inlet pressure
Minimum inlet pressure in relation to liquid temperature:
Sound pressure level: The sound pressure level of the pump is
lower than 43 dB(A).
Ambient temperature: 32°f (0°c) – 104°f (40°c)
Pumped liquids: Water or water Glycol mix.
Liquid temperature: 36°f (2°c) – 230°f (110°c)**

194°f (90°c) 9.2 ft (2.8 m)
230°f (110°c) 36.1 ft (11.0 m)
To avoid condensation in the control box and stator, the
liquid temperature must always be higher than the
ambient temperature.
