M3-M4 Fixed Displacement
The M3 and M4 Series vane motors
are fixed displacement and designed
especially for severe duty applications.
The balance vane cartridge
concept provides high volumetric
efficiency, longer life, lower noise,
and a high starting torque efficiency.
The double motor is ideal for
applications to obtain three speed
operation.
