FIELD: engines and pumps.
SUBSTANCE: proposed pump relates to dynamic pump units for transfer of high-thickness aggressive inflammable fluids containing solid and soft inclusions. This pump comprises housing with tangential bend with fluid feed and exhaust pipes, shaft with discs that feature wavy surface. Note here that one or more discs with said wavy surface feature radial arrangement of waves of variable radius increasing from wavy disc centre to its periphery.
EFFECT: high head and guaranteed efficiency and laminar working fluid flow.
