Key to reading

Technical data

         ·Permissible temperature range from -20 °C to +140 °C

         ·Minimum Efficiency Index (MEI) ≥ 0.4

         ·Mechanical seal for pumping water up to Tmax. = +140 °C. For temperatures up to T ≤ +40 °C, the addition of 20 % – 40 % volume of glycol is permitted. An alternative mechanical seal must be provided with water/glycol mixtures with glycol parts > 40% up to max. 50% by volume and a medium temperature > +40 °C to max. +120 °C or with media other than water. When using water/glycol mixtures, it is generally recommended to use an S1 variant with a corresponding mechanical seal.

         ·Mains power supply

or    3~440 V -5 % +10 %, 50/60 Hz

or    3~400 V ±10 %, 50/60 Hz

or    3~380 V -5 % +10 %, 50/60 Hz

         ·Compliance with electromagnetic compatibility without additional measures:

or    Electromagnetic interference emission for residential environments according to EN 61800-3:2018

or    Interference immunity for industrial environments according to EN 61800-3:2018

         ·IP55 rating
