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

Products Brief :

L932 is applied for automatic liquid level control / pressure control and effective protection for duplex pumps of with AC380V, 50hz, single phase output power 0.75KW-15KW (1HP-20HP),direct start, including stainless steel or cast iron submersible pump,centrifugal pump, sewage pump etc.
Model L932 has many operation modes by adopting different electric installations. An important feature that makes the difference between Model L932 and common On/Off pump control box is the probe / sensor free in the well. Our special design makes it a very reliable and sensitive Protection against pump dry run without installation probe / sensor in the well.
Model L932 is useful in all cases we need to control and protect single pump managing its turn-on and turn off by different electric installations.
