Caterpillar introduces new transmission for well fracturing

Cat® CX48-P2300 is lightest frac transmission available


Houston, TX – Caterpillar, Inc., introduced today its new Cat® CX48-P2300 transmission, designed specifically for hydraulic fracturing associated with well stimulation and completion.  Weighing in at 3,530 pounds (1,601 kg), the CX48-P2300 is the lightest weight transmission available for frac applications.

With an input power of 2,300 bhp (1,716 bkW) and peak input torque of 6,656 lb-ft (9,024 N∙m), the CX48-P2300 also features improved durability to match engine life, and an industry-high horsepower-to-weight ratio. Its cutting-edge controls are tailored for the frac market, with a focus on safety and flexibility. The starter interlock feature ensures the engine cannot be started while the transmission is in gear, and the quick-to-neutral switch allows the operator to put the transmission in neutral immediately.

“We designed this petroleum transmission for the specific needs and demands of heavy well fracturing applications,” said Carl Thiele, Caterpillar Global Petroleum technical sales manager. “This transmission offers increased reliability and durability, and yet is simple to install and maintain, resulting in lower owning and operating costs, and reduced downtime – all things that are of utmost importance to our customers.”

Features enabling the simplified installation and maintenance include an integral PTO; integral filters with bypass indicator; reduced external hoses; rigid-mounted ECU with wire harness and remote mount capability; low oil level indicator and oil pressure monitoring.

The performance of the CX48-P2300 was built around the success of the TH55’s advanced controls. Its eight usable gears allow it to come online quickly and eliminate damaging engine harmonics at low speeds.
