Abstract
A submersible pump having a plastic housing and adapted to accommodate multiple pump stages. The housing includes a pair of housing halves which enclose the impeller cartridges of the pump and an adjustment cone to retain the impeller cartridges for proper operation. Different length housings to accommodate a varying number of impeller stages are manufactured from the same mold utilizing removable inserts to vary the length of the mold. Accordingly, substantially integral housing halves can be formed at a substantial reduction in cost.
