Diaphragm pumps are increasingly being used due to their high reliability compared to alternative pump types because they contain few moving parts, no parts in sliding contact and no shafts or bearings requiring sealing from the media.
How do I choose a diaphragm pump?
The important thing to know for your particular diaphragm pump is that you have the proper amount of air for your pump to operate and that the pump will be able to deliver material at the rate you want and over the distance you need to deliver material.Nov 21, 2017
Why do diaphragm pumps fail?
Running the pump dry is a common way that diaphragms will fail. It sounds pretty obvious, but very common. Another way diaphragms rupture is by operating the pump higher than maximum pressure ratings. Sometimes operators crank up the compressed air pressure to get the pump's reciprocating action to work faster.
