Product Description

Intelligent Pump Controller model M521 is an easy to use, programmable controlling & protection device for direct start, single phase deep well submersible pump, centrifugal pump, pipeline pump etc with output power from 0.37KW to 2.2KW (0.5HP-3HP)
Model M521 has many operation modes by adopting different electric installations. An important feature that makes the difference between Model M521 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.

Product application
Model M521 is useful in all cases we need to control and protect single pump managing its turn-on and turn off by different electric installations.

Typical usage scenarios include:
Houses
Flats
Holidays houses
Farms
Water supply from wells
Irrigations of greenhouses, gardens, agriculture
Rain water reuse
Industrial plants
Waste water tank / Sewage sink
