GEAR PUMP WITH MAGNETIC DRIVE Russian patent published in 2008 - IPC F04C2/10 

FIELD: mechanical engineering; pumps.

SUBSTANCE: invention relates to positive displacement gear pumps, particularly, to gear pump with magnetic drive. Proposed gear pump with magnetic coupling has pump housing with at least one inlet hole and at least one outlet hole, rotating ring unit of magnetic drive arranged in pump housing and provided with recess at one end, ring tank with recess at one end, at least part of tank being arranged in recess of rotating ring unit of magnetic drive and installed for sealing engagement with pump housing, ring driven unit consisting of magnet and rotary gear wheel with magnetic part placed in recess of ring tank and magnetic part mainly aligned with unit of ring magnetic drive, displaced stationary shaft with first and second parts of shaft with longitudinal axis of first part of shaft parallel to longitudinal axis of second part of shaft located at a distance from the latter. In process of rotation of ring unit of magnetic drive, ring driven unit consisting of magnetic and rotary gear wheel rotates on first part of displaced stationary shaft, and rotary gear wheel sets into rotation idle gear wheel which rotates on second part of displaced stationary shaft.

EFFECT: simplified design.
