Application: Control&Protect Single phase Pump for pressure boosting, DOL

Intelligent pump controller L922-B is an easy to use, programmable controlling & protection device for duplex booster pump.

Model L922-B is specially designed for pressure booster pumping system by adopting pressure transmitter (0.5-4.5v), pump user can easily set the different pressure value and observe the dynamic pressure value in the pipeline.

Main Spec:
Rated Inupt Voltage: AC 220V/50HZ, Single Phase
Rated Output Power: 0.37-2.2kw/3kw-4kw

Main features:
-Double pumps control
Main pump/standby pump automatically alternate
Main pumps/standby pump automatically switch against malfunctions
Standby pump participate running if required.
-Present pressure transmitter with 0.5-4.5v analog signal
-Easily setting the different pressure value and observing the dynamic pressure value
-Eliminates the pressure switch: Pressure setting for two pumps; Pressure setting for one pump
-Automatically stop the pump in the case of water shortage, protecting it from drying running without installing the float switch or liquid probe in the well.
-Auto / Manual switch
