The submersible pump is a multi-staged centrifugal pump which is designed for different wells. The nickel cast iron impeller and diffuser, the K-500 monel pump shaft allows the pump to obtain a satisfied run life at the maximum stress and load. In order to support the axial load and simplify the assembly, the stages are designed to float partly or completely. The increase in hardness of the centralizing bearing surface I adaptable to pump the well fluid with solid.
