Comparing Torque Converters: Single Stage vs. Three Stage

Sep 8, 11 • Torque ConvertersComments Off on Comparing Torque Converters: Single Stage vs. Three Stage

Here at K&L Clutch, we’re proud to offer a comprehensive line of torque converters for a broad variety of industries, from some of America’s leading industrial clutch manufacturers, including:

Twin Disc Torque Converters
Allison Torque Converters
Manitowoc Torque Converters
Clark Torque Converters

But not all converters are the same. For example, let’s take a look at the differences between single-stage torque converters and three-stage torque converters:

Single Stage Torque Converters

The beauty of single-stage converters is their tough, reliable simplicity. Each converter consists basically of three elements: the turbine, the stator, and the impeller. Single-stage converters come in two types of housing — stationary and rotating. Depending on the model, single-stage torque converters boast a variety of capabilities: Sumpless single-stage converters with PTO drives are ideal for applications with power-shift transmissions and driving auxiliary hydraulic pumps. High-torque ration converters with stationary housing feature extraordinary hoisting and lowering capabilities. Type Four hydraulic converters are designed specifically for the oil and gas industry.

Three Stage Torque Converters

Three-stage torque converters employ three rings of turbine blades, as well as two sets of reactor or stator blades. The effect of this design is increased torque — up to five times the amount of engine output torque, in fact, when the engine is at a stall. Depending on the specific design, three-stage converters are rated for a range of engines, including 335 hp at 2400 rpm, 420 hp at 2200 rpm, and 580 hp at 2,200 rpm. Three-stage converters also come with both stationary and rotating housing.
