Center-line Mount Casing

Centerline Mount CasingDesign Advantages

  • Centerline Supported Casing
  • Most ANSI pumps are designed with foot mounted casings.  The mounting foot is cast into the casing, and bolts directly to the baseplate. 

    If the pump is operating at elevated or reduced temperatures then the casing centerline will move from its position during expansion.  This can cause serious misalignment issues with the driver (which is not heating and moving at same rate as the pump).  

    Centerline support simply means that the pump casing is supported at the shaft centerline. This allows thermal expansion growth of the casing to be symmetric from the shaft centerline outwards.  Coupling alignment is maintained regardless of the temperature variations.

    All EnviroPump and Seal casings through size 4x6x13 are cast with centerline support as standard.  Larger sizes will be modified to provide this feature when required.
