Grundfos UP and UPS Circulators

Long life, low noise

The UP(S) pumps can be used in both open and closed systems. 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. UP(S) pumps are designed for 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.
