Caterpillar to Unveil Well Stimulation Pumps at OTC 2013

Houston, TX – Caterpillar Global Petroleum is pleased to announce the launch of Cat® Well Stimulation Pumps for the well service market. Starting in May 2013, Caterpillar will begin accepting orders for the Cat WS223, a 2250 bhp (1678 bkW) triplex well stimulation pump, as well as the Cat WS255, a 2500 bhp (1864 bkW) quintuplex well stimulation pump. In addition to offering the complete pump for well service customers, Caterpillar will offer a variety of 8” and 10” stroke fluid ends individually. A 2700hp triplex pump, available in late 2013, will be on display along with several fluid end models at the Caterpillar booth #3341 at OTC 2013, May 6th – 9th in Houston, Texas.

“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.
