ABSTRACT:
A high-volume, heavy-duty, magnetically-coupled centrifugal pump having flow-dividing duct configurations directing the influx to opposite sides of the impeller as the result of assembly of mating body sections defining a multi-chambered pump body and including major partitioning web and cavity configurations with cooperative plate means affording certain inflow-chamber, shaft-support, and turbulence-suppressing chamber configurations operative to diminish turbulence volume and also block transfer of turbulence effects from the magnet rotor back to the impeller while permitting liquid to fill into the magnet chamber, the magnet rotor having web and passage configurations operative to force liquid and create pressure behind the rotor to create counterforces opposing certain thrust forces.
