Product introduction
Intelligent Pump Controller model K531 is an easy to use,programmable controlling & protection device for direct start,three phase deep well submersible pump, centrifugal pump, pipelinepump etc with output power from 0.75KW to 30KW (1HP-40HP)
Model K531 has many operation modes by adopting different electricinstallations. An important feature that makes the differencebetween Model K531 and common On/Off pump control box is the probe/ sensor free in the well. Our special design makes it a veryreliable and sensitive protection against pump dry run withoutinstallation probe / sensor in the well.

Product application
Model K531 is useful in all cases we need to control and protectsingle pump managing its turn-on and turn off by different electricinstallations.

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
