Dawopu offers a complete line of fluid end modules and components that are manufactured to OEM specifications and interchangeability. We offer 7500 psi designs for all major pump configurations. Our Caliber® modules start with high-tensile strength steel and are machined to precise engineering tolerances.
Each forging is machined and heat treated to maintain the best physical properties inside the module and on the surface, thus minimizing washing and stress cracking.
Caliber F-7500 2-Piece Design
F-1600 Compatible Fluid End Modules
The 2-piece 7500 psi fluid end module for the F-1600 pumps is based on industry-standard design and is 100% compatible with parts from the OEM and other manufacturers.
