It features a magnetic control unit that automatically detects water flow, ensuring your laser tube remains protected from overheating. With a flow rate of 3000L/h, it is compatible with various laser tube wattages, making it a versatile addition to your setup. ## Description Features: The flow switch of the pipe booster pump performs the on/off control of the sensor elements via a magnetic control unit with water flow and thus achieves the effect of starting and shutting down water pumps. This water switch is used to protect the laser tube. If the water pump does not work, the water sensor can detect and shut down the laser system. The laser tube is therefore not damaged. It can be used with a water pump instead of a radiator Stroke 3.2m, flow rate: 3000L/h, for 40W/60W/80W laser tubes Specifications: Socket part: G1/2. Connector: G1/2.
