Pump media temperature
Pumps have a temperature class as stated on the nameplate. These are based on a maximum ambient of
40 ºC (104 ºF). Refer to Flotronic Pumps if higher ambient temperatures are to be considered.
Where there is any risk of the pump being run for prolonged periods against a closed or partially closed
valve generating high media and casing external surface temperatures, it recommended that users fit an
external surface temperature protection device.
