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.
