Vertical Pumps

 

Vertical pump is a long, slender multistage pump designed primarily to pump water from deep wells.


Advantages for vertical pump

  • Less floor space required
  • Inline piping arrangement allows piping in any direction in most cases.
  • Elevated motor protects against potential flooding if the pump station is in a low area

Concerning rotor-bearing mechanics, vertical pumps are fundamentally more difficult to analyse and understand than horizontal pumps primarily because the radial bearing loads are not dead-weight biased, the rotor weight being carried by axial thrust bearing. Radial bearing static loads in vertical pumps are therefore significantly less well defined and more non-stationary than bearing static loads in horizontal pumps. Given the strong dependence of journal bearing rotor dynamic characteristics on bearing static load, the rotor vibration characteristics of vertical pumps are typically quite uncertain and randomly variable, far more than those of horizontal machines.
