With microprocessor control for constant speed pumps
With frequency converter control for variable speed pumps
The device is equipped with a manometer and two adjustable differential pressure switches
Traffic
BS 2F Constant speed pumps
Depending on the pressure drop in the system, the pressure switches determine the gradual starting of the pumps, the operation of which is controlled by the microprocessor
BS1V1F Variable speed pumps with one frequency converter
According to the flow requirements, the pumps, one with variable speed and the other with constant speed, are started to provide the required amount of water at a constant pressure
BS2V Variable speed pumps with two frequency converters
According to the flow requirements, the pumps, both with variable speed, are started to provide the required amount of water at a constant pressure
Use
For pumping water from a well or borehole
To increase the pressure of the distribution network (follow local regulations and consult with the owner of the water supply)
