Abstract
A segmental ring centrifugal pump wherein the channel ring and the diffuser/crossover hydraulics are formed as a single monolithic casting. By casting the diffuser and the channel ring as a unit, the monolithic diffuser channel ring member and the diffuser vanes provide structural support to the channel ring. The channel ring wall thickness has been reduced by taking advantage of the reinforcing function of the monolithic cast piece. The reinforcement of the channel ring wall and the minimum wall thickness can be adjusted by modifying the radius between the diffuser vanes and the channel ring.
