Meets global approvals for drinking water
If you require a circulator approved for drinking water applications, the UPS B variant of the large UPS three-speed circulator pump with a bronze pump housing meets these requirements – and it is also suitable for hot water circulation. Used in both open and closed systems, the UPS B is of the canned-rotor type, with the pump and motor forming an integral unit without a shaft seal and only two gaskets for sealing. The bearings are lubricated by the pumped liquid.
The UPS B pump incorporates a thermal overload switch in the stator. If the winding temperature becomes too high, the switch will interrupt the electricity supply either via an internal relay or an external contactor.
