Two injection type electrohydodynamic pumps with blade-blade with insulation coating type electrodes and grid-grid type electrodes made of bare wires and wires covered with perforated insulation have been studied. There was a movable flow-limiting partition in the interelectrode space of the second pump. The current-voltage and pressure-flow rate characteristics of the pumps are given when using pure transformer oil, transformer oil-butanol mixtures ans polyethylsiloxane liquid. The optimal interelectrode gap distance, conductivity of the medium and position of the flow-limiting partition has been established, which ensures maximum pressure (in transformer oil, the pressure was 1.8 times higher than in polyethylsiloxane liquid).endielectric fluidelectrohydrodynamic pumppartitionperforated insulationpressureArticlehttps://doi.org/10.59295/spd2024n.111
