148 Centrifugal Pumps: Design and Application Figure 10-10. Volute inserts. Bi-rotors Unusual pipeline requirements can often be satisfied using bi-rotor pumps. These are basically two single-stage pumps on the same shaft, with two conventional incoming and outgoing nozzles at each body cavity. Originally developed with double-suction impellers to reduce NPSHR at high flow rates, this design is extremely flexible. Two applications are now described. Bi-rotor pipeline pump. The pipeline conditions illustrated in Figure 10-15 have an ultimate pipeline capacity of 60,000 GPM requiring three pumps operating in parallel with each pump delivering 20,OCX) GPM at maximum pipeline pressure. During the early life of the pipeline, initial throughput would be 40,000 GPM. This would normally mean operating two pumps in parallel and throttling out excess pump pressure or reducing pump speed. A more economic approach would be to install a birotor pump with case construction that permits operation of the impellers either in series or in parallel. The conventional, integral cast cross-over
