Grundfos Circulator Pump UPS25-60N

Overview
The UPS 25-60 N 180 is a canned rotor-type circulator pump, meaning the pump and motor form an integral unit without a shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid, and the pump includes a 3-step speed selector for optimal performance.

Suitable for
Commercial heating
Domestic hot water recirculation
Grundfos UP, UPS N circulator pumps have a corrosion-free stainless-steel pump housing and are recommended for domestic hot-water recirculation and underfloor heating systems. UP, UPS N can be connected to an on/off time switch to limit pump operation to periods when hot water is usually required.
