PUMP The Grundfos UPA mini circulator pumps are designed for
pressure boosting of domestic potable and hot water supplies with
particular applications for showers, taps and water feeds to
appliances. Pumps incorporate a flow switch for automatic on demand
operation. They are for use in open systems and the option of
manual or auto operation can be selected.
Pump construction is stainless steel encapsulated rotor, rotor can
and bearing plate, polycarbonate impeller and cast iron pump
housing. Pumps are supplied with a female threaded BSP union
connection set.
MOTOR
The integral *-pole asychronous squirrel-cage motor includes a
built-in thermal switch which monitors winding temperature and cuts
off the power supply in the event of overload. No remote overload
protection is required, though the pump must be connected to a
suitably rated MCB or fuse.
