    摘要: Various rotary pumps are disclosed that are designed to pump viscous fluids or slurries. Often, the seals of such pumps can become over heated. The disclosed pumps include slots disposed in the rotors and/or slots disposed in the openings through which the drive and driven shafts task so that some of the fluid being pumped through the pumping chamber can migrate through the proximal wall of the pump casing to the seal assemblies disposed on the other side of the proximal wall of the pump casing. Thus, the seal assemblies of the pumps are cooled without resorting to the use of a cooling jacket or other cooling mechanism.

    摘要: An improved magnetic drive pump is disclosed with improved bearing support for the proximal and distal ends of the rotor shaft. Further, an improved mechanism to couple the inner magnet assembly to the rotor shaft is also disclosed. Finally a mechanism for sealing the pump chamber from the interior of the canister that surrounds the inner magnet assembly is disclosed which permits a separate supply of coolant to be used for cooling the inner magnet assembly and the proximal end of the rotor shaft wherein such a coolant is not the fluid being pumped in the pump chamber. The pump chamber is isolated from the interior of the canister.
