SINGLE INTELLIGENT PUMP CONTROL PANEL FOR PRESSURE BOOSTING PUMP, WITH THREE PHASE, AC380V/50HZ
Model L931-B
Model L931-B is specially designed for pressure booster pumping system, by adoption of pressure transmitter (0.5-4.5V), pump user can easily set the different pressure value and observe the dynamic pressure value in the pipeline.
Typical usage scenarios include:
-Houses
-Flats
-Holidays houses
-Farms
-Water supply from wells
-Irrigations of greenhouses, gardens, agriculture
-Rain water reuse
-Industrial plants
-Construction site
Application & Control characteristic:
Connecting 0.5-4.5V pressure transmitter to replace pressure switch
Pump start and stop according to different pressure value setting
