Twin Disc Transmission excels in well stimulation.

Press Release Summary:




Featuring counter shaft design, TA90-7601 Power Shift Transmission offers expected L10 life of 10,000 hours. Coaxial, 9-speed unit can be power shifted under all loaded or unloaded conditions without any throttle dipping within range-to-range shifts. Flexible coupling allows transmission to be installed on engine's dry flywheel housing, minimizing torsional excitations by engine and pump. Transmission has max gross input power rating up to 1,939 kW (2,600 hp) at 1,900 rpm.

Twin Disc Transmission Excels in Well Stimulation



Twin Disc has announced the release of its TA90-7601 power shift transmission. This industry-leading unit outclasses the competition for use in triplex and quintuplex pressure piston gas and oil well stimulation. Due to its strong, yet simple counter shaft design, the unit has an expected L10 life of 10,000 hours to match the overhaul schedule of the engine that powers it.



The coaxial, nine-speed TA90-7601 has been designed to be power shifted under all loaded or unloaded conditions without any throttle dipping within range-to-range shifts. The smallest and most evenly-spaced gear ratio steps in the industry ensure that well pressure is maintained without any drop during gear shifts. A flexible coupling allows it to be installed on an engine's dry flywheel housing, reducing torsional excitations by the engine and pump. The transmission has a maximum gross input power rating up to 1,939 kW (2,600 hp) at 1,900 rpm.



Two 149 kW PTOs are available to power the hydraulics that drive the cooling fans and other auxiliary equipment. Because the transmission does not require a torque converter, mobile platform weight is reduced. A Twin Disc TA90-7501 transmission can be retrofitted to a TA90-7601.



The transmission was developed for use with Twin Disc's TDEC-500 electronic shift control. Included with the transmission, the system features built-in flexibility to modify the operation for different site- and rig-specific conditions, allowing optimized gear shift performance for absolute control of the piston pump. The shift control features an optimized line test mode specifically for the TA90-7500 and TA90-7600 families of Twin Disc power shift transmissions. The TDEC-500 unit has been environmentally tested to the highest industry standards.



Twin Disc manufactures off-highway transmissions, control systems, power take-offs, and mechanical, hydraulic and modulating clutches. Its products are designed and built to reliably perform under the harshest and most demanding work conditions.
