Twin Disc announces the TA90-7601 transmission specifically designed to meet the heavy-duty demands of driving triplex and quintuplex piston pumps for high pressure oil and gas well stimulation while matching the life of the diesel engines that power the rigs.
- Maximum gross input power rating up to 1,939 kW (2,600 hp) at 1,900 rpm
- Does not require throttle dipping for any of the range to range shifts; designed to be power shifted under all loaded or unloaded situations
- Lightweight yet durable aluminum housings to reduce overall vehicle weight
- Does not require torque converter
- Compact size enables it to fit between frame rails of mobile equipment
- Overall length of 1,851 mm (72.9 in.)
- Small, evenly spaced gear ratio steps ensure well pressure does not drop during gear shifts
- Simple plumbing eases installation
- Two live PTOs rated 149 kW
- Highly flexible coupling reduces damaging effects of torsional excitations by the engine and piston pump
- Internal brake capability to hold the output shaft when not pumping
- Oil fill port accessible from ground; sight glass in same location
- Remote mount filters with electronic bypass indicators
