Using Petrochemical Company feed pump as example, the pump application characteristics of drum balance mechanism in multistage was discussed, and malfunction problem of the feed pump was analyzed.

Based on the field requests of the multistage oil pump, a measurement and control system is designed, which can realize the multiparameter.

Covering the performance range below the MC, the new MBN ring section multistage pump is the ideal choice for medium pressure pumping applications.
