Gardner Denver High Pressure Solutions (HPS) recently launched the GD 2500Q Heavy Duty Frame (HDF) quintuplex pump, designed to extend pump service life through an optimised power end frame design.
The frame upgrade will increase component thickness and allow for larger, stronger welds to boost structural integrity. The upgrade was designed to reduce stress in vulnerable areas of power end frames.
The updates include top and bottom skin plates which have increased thickness for more structural support for nose plate loads. The main bearing plates also have increased in thickness and protrude between skin plates with larger, stronger welds, reducing overall frame and weld stress.
There is stronger support structure for the nose plate to reduce deflection around nose plate welds, and an increase in the nose plate weld size, reducing stress in the critical nose plate joint by more than 20%. Deep bevelling around the outer main bearing plates gives a much deeper weld throat. The snap ring bearing retainer has been replaced with a stronger, bolt-on outer main bearing retainer, giving improved axial tolerances for improved gear timing.
