    Electric operated double diaphragm pump, short for EODD pump, is driven by an electric gear motor, and the double diaphragm is driven to reciprocate and weakly through the crankshaft slider mechanism, so that the volume of the working chamber is alternately changed to achieve continuous suction and discharge of liquid. The electric powered diaphragm pump is widely used in petrochemical, ceramics, metallurgy and other industries. ATO.com offers fluid outlet and inlet 3/8", 1/2", 1", 1-1/2", 2", 3", 4" electric diaphragm pump for your choice, body material of plastic, aluminum alloy, stainless steel and cast iron available, high performance and high efficiency for delivering high viscosity fluids, slurry, acid and alkaline liquids, toxic liquids and so on.

    How does an Electric Diaphragm Pump Work?

    The electric diaphragm pump is a new type of pump, because of the breakthrough in the diaphragm material, to be used in petrochemical, ceramics, metallurgy and other industries, is characterized by no need for irrigation water, strong self-priming ability. The motor drives the reciprocating motion of the diaphragm on the plunger at both ends through the reduction box. In about two pump chambers, equipped with up and down four one-way ball valve diaphragm movement, resulting in the volume of the working chamber change, forcing the four one-way ball valve alternately open and close, so that the liquid is constantly inhaled and discharged.

    ATO Electric Diaphragm Pump Features

    • No need to irrigate and divert water, and the self-priming capacity is more than 7 meters.
    • With good passing performance, particles and mud with a diameter of less than 10 mm can pass through effortlessly.
    • Since the diaphragm separates the conveyed medium from the transmission mechanical parts, the medium will never leak outward. And the pump itself has no shaft seal, and the service life is greatly extended. According to different media, the diaphragm is divided into neoprene, fluororubber, nitrile rubber, etc., which can fully meet the requirements of different users.
    • Small size and light weight. Due to the planetary cycloid transmission structure, the pump type is small in size. Compared with the same type of pump, its volume and weight are reduced by about half.

    Electric Diaphragm Pump Troubleshooting

    Faults Reasons Solutions

    What is the Flow Characteristic of Electric Diaphragm Pump?

    The flow characteristics of the electric diaphragm pump refers to the relationship between the relative flow of the medium through the valve and the displacement (the relative opening of the valve), the ideal flow characteristics are mainly straight line, equal percentage (logarithm), parabola and fast open 4. There are only three ideal flow characteristics in common use: straight line, equal percentage (logarithm) and fast opening. Parabolic flow characteristics between straight line and the same percentage, generally can be used to replace the same percentage characteristics, and the fast opening characteristics are mainly used for two adjustment and program control, so the diaphragm pump characteristics is actually a straight line and the same percentage flow characteristics of the choice.
