Parker M2A33912T20NB High-Speed Hydraulic Motor

Parker M2A33912T20NB High-Speed Hydraulic Motor – M2 Series

The Parker M2A33912T20NB Hydraulic Motor is a high speed, high performance hydraulic motor from the world famous M2 series. This gerotor style motor is precision built for longevity and can handle the demanding requirements of industrial, mobile and marine hydraulic systems. It has a small, robust construction that provides outstanding beginning torque, usually 90% of running torque, and smooth operation at all speeds. Whether you’re using it for fan drives, winch operations or vibratory systems, the Parker M2 series is the industry standard for reliability in high cycle, high speed applications.

Model Details & Compatibility

• MPN: M2A33912T20NB
• Compatibility: This unit adheres to global SAE mounting, shaft, and port dimensions. It serves as a drop-in replacement for legacy Parker M2 series units in diverse hydraulic circuits.
• Condition: New Unused Surplus
• Cross-References: Compatible with industry-standard hydraulic motor footprints within the Parker Nichols™ M2 product line.

Main Features

• High Starting Torque: Capable of up to 90% of operating torque for reliable operation under load.
• Precision Gerotor Design – Provides long service life and very quiet operation compared to ordinary vane or spur gear motors.
• Bi-Directional Operation: Internal relief checks protect the shaft seal from pressure spikes for flexible installation.
• Heavy Duty Seal System: Fitted with a high-pressure shaft seal capable of resisting back pressure (up to 400 PSI) without requiring a quick case drain.

Product Specifications: Parker Hannifin M2 Series

Installation Guide by NDMarineTech’s Engineer:

1. Case Flushing: Even though the M2 series has a strong shaft seal, always check your case drain line for obstructions when you are approaching the 400 PSI back-pressure limit.
2. Fluid Cleanliness: The gerotor design is susceptible to particulate contamination. Keep your hydraulic fluid at ISO 4406 cleanliness standards (preferably 18/16/13) to avoid scouring of the internal rotor sets.
3. Thermal Management: If operating fluid temperatures are more than 45°C (80°F) above ambient, contact factory for seal material compatibility (e.g. change to Fluorocarbon seals).
4. Startup “Burp”: When first commissioning, fill the case with clean hydraulic oil, manually rotate the motor shaft to ensure it is lubricated before the first system start.
5. Monitoring: The use of a thermal imaging camera on the motor casing during full load testing can be used periodically to identify internal wear or bypass problems early by means of localized hot spots.
