The centrifugal pumps, used for the intra-trade oil transportation are works on the gas saturated oil-water emulsions. The construction of pumps influences physical-chemistry and rheological properties of the transported emulsion, in flow area structural changes occur, dispersiveness and viscosity rise. The properties of emulsion, in turn influence pump specification, is reduced efficiency, increase the required power. New method of the analysis of pump specifications is proposed, solutions by increase of effectiveness in the work of pumps on emulsion given.
