This device is mainly applied to water accumulation in mine or sump pits. It can automatically control drainage according to liquid level without requiring power supply. It is primarily used in conjunction with pneumatic turbine submersible pumps and diaphragm pumps, enabling automatic start-stop operation of these two types of pumps, eliminating the need for manual intervention, and features simple installation and reliable performance. Moreover, as it is fully pneumatically controlled and does not consume electricity, it avoids potential hazards caused by electrical power.
