Abstract (en)
The present application provides a submersible pump. The submersible pump includes a pump body (1) provided thereon with a control panel (2); a controller (11) electrically connected to at least two sensing assemblies (3); and the sensing assemblies (3), each including a liquid level sensor (32), an indicator light (33), and a switch (31); where, the switch (31) is provided on the control panel (2) and is configured to turn on or off the liquid level sensor (32); the indicator light (33) is configured to display an on/off state of the liquid level sensor (32); and all the liquid level sensors (32) are arranged at different heights on a side of the pump body (1). The submersible pump can simultaneously turn on at most two liquid level sensors through the switches and detect different liquid levels by turning on the liquid level sensors at different heights.
