A new frame design extends the life of this pump

| By Mary Page Bailey and Gerald Ondrey

The new GD 2500Q Heavy Duty Frame (HDF) quintuplex pump (photo) is designed to extend pump service life through an optimized power-end frame design. The frame upgrade has been developed to increase component thickness and allow for larger, stronger welds to boost structural integrity. The updates include: top and bottom skin plates increased in thickness, offering more structural support for nose-plate loads; main bearing plates with increased thickness that protrude between skin plates with larger, stronger welds, reducing overall frame and weld stress; stronger nose-plate support structure to reduce deflection around welds; and significant size increases in nose-plate welds, which reduces stress in critical joints by more than 20%. — Gardner Denver High Pressure Solutions (HPS), Houston
