-
- Permitted temperature range of the fluid: -20 °C to +140 °C
- Mechanical seal for pumping water up to Tmax = +140 °C. Up to T ≤ +40 °C, a glycol admixture of 20 % to 40 % by volume is permissible. An alternative mechanical seal must be provided for water-glycol mixtures with a glycol content of > 40% to max. 50% by volume and a fluid temperature of > +40 °C to max. +120 °C or other fluids that differ from water. When using water-glycol mixtures, the use of an S1 variant with a corresponding mechanical seal is generally recommended.
- Mains connection:
- 3~440 V ±10 %, 50/60 Hz
- 3~400 V ±10 %, 50/60 Hz
- 3~380 V -5% +10%, 50/60 Hz
Compliance with electromagnetic compatibility without additional measures:
-
- Interference emission for residential environment according to EN 61800-3:2018
- Interference immunity for industrial environments according to EN 61800-3:2018
- Protection class IP55
- Nominal diameter DN 40 to DN 200
- Max. operating pressure 16 bar up to +120 °C, 13 bar up to +140 °C
