description: The study is focused on the research of influence of smooth coatings applied on the flow part surfaces of mainline oil pumps on energy efficiency indicators of the mentioned pumps. The coatings used are Loctite 7227 and Belzona 1341 which allow a significant reduction in roughness of the coated surfaces. The peculiarities of the said coatings are low cost and easy application (by using a brush or by spraying) which, despite of absence of hydrophobic properties, makes them applicable under operating conditions at oil pumping stations. Experimental studies have been carried out including the coatings testing on full scale pumps MOL 1250-60 and MOL 10000-210. The results of experimental studies have been compared with the results of calculations. The results of the study have confirmed applicability of smooth non-hydrophobic coatings when applied on the flow part surfaces of mainline oil pumpsâ volutes. In addition the reliability of the proposed analytical method for evaluating the effectiveness of coatings was confirmed.
