Making the diﬀerence – powershifing and power density
ZF exactly customized the 8 TX to the specific requirements for well servicing. 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 2,600 hp/1,912 kW and an input of up to 7,744 ft-lb/10,500 Nm. This makes it the transmission with the best power-to-weight ratio in the market.
Fulfilling our ambition
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 operates 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 electronic controls into the transmission. Additional optimizations such as an all aluminum housing make the ZF transmission the lightest transmission currently available in its class: It weighs only 2,806 lbs/1,273 kg including the coupling and without oil. Regardless of that, the 8 TX oﬀers a high level of flexibility: Two power take-oﬀs are also available. Also installation and removal of the ZF transmission is simplified thanks to its three lifting points, it can be safely and easily moved into its needed position.
