FIELD: engines and pumps.
SUBSTANCE: invention relates to pumps intended for use in inflammable zones of oil processing plants. Proposed pump comprises outer housing 1 with intake and discharge branch pipes 2, 3. Feed cover 4 and discharge cover 5 with brackets 6, 7 for bearing 8, 9 and seals 10, 11 are arranged on sides of housing 1. The latter accommodates guide vanes 12, 13, 14, sections 15, 16, adapter 17 and rods 18, making inner housing. Aforesaid components accommodate rotor consisting of shaft 19 with axial force relieve device 20, impellers 21, 22, 23 and front wheel 24. assembly units and parts are connected to outer housing 1 via its circular step 25 representing web 27 with gasket 26. Modular unit is pressed against outer housing 1 by flange 28. Note that geometrical sizes of outer housing 1 do not vary. Note also that step 25 is arranged to devide distance between axes of branch pipes 2, 3 into equal parts with the help of circular web 27.
EFFECT: possibility to use modular components.
