The Most Advanced Fluid Ends
Fluid Ends Since 1946
At Kerr Pumps, we know that the fluid end is the heart of pumping performance. We take great pride in our proven designs and manufacture the highest quality fluid ends. 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 tooling that mills a precise combination of taper, radius, and polish enabling a Kerr fluid end to outperform and last longer than the competition.
