The FlowFlexx range of single, twin and triple pump cold water booster sets utilise quality stainless steel single and multistage end suction pumps with a factory mounted frequency inverter unit for each pump. The speed of each pump is varied by means of the frequency inverter, enabling the pumps to operate in a cascade system. The control of each pump is via a pressure transducer installed in the discharge flow manifold. This relays a 4-20 mA signal to the inverter to vary the motor speed.
FlowFlexx booster sets are available single phase with a low water volt free contact or, three phase incorporating low water, run and common fault volt free contacts. As an optional extra the three phase sets are also available with RS485 connectivity. All units incorporate a high/low pressure alarm, dry run protection, auto change-over, fault history, protection against high/low voltage, over current, current surge, inverter overheat, communication error.
The inverters can be integrated to check on a wide range of parameters including the total accumulated power consumption, the core temperature of the drive and the ambient temperature at the drive.
For example, space or access limitations. In some instances it is possible we can build non-standard booster sets to suit a particular installation. Should this be a consideration then please contact Smedegaard to discuss your requirements.
