The Plug&GO pump completely protects itself against lack of water in the well or tank, without the aid of other equipment (probes, cables, sensors, control panels, etc..). In case of dry-running, the Plug&GO pump automatically stops, to restart after a programmed cycle time.
The Plug&GO pump is automatically protected against motor overheating. This can happen because of: the high temperature of the pumped liquid; when the minimum distance between the pump installed and the well bottom isn’ t respected; when the pump is installed in well/tanks bigger than 4” without a proper cooling system; when the pump works in shut-off. In such cases, the thermal protection system stops the pump, which automatically restarts as soon as the correct working temperature parameters are restored.
The Plug&GO pump is completely protected against overload. In case the pump is partially or totally blocked, the Plug&GO® software, after some automatic restart attempts, automatically makes the pump enter the stand-by mode.
The Plug&GO pump is protected against low or high voltage, that can damage the motor. Low voltage can occur, for example, if the section of the power cable is not adequate considering the motor power and the distance between the plug and the pump itself; or if a generator is faulty or undersized for the pump. High voltage can occur with unstable supply network or with a faulty generator. In these situations, in order to avoid potential damages, the Plug&GO® pump stops running. A number of consecutive automatic attempts verifies if the operating parameters are correct; if they are not, the pump enters the stand-by mode.
The Plug&GO pump is automatically protected against leaks in the piping system (also when the pressure tank is exhausted or its membrane is damaged) and too frequent starts and stops (for example if the tank is of the incorrect size). In these cases, the Plug&GO® automatically enters the stand-by mode. It is always necessary to install a pressure tank on the delivery pipe, between the pump and any other devices (such as reducing valves, filters, etc.).
An electronic “soft start” reduces power consumption at the start of the pump. It will avoid annoying drops in power i.e.: flickering lights. Thanks to this function, energy will be saved and the pump will be more reliable. This will also extend the pump’ s life. The Plug&GO pump starts and works even in case of tension drop.
SLP device protects the electronic inside the Plug&GO pump against voltage peaks, which can be caused by electric abnormalities in the supply network or by other various electrical interferences. It reduces overvoltage, keeping the correct operating voltage range or interrupts the power supply in case of very high peaks. It is recommended to install Plug&GO pump with SLP protection device.
The Plug&GO pump regularly controls if the check valve works properly and if it is not clogged by any impurities. In case it is clogged, a special electronic procedure mechanically releases the check valve or makes the pump enter the stand-by mode.
