UPS pumps constitute a complete range of 3-speed circulator pumps, available both in 50 and 60 Hz.
The pumps can be used in both open and closed systems. UPS pumps are of the 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 the circulation of liquids in heating and air-conditioning systems. Pumps with bronze or stainless steel housings are also suitable for use in hot-water service systems.
