Abstract

The term “casing” is generally used to describe the component that “contains” the pump. In practice a pump’s casing has five functions:
  1. 1.

    Provide pressure containment.

     
  2. 2.

    Incorporate the collector, either as an integral part of the casing or as a separate piece.

     
  3. 3.

    Permit rotor installation and removal.

     
  4. 4.

    Support the pump or provide a structural connection to the pump’s support.

     
  5. 5.

    Maintain alignment of the pump and its rotor under the action of pressure and reasonable piping loads.
