Operating Limits
Temperature Limitations
Maximum Fluid and Ambient Operating Temp 203 °F (95 °C)
Minimum Fluid and Ambient Operating Temp -40 °F (-40 °C)
Maximum Ambient Storage Temp 257 °F (125 °C)
Minimum Ambient Storage Temp -40 °F (-40 °C)
* If the intended application fluid temperature exceeds 95 °C, the pump may not
perform as expected.
NOTE: Over-temperature protection — To protect the controller, the motor speed begins to derate when
the internal controller temperature reaches a calibrated threshold. Derated motor operation will continue
until the internal controller temperature drops below a safe value.
