The insert has a second portion extending radially outwardly and including a mating projection for engagement with the outer shell projection to form an inner circumferencial volute wall portion. A backplate has a third projection adjacent its outer circumference that is received in a relief in the outer shell and completes the outer circumferncial volute wall portion. The outer shell projection has a first land engaging a second land on the mating projection, the first and second lands spirally descending relative to a datum and the relief has a third land in spaced relation to a fourth land on the third projection, the third and fourth lands spirally descending respectively relative to the datum. |
