Power through Efficiency

Dual displacement

Dual Displacement motors are able to offer High Torque and High Speed performance with a more effective and efficient use of the power available. They are available in five cylinder BD format and seven cylinder TD format covering a wide range of displacements.

Change of displacement can be made hydraulically or electronically and can be done with the motor stationary or in motion. The ratio of displacements can be 2:1, 3:1, 4:1 or even 1:0. Due to the variation of displacement being by altering the crankshaft stroke the motor retains it’s high efficiecy even in low displacement mode.
