“At Caterpillar, our goal is to provide the most reliable and durable power
solutions for the Well Service and Pressure Pumping market. By adding the well
stimulation pumps to our portfolio of offerings we are able to provide a more
comprehensive pressure pumping solution for our customers,” Mark Helgren,
Caterpillar Global Petroleum  integration manager, stated. “Our customers, who
have been pleased with our engines and transmissions, will be able to readily
implement the Cat well stimulation pumps into their operations with the utmost
confidence in their performance and Cat Dealer support.”

The Cat Well Stimulation Pumps feature fluid ends and power ends designed to
an industry standard footprint. This will allow customers to easily fit the
Cat pump into their existing trailer designs. In addition to the standard
fluid end Cat will offer an Extreme Duty (XD) fluid end with superior
durability for the harshest operating conditions. The fluid ends on both
models have a valve-over-valve design to simplify valve, seat and plunger
installation, and each fluid end block is manufactured with a robust material
conditioning process. A full assortment of discharge flanges, suction
manifolds, and bore sizes will also be offered.

The new Cat well stimulation pumps will be distributed, sold and supported
through the worldwide Cat dealer network with trained technicians to ensure
service support is never out of reach. For more information, please visit the
well stimulation pump website or stop by the Caterpillar booth at OTC Houston,
