Normal demand
Pressure in the pipeline is lower than the setting of pressure switch B, control box will order single pump to run; pressure in the
pipeline reaches the setting of pressure switch B, single pump stops running; control box will alternate double pumps running
automatically when pressure in the pipeline varies in the range of pressure switch B
Extra demand
Single pump is running, pressure in the pipeline still decrease to the setting of pressure switch A, control box will order another
pump to run simultaneously, till pressure in the pipeline reaches the setting of pressure switch B, double pumps will not stop
running; Note: pressure switch should be N/C, close on pressure drop.
Note: Pressure switch A = Low Pressure Switch, Pressure switch B = High Pressure Switch
