A New Line of Pump Drives FROM TWIN DISC

Twin Disc is pleased to offer a new line of pump drives to meet your hydraulic system needs. These drives are available in a wide variety of gear ratios, including both speed increasing and reducing configurations.

The modular design of these pump drives enables you to choose from a variety of input options including a flex plate, rubber block drive, or clutch to match your SAE engine flywheel dimensions. Independent mounting is also an option, both direct or with a clutch.

For your pump mounting requirements, Twin Disc offers standard SAE adaptor kits as well as a wide variety of non-SAE adaptations for your special needs.

With models having one, two, three, four or six pump pads, Twin Disc is sure to have a pump drive to complement your hydraulic application. For your convenience, the number of pump pads is indicated by the first numeral after the "AM" designation in the pump drive model numbers. Models AM 232, AM 365, AM 450, and AM 480 also have additional pump pads available on the input side of the pump drives.

TWIN DISC PUMP DRIVES INCLUDE THE FOLLOWING DESIGN FEATURES

? Cast iron housings ? Case hardened and ground spur gears, except AM 216--AM 320 series

where gears are shaved ? Ball bearings ? Case hardened shafts ? Viton seals on input shaft ? Output rotation opposite the direction of input rotation ? Gear ratios identical on all outputs ? Maximum input torque based on theoretically unlimited gear life and a

minimum L10 bearing life of 10,000 hours
