DQA 25-60 Circulator Pump

DQA 25/60 Circulator Pump is a revolutionary variable speed-controlled circulator pump designed for hot water circulation in heating, cooling, and solar applications. The pump is provided with a number of unique features:

• Variable Speed inverter technology enables the pump to selectively operate on a constant curve, proportional pressure where pressure is adjusted according to system demand, and constant pressure where pressure remains constant irrespective of system demand.
• Three selectable speeds so the pump performance can be matched to system requirements.
• The fully automatic function continuously adjusts pump output to system demand and thus optimizes energy consumption.
• Display indicating power consumption as well as alarm and warning conditions.
• Pump construction is cast iron for the pump housing, stainless steel for the rotor can, and composite plastic for the impeller. Pumps are supplied complete with BSP union connections.

MOTOR

The pump is fitted with an integral synchronous permanent-magnet high-efficiency inverter-controlled motor. The pump should be connected to a suitably rated MCB or fuse.
