Key Features Premium Material: It is mainly made of high-class material, which is impact-resistant, wear-resistant, and scratch-resistant, with high durability and reliability, ensuring long-term use. Excellent Performance: Compared to the traditional mechanical switch can only be installed near the pump, it allows you to freely install it in the constant pressure pipeline, even in the high-rise water supply can also support good results. Powerful Function: It allows you to freely adjust pressure start and stop, ensuring the stability of the outlet pressure and preventing the water pump from frequently starting. Thoughtful Design: It combines a pressure switch and pressure gauge, allowing you to control the water pump while observing the data of the pressure gauge to judge the performance and faults of the pump for timely maintenance. It takes a photoelectric quiet design with low running noise, which will not disturb your work life. Large Testing Range: It has two pressure units, making it very convenient. The inner circle in red is the psi value with a test range of 0-150, and the outer in black is the bar value with a test range of 0-10. Application It is suitable for submersible pumps, self-priming pumps, jet pumps, deep well pumps, and so on.
