AN EXPERT'S TAKE ON CAT® CUBE BORE

Fluid ends are constantly under harsh stress and pressure. Caterpillar has taken this seemingly permanent problem and engineered new cube bore fluid end technology to solve the problem. By reinventing the design of the internal bore of a valve fluid end, peak loading stresses within a fluid end have been lowered by over 50% with testing showing results of a lifespan over three times the standard fluid end technology.

 

“Caterpillar is really excited to bring the next generation of pumps to the field. We really feel we have the right product to lower your maintenance cost and increase your uptime.”

 

The Cat® Cube Bore design takes the internal four corners of a fluid end and stretches them out, elongating the area that sees the stress within the fluid end. The new design not only changes the internal geometry of the fluid end but also increases life of the product by maximizing material specifications and after-hardening processes such as autofrettage and shot peening.

 

New Cat® Fluid End Design Extends Block Life by 50% by eliminating one of the most common causes of fluid end failure — fatigue cracking at the intersection of the bores.
