When specifying the proper pump for any fluid application understanding the properties of the fluid to be handled is of the upmost importance.
Viscosity…. is one of, if not the most important variable when determining the proper specification of a diaphragm pump (or any pump) and associated flow rates. The viscosity of many materials fluctuate as ambient temperature’s change through the seasons and as plant conditions change month to month, so understanding the effect viscosity has on sizing pumps is important.
All AODD pump ratings are with water at the pump outlet. For example, a Graco 1050 pump is a 1″ ported pump rated at 50 gallons per minute (water at the pump outlet). When looking to specify the above example pump, three things must be further evaluated to insure proper performance/specification – Viscosity (will alter flow rate), available air pressure at the pump, pipe or hose size (at pump outlet all the way to the point of discharge). Once you have determined these variables you can properly select the perfect pump for your unique application.
Getting the right pump will make a world of difference in the efficiency of your set-up. Not only will your flow rates remain stable throughout the year, but downtime will be reduced and the life of your pump will be extended.
