The Gardner Denver PZ-11 SWFE 7500PSI is a heavy-duty mud pump built for high-pressure drilling fluid service. Factory data rates the pump at a maximum working pressure of 7500 PSI and a maximum flow of 587.7 GPM, with an 11 in stroke and a rated speed of 115 SPM. Output scales with liner selection: a 6 in liner delivers 464.4 GPM at up to 5317 PSI, a 5 in liner delivers 322.7 GPM at up to 7500 PSI, and a 4 in liner delivers 206.3 GPM at up to 7500 PSI. Performance figures are calculated at 90% mechanical efficiency and 100% volumetric efficiency, giving planners a dependable basis for matching the pump to each drilling program. We support the PZ-11 SWFE 7500PSI with fluid-end wear parts for operators and rig contractors across Canada, the United States and international oil and gas markets.
