2 Safety
All warnings in the manual are summarised in this section.
Pay special attention to the instructions below so that severe personal injury and/or damage to the pump are avoided.
Requirements for measurements on the process media
There are two principles of temperature measurements of the process media:
A. Temperature is measured on the pump outlet side (S1). No equipment with cooling effect on the process media is allowed
between pump and sensor.
B. Temperature is measured somewhere on the pump inlet side (S2). No heat generating equipment is allowed between the
temperature sensor and the pump.

Requirements for measurements on the flush media (double mechanical shaft seal)

Note: Flush media temperature must be measured no more than 2m away from the flush housing outlet.
Pumps mounted with double mechanical shaft seals can operate without the pump casing being liquid filled at all times since the
seal faces are lubricated and cooled by the flush media.
