Product Description
Intelligent Pump Controller model M931 is an easy to use, programmable controlling & protection device for direct start, three phase deep well submersible pump, centrifugal pump, pipeline pump etc with output power from 0.75KW to 7.5KW (1HP-10HP)
Model M931 has many operation modes by adopting different electric installations. An important feature that makes the difference between Model M931 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.
