Watson-Marlow 120 IP31 pumps: general information 6
If hazardous fluids are to be pumped, safety proce-
dures specific to the particular fluid and application
must be put in place to protect against injury to per-
sons.
The exterior surfaces of the pump may get warm
during operation. Do not take hold of the pump
