contain aluminium sulphate in low concentrations and may be accompanied by a slightly
sulphurous smell.
It is recommended that when dealing with a pump which may have seized you wear gloves, eye protection and
a paper face mask.
