Robust Lightweight for Oil and Gas Production with Newly Developed 8 TX Automatic Transmission by ZF

Pumping systems used for oil and gas production have to provide a particularly constant pumping capacity. Unintended speed fluctuations can destabilize both intake volume and delivery pressure which presents a risk to the entire drill hole in the worst case. All the more important it is to have transmission systems which guarantee a constantly smooth operation and thus minimize risk factors.

ZF exactly customized the new 8 TX to these specific requirements. It offers eight gears and particularly harmonious gear transitions as well as a high spread of gear ratios. Together with the very robust basic design, this minimizes both component stress and wear and results in a reliable, durable transmission with very low life cycle costs. More than anything else, it ensures a precise control of the pumping station. The latter can be highly powerful with the new ZF automatic transmission because the 8 TX has been prepared for a power of 2 500 hp and an input of up to 10 500 Nm.What makes it literally unique, however, is its special design: Thanks to state-of-the-art BUS communication and modular programming possibilities, the ZF transmission does without a torque converter. Trouble-free continuous operation is ensured by a flexible coupling with the latest damping technology which prevents the transfer of engine vibrations. Furthermore, the 8 TX dissipates less heat thanks to its sophisticated design.

ZF integrated the complete control electronics directly into the transmission. Additional optimizations such as a clutch housing of aluminum make the ZF transmission the lightest transmission currently available in its class: It weighs only 1 350 kg in a dry condition, including the clutch. Furthermore, it is of a very compact dimension with a length of 1.490 mm and a height of 850 mm. Regardless of that, the 8 TX offers a high level of flexibility: Two power take-offs are also available. Also assembly is simplified with the ZF transmission because, thanks to its three-point linkage, it can be easily and precisely moved to the requested position.

The development of the new transmission for pumping stations is at the same time a good example of the outstanding engineering work within the ZF Group: The developers have presented the currently close-to-production product only three years after the original idea. Furthermore, ZF's engineers have managed to make the 8 TX economical in every respect despite its high technical requirements. Now it completes the ZF transmission portfolio for applications in the oil and gas industry. However, customers are benefiting from more than the products only: Also the know-how and support of one of the global leaders in driveline and chassis technology are available to them in the form of 650 service stations around the globe.
