Stronger. Tougher. Super.

Introducing SUPER STAINLESS II™ from Kerr Pumps. Our new, patent-pending SUPER STAINLESS II™ is the strongest stainless steel ever used in a frac fluid end. Avoid wash and wear in your frac fluid ends with SUPER STAINLESS II™ by Kerr Pumps.

A Super Material.

Sometimes to take a major step forward, you have to completely change directions. We wanted to use a material that could withstand the most extreme pressure pumping environments. Super Stainless™ is a state-of-the-art material offered exclusively by Kerr Pumps. This super material has the chemical properties to hold up to extreme corrosion and mechanical properties that are off the charts. This unique blend of premium stainless steel is forged to frac.

Extraordinary by Design.

Super Stainless™ fluid ends are designed for high performance. With enhanced internal geometries we have been able to smooth the flow throughout the fluid end. This decreases turbulence in the system and increases fluid end life. By using finite element analysis we were able to pinpoint weaknesses in traditional fluid ends and beef up our new Super Stainless™ fluid end. This increased block size helps support the fluid end during high stress pumping applications.

Advanced Manufacturing.

Manufacturing high quality fluid ends is what we really do best. The tolerances achieved by our CNC machines are equal to or better than anyone in the industry. To achieve the smoothest flow, each forging is precision machined with our proprietary tools that mill a precise combination of taper, radius and polish enabling a Super Stainless™ fluid end to outperform and outlast the competition.
