The UPS range of 3-speed circulator pumps are available in two sizes. These pumps can be used in both open and closed systems and are a canned-rotor type, i.e. 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.

UPS pumps are designed for circulation of liquids in heating and air-conditioning systems. Typical applications include one and two-pipe heating systems, under floor heating systems, solar heating systems and more.
