How AODD Pumps Can Handle High Viscosity

by PSG | Mar 01, 2018

Date Posted: 03/01/18

A common question asked by users of air operated double diaphragm (AODD) pumps is, “What is the maximum viscosity of a process fluid that can be transferred by an AODD pump?” In truth, the answer has little to do with the selected pump and much to do with the piping system to which the pump is connected. Users often forget this, since most AODD applications are transfer applications with a relatively low viscosity fluid. While a complete discussion of more accurate methods for evaluating pump systems is beyond the scope of this article, pump users can employ the following techniques to estimate the factors that impact flow rates in AODD systems with high viscosity fluids.
