This article describes development of pipeless device for water lifting through well casing string. Intensive development of all sectors of national economy requires for increased water consumption. Water supplies from open sources in Kazakhstan are nearly exhausted, thus, now-a-days underground waters are intensively extracted. The developed pipeless device for water lifting provides fixation of submersible pumpsat preset depth in well; possibility of repositioning to higher depth; discharge of water column above the device during mounting works, which excludes swabbing; protection of sealing element against contact with casing string during tripping and possibility to flush sand deposits from packer due to its shape in transit and working positions, resistance against sand-off; maintainability of sealing element under field conditions; adjustment of maximum permissible working pressure on sealing element; manufacturability and unification of structural members of various form factors. Accompanying engineering equipment makes it possible to seal mouth well, to provide fixation and sealed inlet of electric pump cable into well, protection of the cable against deformation during mounting operations, to perform mounting and dismounting with serial machinery (mobile cranes, drilling rigs
