Engineered with separate induction and magnetic chambers to avoid iron interference, it supports water temperatures up to 70℃, making it ideal for both hot and cold water systems. Lightweight and compact, it’s perfect for enhancing water heater ignition and solar water circulation in low-pressure environments. ## Description Turn on the water equipment and water will flow in pipeline. Water impulse induction door to rotates towards the direction of water, and magnetic control device rotates together, which will trigger the sensing elements when it reaches a certain position, to switch on the household pipeline boost pump. When water flow is turned off, induction door drives magnetic control device to a certain position under the action of the reset spring, to switch off pump. Features: induction chamber, magnetic control chamber and electronic components are designed separately in order to avoid switch failure caused by iron matter in pipeline is magnetic adsorbed. High temperature materials allows the product to be used for both hot(up to 70℃) and cold water. Low water pressure startup; reset spring is made of stainless steel; it can start up pump when water pressure is >0.03KG. The electronic components as control device will not cause spark during work which is quite safe. This product is widely used for low pressure area family, especially important for low water pressure ignition start-up of water heater, automatic water cycle of solar water heater.
