Product Details
✓Features: The IEIK diaphragm pump is equipped with a power of 45W, a pressure of 108Psi, and a water flow rate of 4L/PM 1.05GPM. It belongs to medium water flow and pressure, with much lower noise, and can meet normal boosting needs.
✓Function: When the IEIK pressure diaphragm pump is powered on, opening the valve will start working, and closing the valve will automatically stop working. The IEIK pressure diaphragm pump is equipped with a protective device, which can effectively prevent the diaphragm pump from melting or burning when overloaded or blocked. IEIK water pressure pumps can not only help you solve water pressure problems, but also ensure safety during operation.
✓Parameters: Vertical suction stroke of water pressure diaphragm pump 3.3ft, inlet pressure 0.2Mpa, rated pressure 0.75Mpa, flow rate (maximum) 4L/min, size 16.5 cx 9.5 cmx 5.5cm, water pipe interface 1/2-inch thread. The pressure regulation function of the water pressure pump is not explicitly stated in use. In order to achieve the best working condition of the water pump and improve the user experience, we have cancelled the pressure regulation function in the design.
✓Application: Before formal use, please connect the water inlet to the pressurized water supply pipe, and after a few minutes of power on trial operation, move it to the working environment. Please use DC12V 4A-6A power supply. IEIK fresh water pressure diaphragm pump can be used for automatic pump, ocean, ship, camper, RV, agricultural spray (weak acid and weak base) and truck.
✓Note: Please test according to the requirements and use a suitable power source before use. IEI diaphragm pump is not a submersible pump, please pay attention to waterproofing and prevent short circuits. Diaphragm pumps are tested before leaving the factory, and there may be some water inside the pump. If you encounter any problems during use, please feel free to contact us, and we will answer relevant technical questions as soon as possible.
✓Tip: When the water pump vibrates and makes a dry noise but does not work after being powered on, please use an air compressor to blow gas from the water pump inlet to discharge the gas from the outlet, and it can work normally.
