Features: The IEIK diaphragm pump is equipped with a power of 60W, a pressure of 116Psi, and a water flow rate of 5L/PM and 1.35GPM. If you are concerned about low water pressure or flow rate, I think this is a good choice because the strong pressure leads to loud noise. Worried about excessive noise, please choose a low-power model.
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.

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 5A-8A power supply. IEIK fresh water pressure diaphragm pump can be used for automatic pump, ocean, ship, camper, RV, agricultural spray (weak acid and weak alkali) and truck.
Note: Please test according to the requirements and use a suitable power source before use.
