Product catalog summary

Overview

The WhiteDrive WD series hydraulic motors are engineered for light duty applications requiring high torque and efficiency. Featuring a compact design with integral check valves and case drain provisions, these motors reduce internal seal pressure to extend product life. They are suitable for diverse industrial and mobile uses including car wash brushes, food processing, conveyors, agricultural machinery, sweepers, and skid steer attachments.

Specifications and Performance Parameters

Displacement Range: 25 cm³/rev to 400 cm³/rev (1.5 to 23.5 in³/rev)
Maximum Speed: Up to approximately 1500 rpm continuous, varying by model
Maximum Flow: 150 to 1361 lpm (40 to 360 gpm) depending on displacement
Maximum Torque: Up to 582 Nm (5151 lb-in) intermittent
Maximum Pressure: Continuous up to 138 bar (2000 psi), intermittent up to 225 bar (3260 psi)

Performance data is based on testing at 45°C (113°F) with oil viscosity of 46 cSt (213 SUS). Intermittent ratings should not exceed 10% of total operation time.

Features and Benefits

Integral check valves enhance versatility and extend seal life.
Multiple mounting and shaft options provide design flexibility.
Spool valve design ensures smooth operation across wide speed and torque ranges.
Integral rotor design delivers smooth performance with compact size and low weight.
Low port profiling suits installations with limited space.

Typical Applications

Commonly used in agricultural equipment, conveyors, car washes, sweepers, food processing machinery, grain augers, spreaders, feed rollers, augers, and brush drives.

Performance Data and Graphical Summaries

Detailed displacement performance charts correlate flow rate, torque, speed, and pressure with efficiency zones (70-100%, 40-69%, 0-39%). Key insights include:

Theoretical torque increases with displacement and pressure.
Specified maximum intermittent and continuous torque and speed ratings per displacement size.
Highest efficiency typically occurs at moderate speeds and loads.
Rotor widths range from 4.1 mm (25 cm³) to 16.8 mm (125 cm³), indicating compactness.

Operational Guidelines and Limitations

Intermittent operation must not exceed 10% of total operating time to prevent premature wear.
Performance may vary slightly between production units.
Operating temperature and oil viscosity conditions are standardized; deviations may affect performance.

Mechanical and Dimensional Data

Rotor widths range from 20.8 mm (0.820 in) to 52.1 mm (2.050 in) depending on displacement.
Mounting options include 2-hole SAE A mounts, 4-hole square mounts, and manifold ports with NPT, UNF, or G threads.
Shaft options include splined shafts (7/8" 13 tooth, 1" 6B spline), straight shafts, extended shafts, and shafts with pinholes or woodruff keys; max torque ratings up to 678 Nm (6000 lb-in).
Shaft seal pressure limits and bearing load capacity curves are provided to ensure rated seal life and avoid oil starvation or overheating.
Motor weights range from approximately 5.2 kg (11.5 lb) to 6.88 kg (15.2 lb), with overall length varying by housing and pilot size.

Ordering and Configuration

Series selection between 145 and 146 with displacement options from 25 cm³/rev to 400 cm³/rev.
Multiple mounting flange and port configurations to suit application needs.
Bi-directional motor rotation; reversing inlet hose reverses shaft rotation.
Additional options include speed sensors (single/dual with various connectors), slinger seals, check valve configurations, and paint finishes.

Critical Parameters and Recommendations

Intermittent pressure ratings must not exceed 10% of operation time to avoid damage.
Adherence to shaft seal pressure and bearing load limits is essential for motor longevity.
Use recommended oil viscosity and lubricity to maintain proper lubrication and performance.
Dimension and weight data exclude paint thickness, which can add up to 0.13 mm (0.005 in).
Extended shafts are recommended when using speed sensor options for protection.

Additional Options

Shaft Options: Multiple shaft configurations identified by codes (e.g., 01, 02, 04, 10, 12, 15, 16, 30, 53, 66, F31, F37, B1, G8) for various application needs.
Paint Options: Two paint finishes designated as 'A' and 'B'.
Valve Cavity / Cartridge Options: Available but specific details not provided in excerpt.
Add-On Options: Codes A, W, X, Y, Z represent additional features or accessories.
Miscellaneous Options: Codes AA, AC, BE, FB, 146, and A cover other configurable features or special requirements.
