High capacity dual output pump drive for demanding hydraulic systems
The TMP 255 is the strongest dual-output pump drive in this first product group. It is designed for demanding hydraulic applications where two pump circuits need to be driven from a single input, but where the power and torque requirements exceed the smaller TMP 240, TMP 241, and TMP 250 models.
Built with a cast iron housing, case hardened shafts, ball bearings, Viton oil seals, ground gears, and lubricated hubs, the TMP 255 gives engineers a robust platform for higher-demand hydraulic systems.
The TMP 255 is suitable for heavy mobile equipment, high-demand marine hydraulic systems, industrial power packs, and machinery where torque capacity, serviceability, and correct ratio selection are critical.
Key benefits
Highest capacity dual-output option in this group
With a datasheet motor reference of 610 kW and 305 kW per output, the TMP 255 is positioned above the TMP 250 for higher-demand dual-output applications.
Simplified ratio selection
The TMP 255 datasheet lists three ratio options: 0.818:1, 1.000:1, and 1.22:1. This makes it easier to focus selection around the main speed requirements rather than a broad ratio spread.
Lubricated hubs included
Lubricated hubs are listed as part of the standard equipment, supporting operation in heavy-duty applications.
Datasheet-supported fit checking
The TMP 255 datasheet includes dimensional drawings and a listed weight of 142 kg, allowing engineers to check space, mounting, and handling requirements before ordering.
