Technical data
* Permitted temperature range of the fluid: -20 °C to +140 °C* Max. ambient temperature 40 °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 3~400 V, 50 Hz (others on request) IP rating IP55 Nominal diameter DN 32 to DN 200 Standard version for operating pressure: 13 bar (up to +140 °C) / 16 bar (up to +120 °C)
Materials
