The Gardner Denver FQ-FXQ is a mud pump whose power end frame is cast in one piece from high-strength alloy cast iron or nodular cast iron. Its continuous-tooth herringbone gear has opposed helix angles on the two halves, so axial thrust cancels out during meshing, and the components that turn rotation into reciprocating power are made to high material and process standards. Factory spec data lists a rated input power of 320 HP, a stroke length of 16 in, a rated speed of 65 SPM, a max flow of 748 GPM and a max working pressure of 1319 PSI. Listed liner performance at rated SPM includes 7.25 in at 748 GPM / max 553 PSI and 5 in at 325 GPM / max 1319 PSI, with additional bores up to 8 in. 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.
