DAYLIFF DQ circulator pumps are designed for hot water circulation in heating, hot water, cooling or air conditioning applications in open or closed systems. A particular feature of the pump design is that the motors have three speed settings so it is possible to select the ideal flow to meet system requirements.
Pump construction is cast iron pump housing, glass fibre reinforced polypropylene impeller, stainless steel rotor and ceramic bearing support. All pumps are supplied complete with female threaded BSP union connections.
The integral 2-pole asynchronous squirrel-cage motor is designed to operate at three speeds. All motors include an inbuilt capacitor and overload protection and can be connected directly to mains supply through a 5A fuse or MCB.
