When to use Double Diaphragm pumps Double Diaphragm pumps are designed for volume transfer applications and are usually unsuitable for very viscous products or where there are long pipe runs and high discharge heads to overcome. FES can supply special pumps for working under these more difficult conditions. If you are unsure which is the best pump for your application, call the experts at FES. Air valves Graco have developed very reliable air valves with the number of working parts reduced to a minimum. Spares Spares for wetted parts are available in a variety of kits for convenience when replacing wearing parts in pumps.
