PROGRAM EASES PUMP SELECTION
02 November 2012
AOD (air operated diaphragm) pumps are available in seven sizes to handle flow rates from a few cc/min to 52m3/hour.
Selection of this type design is important for maximum performance and minimum maintenance. Optimum pump selection is now possible with the PSI computer selection program available over the Internet.
The computer program starts with the flow rates, heads, viscosity and fluid itself. After entry, various models are displayed to meet the inserted specifications. One more click and the curves are presented for the respective offered models. This allows the comparison of various sizes to meet the application needs.
A complete pump model is outlined and displays suggested wetted parts for the AOD pump.
Once the model is selected, based on the fluid requirements, the AOD offers a low maintenance product with the fewest air valve components of any of the other AOD suppliers.
With the low parts count this means fewer parts to fail in the valve section. To complete the correct pump installation, a wide range of accessories pulsation controls, air regulators and diaphragm monitors can be supplied.
