Comment
Possible modification of installation, replacement pump has compliant connection diameter.
If you are pumping chilled water media or special material requirements, please contact Wilo Technical Inside Sales. Replacement pumps designed for glycolin-infused water (max. 50%) have the -S1 extension and a different part number than standard seal pumps. Always consult Wilo when pumping media other than water.

Glanded pump in close-coupled design with flange connection
Application
For pumping heating water (in accordance with VDI 2035), water-glycol mixtures, cooling water and chilled water without abrasive substances in heating, chilled water and cooling water systems.
Technical data
- Permissible temperature range of -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 3~400 V, 50 Hz (others on request)
- IP rating IP55
- Nominal diameter DN 32 to DN 150
- Max. operating pressure 16 bar (optionally 25 bar on request)
