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.
