The Gardner Denver GQ-GXN(A-D) is a mud pump series whose power end is built on a monolithic alloy or ductile iron frame. Its crankshaft is forged from quality alloy steel, and the series uses a continuous herringbone gear design whose opposed helix angles cancel axial thrust during meshing for smooth power transmission. Factory spec data lists a max working pressure of 4515 PSI and a rated speed of 70 SPM, with liner bores of 5 in, 6 in, 7 in and 8 in appearing across configurations and per-liner maximum working pressures rising to 4515 PSI; configuration-specific ratings available on request. We supply fluid-end replacement parts for this series to operators in Canada, the United States and international oil and gas markets; contact us for current availability.
