Brochure & Specification SheetsUPS 26-99 SFC
Grundfos UPS N circulator pumps have a corrosion-free stainless-steel pump housing and are recommended for domestic hot-water recirculation and underfloor heating systems. UPS N can be connected to an on/off time switch to limit pump operation to periods when hot water is usually required.
The pump is of the canned rotor type, i.e. pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid. The pump is characterized by:
- Ceramic shaft and radial bearings.
- Carbon axial bearing.
- Stainless steel rotor can and bearing plate.
