1. With a pressure switch it will be automatically cut off when the pressure of water outlet is big enough. And runs again when the pressure is going down 2. The mounting feet are rubber instead of rigid plastic, which provides fairly good vibration isolation 3. Built-in pressure switch, it automatically turns on and off as you turn your tap or nozzle on and off 4. Water inlet and outlet interface connect with silicone PE or PU pipe 5. This type of product can be applied to occasions, which have demand for energy conservation and frequent switching, such as machine washing, feeding water to a solar energy system, and remote automatic controlling system of conveying water and suspending water supply, etc. Spec: Description: This high quality DC micro diaphragm pump with a pressure switch will be automatically cut off when the pressure of water outlet is big enough. And runs again when the pressure is going down. It is not a good idea let this pump runs dry for too long.
