In December, I shared with you 3 Air Operated Diaphragm Pump (AODD) installation traps. There are another 3 common installation traps that I see maintenance teams make when installing them.
I thought I’d share these with you here to save you the time and hassle of having to wait until something stops working on your AODD pumps to go and troubleshoot it and fix it.
A lot of plants choose to use AODD pumps when self-priming is required. If you just switch the air flow from off to the required flow rate, you may find that there is not enough time for the fluid to be drawn into the pump to prime it…
This can be avoided by just turning down the compressed air at the regulator for a few seconds – letting the pump work at the reduced pressure – which allows it to draw the fluid into the pump and prime it.
Then you can turn the pump back to full operating speed.
