material: The automatic water pump uses PP material with good oxidation resistance, temperature tolerance, insulation, and durability. It is designed for reliable longterm use in demanding environments. Control and protection: The pump float switch can automatically regulate water level to prevent overflow, and it can be installed on a submersible pump to control and protect the motor from running dry or overloading. Product information: Cable length 5 m; float switch size 10.3 x 7.8 x 4.5 cm (L x W x H); waterproof rating IP65; power consumption less than 500 W; working voltage 220/380 V; max heater current 10 A at 250 V (max). Construction principle: The water level controller operates on gravity and buoyancy principles to manage water level inside and outside a tank. It features a simple, safe, and reliable design that is nontoxic and environmentally friendly. Practical applications: Domestic rainwater or water storage tanks: automatically stop the pump at the desired level to prevent overflow. Small farms, greenhouses, or aquaculture setups: pair with a submersible pump to maintain stable water levels and protect the motor. Basements, workshops, or sump applications: use to regulate drainage with a pump, reducing overflow risk and extending equipment life.
