Calpeda 2-NM, NMD pressure booster set with 2 centrifugal pumps

Switchboard

• 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)

Engine
