Denison vane motors
Working with 12 vanes and a patented cartridge design, those motors allow a very low noise level, whatever the speed, and exhibit a very low torque ripple. Vane motors begin life with a high volumetric efficiency, and maintain that efficiency throughout their operating life.
Vane pin holdout design improves the mechanical efficiency at low pressure. The high starting torque efficiency of the vane type motors allows them to start under high load without pressure overshoots, jerks and high instantaneous horseppower loads. The vane, rotor and cam ring are pressure balanced to increase life overthe full speed range.
