Motor protection
The pump requires no external
motor protection.
Enclosure class
Indoor use only, IP42. CSA
enclosure type 2.
Insulation class F
Relative humidity Maximum 95 %
Max. outlet pressure 150 psi (10.34 bar)
Sound pressure level 43 dB (A)
Ambient temperature 34 to 104 °F (1 to 40 °C)
Inlet pressure
Liquid temperature Min. inlet pressure
167 °F (75 °C) 0.75 psi (0.05 bar)
194 °F (90 °C) 4.06 psi (0.28 bar)
230 °F (110 °C) 15.7 psi (1.08 bar)
Liquid temperature
36 °F (2 °C) to 230 °F (110 °C)
In domestic hot water systems, keep the liquid
temperature below 149 °F (65 °C) to eliminate the risk of
lime precipitation.
To avoid condensation in the control box and stator, the liquid
temperature must always be higher than the ambient temperature.
