Catalog excerpts

Cartridge Kit for High Torque Vane Motor • The HM series cartridge kit is interchangeable with Vickers vane motor. It consists of a cam ring, rotor, 10 vanes, and 2 pressure plates. The cartridge is bolted together so parts can be serviced separately or as an assembly. A cartridge can be replaced without removing the unit from the machine, and usually without disconnecting the lines. • To change rotation, reverse the motor ports. No need to do anything with the cartridge. Ordering Code Vane Type Motor (Externally Drained) Ring Size - Nominal torque Rating
