Water circulation pumps (water circulating pumps, circulator pumps) are typically used in circuits of heating or cooling installations in the residential and commercial applications, such as power plant, steel factory, air conditioning system.
The circulating pumps are used as centrifugal pumps.
In a centrifugal pump, the power consumed is proportional to the cube of the motor speed, while the flow rate varies in direct proportion to the speed of the pump. This means that if the motor speed, and therefore the flow rate, is reduced by half, the power consumed is reduced to one-eighth. With built-in PID feedback control, V&T EcoDriveCN® AC VFD drives are used to match the speed of a motor with a variable load.
Benefits of utilizing variable speed drives on circulating pumps:
Saves energy,
Extends motor and related machinery life,
More accurate control,
Soft starts, thus decreasing the load on the electrical network of direct starting of motors.
Some competitive advantages:
failure rate < 0.15%, similar as Siemens, Emerson Control Techniques, ABB, Danfoss, Eaton, Schneider, Allen Bradley, Lenze, Yaskawa
