Maximum Recommended Operating Temperature
The maximum recommended operating temperature range is 125°F (52°C). The max-
imum operating temperature is dependent upon the operating pressure. For high
temperature applications, consult the factory for special materials of construction.
The maximum recommended temperature is stated on the pump case. The temper-
ature stated is for the design flow and pressure.
