The results of investigation of the effect of additional charging of dielectric liquid after interelectrode gap on static output characteristics of the two-stage pump are presented. It is shown that the increase of in- homogeneity of an electric field on the surface of collector facing the second stage by applying of the perforated insulating coating to its particular part results in the increase of head by 70–80%. This allows us to significantly improve performance and reduce the size of a multistage electrohydrodynamic pump.
