The Gardner Denver PZL-B 7500PSI GD HD is a high-pressure mud pump whose factory data lists a maximum working pressure of 7500 PSI at a rated speed of 115 SPM, with liner sizes stepping down from a 6 in liner rated to 5317 PSI to a 5 in liner rated to the full 7500 PSI. The fluid end module is the core pressure-bearing component: it is forged from high-grade high-strength alloy steel and put through an autofrettage process, a cold-work hardening treatment in which the bore is pressurized beyond operating levels so the inner wall retains beneficial compressive stress. That residual stress field works like a built-in shield against the tensile stresses of pumping, slowing fatigue crack initiation and growth. Production is governed by an API 7K quality framework with non-destructive testing, giving predictable, long module service life. We supply fluid-end parts for this model to Canada, the United States and international oil and gas customers.
FAQ
What pressure and speed is the Gardner Denver PZL-B 7500PSI GD HD rated for?
Factory data lists a maximum working pressure of 7500 PSI at a rated speed of 115 SPM. A 5 in liner carries the full 7500 PSI rating, while a 6 in liner is rated to 5317 PSI.
What does the HD fluid end module mean for service life?
The module is forged from high-strength alloy steel and treated by an autofrettage process that preloads the bore wall with compressive residual stress. This counteracts pumping tensile stress and markedly slows fatigue crack initiation and growth, extending module life.
What quality controls apply to these fluid end modules?
Modules are produced under an API 7K based quality system with non-destructive testing, so each module is verified sound before dispatch and its service life is more predictable in the field.
Which replacement parts do you offer for the PZL-B 7500PSI GD HD?
We supply fluid end modules plus the full wear set: liners, pistons, valves, valve seats, valve springs, packing and fluid end repair kits, sized to the liner bore and pressure duty of your pump.
Do you export PZL-B 7500PSI GD HD parts to Canada and the United States?
Yes. We ship to Canada, the United States and international oil and gas markets under HS code 84139100, with export packing and documentation arranged for smooth customs clearance.
