11009374 Danfoss TMT470 FLV Orbital Motor

Product Overview

The 11009374 is a Danfoss Power Solutions TMT 470 FL V orbital hydraulic motor, belonging to the large-displacement TMT Series of low-speed, high-torque orbital motors.

Danfoss PowerSource identifies 11009374 as TMT 470 FL V and publishes its complete model code. The official TMT technical manual covers the TMT, TMTU, TMTW, TMT FL and TMTW FL families and provides verified performance data from TMT250 through TMT630.

The TMT architecture uses a disc valve with valve drive, Geroler orbital gearwheel set, tapered roller bearings and a high-load output-shaft design. Danfoss highlights smooth running, constant operating torque, high starting torque, high return-pressure capability, high efficiency and robust construction across its orbital motor platform.

Danfoss’s current public information for the neighboring TMT470 FL configuration documents:

• 4-bolt square mounting
• Ø125 mm pilot
• Ø160 mm bolt circle
• 1-1/2-inch splined shaft
• G3/4 side ports
• G1/4 drain port
• G1/4 brake-release port
• Tapered roller bearings
• NBR shaft seal.

Because the current 11009374 page does not expose all configuration attributes, these neighboring FL configuration fields should not automatically be treated as a guaranteed complete decode of 11009374. The nameplate and original configuration record remain the final reference.

TMT FLV Brake and Flushing Configuration

Danfoss’s official TMT FL technical section specifies:

• Brake holding torque: 2,000 N·m
• Minimum brake release pressure: 13 bar / 190 psi
• Maximum continuous release pressure: 20 bar / 365 psi
• Maximum peak release pressure: 40 bar / 580 psi
• Brake release chamber bleed-off: approximately 0.65 L/min at 13 bar.

The TMT technical documentation also identifies flushing valve and higher-holding-torque brake arrangements as available features.

These are TMT FL/FLV family-level specifications. The exact brake and flushing configuration of 11009374 should be confirmed against its original configuration record before publishing a narrower option claim.

Control Configuration

• Motor type: Fixed-displacement LSHT orbital hydraulic motor
• Hydraulic distribution: Disc valve with valve drive
• Orbital gearwheel set: Geroler
• Displacement control: Fixed displacement
• Speed control: Hydraulic flow control
• Torque generation: Determined primarily by differential pressure and actual operating conditions
• Rotation: Controlled hydraulically through the motor ports
• TMT FLV: incorporates an independent hydraulic brake-release circuit.

Danfoss documents tapered roller bearings on TMT/TMT FL shafted motor versions for high radial and axial load capability.

Key Technical Advantages

High Low-Speed Torque Density

The TMT470 provides 1,760 N·m continuous torque, 2,420 N·m intermittent torque and 2,735 N·m peak torque under the published conditions. This makes the platform suitable for high-load LSHT drive systems.

Geroler Orbital Gearwheel Set

Danfoss identifies a Geroler orbital gearwheel set for TMT470, combined with a disc valve and valve drive to convert hydraulic flow and pressure into controlled rotary output.

Tapered Roller Bearings

The TMT platform uses tapered roller bearings capable of handling significant radial and axial loads. Danfoss’s shaft-load calculation is based on shaft speed, load position, mounting flange and rated torque rather than a single universal radial-load number.

High Pressure Capability

For TMT250–630, Danfoss specifies maximum inlet pressure of:

• 270 bar continuous
• 370 bar intermittent
• 420 bar peak.

These are not universal simultaneous pressure/flow operating points; the relevant function diagram must be checked for the actual motor.

High Return-Pressure Capability

With the appropriate drain-line configuration, the TMT family specifies maximum return pressure of:

• 140 bar continuous
• 175 bar intermittent
• 210 bar peak.

Integrated Brake and Flushing Platform

TMT FL systems provide hydraulic brake functionality, with official brake-release specifications and available flushing-valve configurations. This architecture can support load-holding and thermal/oil-management requirements in demanding mobile equipment.

Multiple Mechanical Configurations

Danfoss offers multiple TMT, TMTU, TMTW and TMT FL/TMTW FL mounting and shaft configurations, including 4-bolt flanges, European/US versions, splined shafts, cylindrical shafts, tapered shafts and wheel configurations.

Application Areas

Typical TMT applications include:

• Heavy-duty mobile machinery
• Road construction equipment
• Agricultural machinery
• Forestry equipment
• Material-handling equipment
• Conveyor drives
• Winch drives
• Rotary drives
• Wheel-drive systems
• Industrial auxiliary drives
• Heavy-duty drum drives
• Mobile off-highway equipment

Danfoss positions its orbital-motor platform for demanding mobile off-highway conditions and highlights high starting torque, robust construction and substantial radial/axial bearing capacity.

Expert Maintenance Tips

Manage the Drain Circuit

Danfoss provides specific TMT drain-flow and return-pressure data and stresses correct drain management. High-displacement TMT motors should not be evaluated only by A/B port pressure.

Monitor Return Pressure

Excessive return/case pressure can adversely affect the shaft-seal system even when the main hydraulic pressure remains within its rating. Always verify the applicable return-pressure limit.

Control Hydraulic-Oil Viscosity

Danfoss’s TMT function-diagram test conditions use mineral hydraulic oil at 35 mm²/s / 165 SUS and 50°C / 120°F, with return pressure between 5 and 10 bar / 75–150 psi. Actual field performance changes with oil viscosity and temperature.

Avoid Continuous Operation at Intermittent or Peak Ratings

Danfoss specifies intermittent values for a maximum of approximately 10% of each minute and peak values for approximately 1% of each minute. Maximum flow and pressure must also be evaluated using the specific motor function diagram.

Calculate External Shaft Loads

Because TMT motors use tapered roller bearings, significant radial and axial loads can be supported. However, allowable radial loading depends on shaft speed, load position and mounting geometry and should be calculated for the actual machine.

Verify the Brake Circuit on FLV Models

For FL/FLV configurations, separately verify:

• Brake-release pressure
• Brake-line restriction
• Drain pressure
• Holding torque
• Brake-release response
• Oil temperature

The standard FL brake data specify 13 bar minimum release pressure, 20 bar continuous release pressure and 40 bar peak release pressure.

Verify the Complete 11009374 Configuration

For 11009374, verify the complete model code rather than selecting the motor only by “TMT470 FLV”. Confirm:

• Complete model code
• Mounting flange
• Pilot and bolt circle
• Shaft configuration
• Shaft spline
• Main-port thread
• Drain port
• Brake-release port
• Shaft seal
• Gearwheel set
• Flushing configuration
• Rotation
• Installation length
• Weight

Danfoss currently publishes the complete model code for 11009374, but its public PowerSource page does not expose all attribute fields. The original nameplate and configuration record therefore remain the final replacement reference.

100% Simulated Working-Condition Testing

A replacement TMT470/TMT470 FLV validation process should include:

• No-load startup
• Forward/reverse rotation
• Low-speed stability
• Rated-flow testing
• Continuous pressure-drop testing
• Intermittent pressure-drop testing
• Brake-release verification
• Drain-flow/return-pressure verification
• External leakage inspection
• Shaft running-condition inspection
• Flushing-function verification where applicable

This gives your 100% Simulated Working-Condition Testing claim a concrete engineering basis.
