Effects of viscosity and suction lifts on flow rates

This is a very important factor when considering the use of a Double Diaphragm pump. Please see Al overleaf.

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 for wetted parts are available in a variety of kits for convenience when replacing wearing parts in pumps.
