POWER-SHIFT TRANSMISSIONS: PRESSURE PUMPING
Engineered for Long Life
Twin Disc transmissions for high-pressure oil and gas well pumping lead the industry in rugged dependability and high horsepower.
The 8500 Series power-shift transmission handles massive horsepower and torque loads with extraordinarily smooth power shifts, thanks to its torque converter-based architecture. Oil and gas field service companies and equipment makers worldwide choose the 8500 to pump cement, chemicals and water for fracturing and well workovers.
The 7500 Series is the “street legal” sibling of the 8500, at about two-thirds the size, weight and capacity. Transportation is easy on chasses that need no special highway permits. The 7500 shifts power using sophisticated electronic controls that automatically actuate shift points, versus the 8500’s continuous power management via torque converter.
