Applications

Applications of Air Operated Double Diaphragm Pump

Tips: How to maintain an air operated double diaphragm pump?

  • Air operated double diaphragm pump is no need for any lubricant before and during you use it. But after you disassemble the pneumatic dual diaphragm pump or when you reassemble it, it is better to fill some proper grease between pitman shaft and pitman shaft sleeve. When you install the diaphragm clamp, you also can coat a layer of grease for sealing easily.
  • If you need to install the air valve and guide valve, it is better to fill a small amount of grease for better lubrication.
  • Before you install the AODD pump, you need to clean all the inside parts, check whether all the sealing parts are well sealed.
  • Air valve cover gaskets and air valve chamber gaskets have two sides that can’t be installed reversely. The upper guide valve should be confirmed in place before tightening bolts, otherwise it will damage the thimble. Four bolts on the guide valve should be balanced and not over tight, otherwise the shell valve will be damaged.

Interested in the 1-1/2” pump
Need stainless steel with heavy duty internal parts. Will be pumping sealer with sand? Teflon and stainless steel internal parts if possible. Thank You.

ATO Responded
Our ATO-AODD-40 diaphragm pump can be customized with a stainless steel pump body, stainless steel screws and stainless steel diaphragm pressure plate.
We also need to know whether the sand you mentioned contains water or liquid? If it is pure dry sand, it can Not be pumped, but if it contains liquid, it can be pumped.
Can we run this Air operated double diaphragm pump at 10 GPM as well?
I'd like to know if we can control the flow GPM with air pressure. It says rated for 40 GPM, are we able to run it at 10 GPM as well?

Yes, you can control the flow GPM. You only need to install a valve at the inlet or outlet (any port) to adjust the water in and out or the air motor's speed.
High quality air double diaphragm pump
I recently purchased my first AODD pump for transferring lubrication oil into an overhead tank.  So far it works well and has had no issues with leaking. Highly recommend it.
