Danfoss TMVW 800 151Z8213 orbital hydraulic motor

Danfoss TMVW 800, part number 151Z8213, is a fixed-displacement orbital hydraulic motor for low-speed, high-torque drives. The factory geometric displacement is 801.8 cm³/rev. Nominal size 800 identifies the series size and differs from the exact geometric displacement.

The factory execution uses a wheel hub: Thread Hole Flange: 6 x M16 x 1.5 - BCD 170 mm [6.7 inch]. Refer to the original shaft-end or wheel-hub drawing for spline, key, threads and tolerances.

Mounting type: 8 Bolt - Wheel; locating pilot 223.9 mm; bolt circle 265.0 mm. Main port connection: 1 5/16-12 UN-2B SAE O-Ring port. Drain connection: 9/16-18 UNF-2B O-Ring port. 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.
