    Tips: The functions of electric diaphragm pump components

    • Air valve: The plastic or metal valve shell is fixed on the pump center body by four screws.
    • Piston: The aluminum cylinder is enclosed in an air valve to control the air flow.
    • Cavitation: Due to the reduced or lack of fluid supply at the pump inlet, the pump discharge is lower than the rated volume. In fact, the liquid chamber is not filled with fluid before discharge.
    • Static discharge head: the vertical distance (in meters) from the center line of the pump to the free delivery point.
    • Inlet pressure: The inlet is measured in Bar, including the specific gravity and flow rate of the fluid.
    • Specific gravity: the ratio of fluid weight to water weight at 4 degrees. The specific gravity of 4° water is 1:0, and the static suction lift is the vertical distance from the liquid level to the center line of the pump. The pump should be above the liquid level.
    • Vapor pressure: The pressure of vapor generated by all liquids on its free surface. In any pump operating system, the operating pressure cannot be lower than the vapor pressure, and the formed vapor will be partially or completely cut off into the pump fluid.
    • Viscosity: Due to the internal friction of the fluid, the nature of viscosity makes the fluid flow resistance.
    • Water hammer: The higher inlet forms a static pressure head which acts on the pump to generate internal pressure.

    I like it!
    I really like ATO electric diaphragm pump with 4 inch fluid inlet and outlet size. It is a more powerful pump with more flow and pressure than my old one. It is quiet. Easy installation. I have been using it for a few days, so far so good. I will recommend it to my friends.
