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)**

To avoid condensation in the control box and stator, the

liquid temperature must always be higher than the

ambient temperature.
