    What are the benefits of using an Air Operated Diaphragm Pump?

    Tapflo Diaphragm Pump Range

    Tapflo’s Air Operated Diaphragm Pump range

    Air Operated Double Diaphragm Pumps (AODD) have a huge list of benefits over electric centrifugal style pumps.


    The first and most relevant benefit of using a Diaphragm Pump would be the versatility of the pump. Air Operated Diaphragm Pumps have no BEP (Best Efficiency Point) and do not experience any adverse effects when operated at different flows and pressures. In short, one pump can do a lot of flows and pressures without damaging the pump.

    There are also a wide range of installation possibilities for Diaphragm Pumps. Tapflo’s AOD Pumps can be submerged in the fluid, they can be installed above the medium as they can create a high vacuum suction or they can be installed with flooded suction. Our team can meet a range of installation and application requirements.

    Operate for extended periods of time

    “AODD pumps can be abused.” This is a statement you may hear often in a busy factory and it does carry some truth; you can run Air-Operated Diaphragm Pumps dry for extended periods of time, they can be dropped, switched on and off and they do have solid handling capabilities, which makes AODD’s the perfect choice for many factories. However, just because you can abuse them doesn’t mean you shouldn’t take care of them! Running an Air Operated Diaphragm Pump dry for extended periods of time will cause more wear to the parts meaning they will need replacing more often.


    Another great benefit of using a Diaphragm Pump is that they are all self-priming, most of them up to 9 meters wet! Self-priming means the pump will actually lift media up out of a holding tank, through the pump and onward.


    Tapflo’s Air Operated Diaphragm Pumps have been designed to support quick and easy maintenance. We also have a range of pneumatic accessories designed and manufactured in the UK to support the Diaphragm Pump’s operation and easily integrate routine maintenance into the process. Diaphragm Pumps are low maintenance and as a result are an option for low cost ownership.

    Long Life Design & Parts

    In every Tapflo Diaphragm Pump, we use no-nut, clean face diaphragms. This ensures that the diaphragms are primed for heavy duty operation and increases their life span. Rather than using a nut to hold the components of a diaphragm together, they are chemically bonded.

    Tapflo’s Diaphragm Pump housings have been designed to ensure minimum parts for easy maintenance and durability. Our HDPE/PTFE range are manufactured from solid block material and our metal side housings are made from cast Aluminium, Iron or Stainless Steel. This ensures that Tapflo’s side housings are robust, removing potential weak spots that would be prone to leakage which you may notice in standard Diaphragm Pumps on the market.

    Are there any limitations to using an Air Operated Diaphragm Pump?

    As good as the pumps are, they do have some operational downsides, listed below:

    • Compressed air is one of the most expensive ways to power a pump, meaning that air pumps cost a hefty amount of money to run.

    If this is one of your biggest worries about purchasing a Diaphragm Pump, you should take a look at our article, ‘Are Your Diaphragm Pumps Costing You Too Much?’ Tapflo UK has got the answer to help reduce your reservations surrounding Diaphragm Pumps. With LEAP technology, Tapflo UK can save you up to 70% on your energy costs!

    • Air Operated Diaphragm Pumps are also noisy when running at high pressures.
    • The output from AOD Pumps is quite uneven and can only be fixed with a Pulsation Dampener, and/or LEAP Pumps.
