Abstract:
A system (10) for transporting and dispensing fluent materials consists of a shipping container (20) disposed with a supply of fluent material, and having a bottom wall (202) with an outlet aperture, the outlet aperture being occluded by a normally disabled transfer valve (25); a base container (30) adapted for sealed attachment to the bottom wall (202) of the shipping container (20), the base container (30) having a top wall equipped with a means for enabling (35) the normally disabled transfer valve (25), when the base container (30) is properly attached to the shipping container (20), and a bottom wall which tapers downwardly to an opening with a valve (40) for dispensing particulate material at a controlled rate when the valve (40) is opened. A remotely operable metering valve is also disclosed as a substitute for the valve (40) in the base container opening.
Abstract:
An integral pump motor (97) or sealless magnetically coupled pump having a shrouded impeller (10) with a removable magnet carrier ring (30) attached to one side of the impeller shroud. Permanent magnets (38) are embedded in the magnet carrier ring and encapsulated to prevent contact with potentially agressive pumped fluids. The magnet carrier ring is mounted to the impeller shroud using an interlocking (or multiple keys) (32, 34) to transmit torque. The magnet carrier ring is fastened axially to prevent separation from the impeller shroud. Damage or breaking of the blading of the impeller and its being rendered inoperable will not necessarily dictate the accompanied loss of the high value magnet ring.
