The M131 Intelligent Pump Controller is an easy-to-use control and protection device for direct connection of deep well pumps, submersible pumps and surface pumps.

M-131 is perfect for 3-phase pumps from 0.75 kW to 4 kW (from 1 HP to 5 HP)

Controller operating functions

• Automatic re-start attempt after emergency stop enforced by one of the protection functions. Different self-activation timers for different emergency conditions.
• Possibility to calibrate the controller and change its calibration to match the pump parameters.
• Manual or automatic operating mode.
• Activating and deactivating the pump depending on:

1. water levels in the tank from which water is pumped,
2. water levels in the tank to which water is pumped,
3. pressure in the tank to which water is pumped.

Controller protection functions

• Overload protection.
• Voltage drop protection.
• Voltage surge protection.
• High voltage protection.
• Short circuit protection.
• Overvoltage protection.
• Doubly dry run protection by means of:

1. liquid level probes / sensors
2. Analysis of current consumption during pump operation.
