Preventing Emulsification - Best Pumps
Preventing Emulsification - Best Pumps
(OP)
I am working on a project requiring pumps to transfer oily water to an oil water separator. What pump type provides the least amount of emulsification? Low RPM positive displacement seems ideal, but I'd like to get some feedback from people familiar with similar applications.

Thanks for the tip on DiscFlo pumps. It was initially counterintuitive (for me) to think of the DiscFlo pump as a low shear pump, but maybe it's exactly what I need in an application I have here at work. I need a treater feed pump to do about 40 m^3/hr @ 60 m head, pumping a 3:1 emulsion with water and 21-API oil. Up until now I have been thinking of a progressive cavity pump. I'll look into DiscFlo some more.

These pumps were used as "mixers"/"circulators". They are cost competitve, engineered and can be quick turnover pieces of equipment.

The screw / centrifugal impeller with its open channel impeller design combines the gentle action of a screw pump and the high flow rates and cost efficiencies of a centrifugal pump.
