Danfoss TMT 470 151Z3013 orbital hydraulic motor

Danfoss TMT 470, part number 151Z3013, is a fixed-displacement orbital hydraulic motor for low-speed, high-torque drives. The factory geometric displacement is 477.3 cm³/rev. Nominal size 470 identifies the series size and differs from the exact geometric displacement.

The factory execution uses a cylindrical keyed shaft: Dia. 40 mm, M12 x 1.75-6H thread in shaft end. Refer to the original shaft-end or wheel-hub drawing for spline, key, threads and tolerances.

Mounting type: 4 Bolt - Square; locating pilot 160.0 mm; bolt circle 200.0 mm. Main port connection: 3/4" BSP. Drain connection: 1/4" BSP. Port arrangement: Sideport - staggered. The motor uses Geroler gearing and disc valve with valve drive. Factory check-valve provision: No.

Select the operating point from the size-specific hydraulic data and performance diagram. Continuous, intermittent and peak limits represent separate operating duties and must not be combined into one maximum-duty point. Differential pressure differs from maximum inlet pressure. Observe the applicable shaft loading, shaft-seal pressure, return pressure and drain requirements.
