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 us at FES.

Spares

Spares for both the air and the wetted side of the graco pumps are available in a variety of kits for convenience when servicing and replacing wearing parts in pumps.
