The Gardner Denver GP-GXP is a heavy mud pump built on a one-piece high-strength alloy cast iron frame that delivers rigidity and damping a welded frame cannot match, avoiding weld-joint stress concentration under continuous high load. The power end centers on a large-diameter forged alloy steel crankshaft with ductile iron eccentric wheels for smooth power transfer, while herringbone gears keep transmission quiet with minimal backlash and superior load distribution. Factory spec data lists a rated input power of 700 HP, a stroke length of 16 in, a rated speed of 70 SPM, a max flow of 861 GPM and a max working pressure of 3060 PSI. Listed liner performance at rated SPM runs from 8 in at 861 GPM / max 1171 PSI down to 5 in at 308 GPM / max 3060 PSI. We supply fluid-end replacement parts for this model to Canada, the United States and international oil and gas markets; contact us for current availability.
