All Electric Double Diaphragm Pump - A Game Changer

Updated: Jan 10

The all electric diaphragm pump is a game changer in the world of double diaphragm pumping. It is a positive displacement pump for municipal sludge, slurries, pastes, or anything that an air operated diaphragm pump can pump, but without the usual drawbacks of air.

With customers looking for alternatives to air operated diaphragm pumps due to cost, efficiency, functionality, safety, and energy usage, the unique design and impressively low energy consumption of the ABEL EODD (electrically operated double diaphragm) pump, has once again solidified ABEL's reputation as the world leader in diaphragm pump design. Available in four different material designs including nodular ductile iron, stainless steel, aluminium, or polypropylene, and with an efficient motor and pump design, ABEL's EODD offers the lowest in class operating costs - and superior durability. In most cases, this can mean up to 95 percent volumetric efficiency on average compared to any other pump. You no longer need to use electricity to run air to run a pump, with only mechanical fluid dynamics to deal with instead of fluid and air.

Simple Solution, Many Benefits

  • High efficiency, electro-mechanical drive and slow stroke rates, keep energy bills low and wearing parts cost to a minimum.

  • Mechanical simplicity makes maintenance a breeze, unlike progressive cavity pumps, gear, rotary lobe, or peristaltic type pumps.

  • A design that offers a robust construction with integral metal core ball check valves and fabric-reinforced diaphragms that offer a smooth mechanically controlled linear drive, would prove the most desirable.

  • Large ports, a diaphragm that is to one side of the fluid column offers passive pumping as well that allows for better fluid velocity and more room for the fluid, and therefore is less prone to plugging. Other pumps require tight tolerances simply to operate, making them susceptible to plugging by nature.

  • If the media is compressible and will flow freely, it can usually be pumped with an EODD pump, up to a range of approximately 40 percent solids. Large valve clearances also contribute to this winning equation.

  • True process control is achieved via optional variable frequency drive, technology unavailable in air operated diaphragm pumps.

  • There is no air valve to stick or malfunction in cold and hot weather.

  • Optional discharge dampeners and suction stabilisers are available to minimise flow pulsations under variable or demanding system conditions.

EODD pump also offers the extreme versatility of operating in duplex mode with two pumps working at the same time – something that an air operated double diaphragm pump cannot do. Since an EODD pump operates by working on a 90 degree out-of-phase design, you can use two pumps in tandem at the same time and not only the traditional lead/lag fashion. This means that you only use one motor, one gearbox, one base plate, and one manifold piping system – further saving on material, time, money, and even weight as compared to two independent pump systems.


A truly all electric double diaphragm pump with a superior design will provide the very best return on investment that checks all of the boxes when it comes to pump selection and lasts two to three times longer with better parts wear and less maintenance than air operated double diaphragms.
