Although Goulds X-Series Power Ends are designed for tough conditions, some applications push a power end beyond ANSI design limits. Three examples are:
  1. a pump is operated at reduced flows,
  2. pumping high specific-gravity liquids,
  3. overhung belt drive applications
These cause excessive loads which result in increased shaft deflection. This leads to premature bearing and seal failure.

Goulds ANSI PLUS TM LTX Power End is a practical solution. An oversized shaft and bearing assembly significantly expands the limits for long, trouble-free bearing and seal life.
