    Applications

    Applications of Air Operated Double Diaphragm Pump

    Tips: Air powered double diaphragm pump troubleshooting

    The pneumatic diaphragm pump cannot start or moves slowly.

    • Check whether the filter, pressure regulating and lubricating device and the air inlet filter are blocked.
    • Check the spindle and "O" ring for scratches, abrasions and flattening marks, and replace them if they are damaged.

    The pump is running but the flow is too low

    • Check the pump body for cavitation spots and adjust the inlet pressure of the compressed air. Reduce the running speed of the pump body to adjust the viscosity and concentration of the liquid.
    • Check whether the valve ball is stuck. If the conveyed liquid does not match the material of the valve ball. The valve ball will expand. Please replace the ball and seat with a suitable material.
    • Please check whether the inlet pipe is blocked.

    There are a lot of bubbles in the outlet liquid

    • Please check whether the diaphragm is broken.
    • Check if the pump body and pipeline are leaking.

    Liquid leaks from the outlet of the gas chamber

    • Please check whether the diaphragm is broken.
    • Check whether the diaphragm is correctly installed and locked.

    Import and export leakage.

    • The screw is not tightened
    • the ball seat is deformed or the O-ring is damaged
    • The pump casings at both ends are not inclined to the upper hole position, causing the two discharge ports or feed ports to not be on the same plane.

    Very pleased with this AODD pump.
    For the price this is a hell of a deal. I like the packaging and let me receive a perfect product. I’ve used this air operated diaphragm pump pretty heavily the last month and a half. No issues so far. I am very pleased with this pneumatic pump.

    I recommend it.
    This air operated double diaphragm pump is heavy duty but relatively lightweight construction, which makes this an excellent choice for any application. Well made and quiet during operation. I recommend it.

    Fast shipping and worked great.
    I ordered this air operated diaphragm pump because a friend of mine has one and he raves about how great it is. I used it to pump the oil from the barrel into a waste oil heater. This AODD pump delivered on time and worked great. I highly recommend.

    I would recommend this AODD pump.
    I use this air diaphragm pump to move waste engine oil into a storage container. I have only had it for a short time, doesn't seem to move 12 gallons per minute but still meets my needs. I would recommend this AODD pump so far.
