Detailed Description
DUPLEX INTELLIGENT PUMP CONTROL PANEL FOR SEWAGE LIFTING PUMP, WITH THREE PHASE, AC380V/50HZ
Model L932-S
Eliminates the need for at least 5 water level sensor or 3 float switches: stop-level, normal- level for one pump, high-level for two pumps, overflow-alarm level. Thus significant cost-savings result from dramatically reduced purchasing and clearing of sensors or float switch.
More secure because it uses level transmitter, whereas sensors or float switch often fail because of the effect of sludge.
Different water levels (depth) for starting or stop the pumps can be set via LCD screen directly and real time depth value displaying;
Model L93S-S is specially designed for duplex sewage pumping system, by adopting level transmitter with 0.5-4.5V analog signal, pump user can easily set the different liquid depth for sewage pump operation and observe the dynamic liquid depth in the sump or sewage tank.
Typical usage scenarios include:
-Chemical, petroleum, pharmaceutical, mining, paper making industry
-Cement plant, steel plant, power plant, coal processing industry
-Municipal waste water treatment plants
-Drainage system
-Municipal engineering
-Construction site
Application & Control characteristic:
Connecting 0.5-4.5V level transmitter to replace liquid probe, float switch
Pump start and stop according to different depth value setting
Duplex pump control
Main pump / standby pump automatically alternate
Main pump / standby pump automatically switch against malfunction
Standby pump participate running if more flow coming
