Abstract
A sealless pump including a casing carrying an inner rotor that carries magnets mounted on a shaft connected to the pump impeller. A thin can-shaped shell is mounted over the inner rotor and an outer frame is mounted over the shell. The outer frame includes an outer rotor carrying magnets adapted to couple magnetically with the inner rotor to drive the pump through the shell. A pair of guide posts are anchored to the casing and extend through holes in the outer frame for guiding the outer frame into and from an assembled position. Bolts are threaded into the guide posts and have suitable abutments for engaging and moving the outer frame between assembled and disassembled positions.
