Low noise compact multiple stage
This pressure-balanced solution adds high efficiency and noise reduction to the high-torque capabilities of the compact GearMe design. Like the quiet operation, diminished flow pulsation and vibration also improve operator comfort.
Features and benefits
- Easy installation and machine design flexibility due to compact dimensions
- High torque transmission and working performance
- No need for secondary noise reduction measures
- Almost twice the number of teeth of a standard gear pump of the same frame size
- Reduced flow pulsation and vibration, which improves operator comfort
- Reduced noise emissions by up to 10 dB(A) on average compared with standard gear pumps
- Helps meet legal NVH (noise, vibration, harshness) requirements
Applications
- Tractors and wheel loaders
- Telehandlers
- Sweepers and rollers
- Combines and harvesters
- Excavators
- Cab-equipped mobile machines
- Forklifts and lift trucks
- Aerial work platforms

Notes:
- The rated and peak pressure mentioned in the table are only for pumps with flanged ports. When
threaded ports are required, a de-rated performance has to be considered. To verify the compliance of a high pressure application with a threaded ports pump, contact a Danfoss representative. - Also available with displacement 40 cm3 [2.44 in3] for lubrication.

Low noise two stage
Our two-stage option features internal splined drive shafts connected through a coupling and an intermediate steel plate. The two pumps are hydraulically independent, which saves space and enables the efficient control of distinct machine functions. Inlet ports can be shared or separate, and relief valves and optional process flow diagrams (PFDs) on the pump covers are available.
Low noise three stage
Our three-stage option features internal splined drive shafts connected through couplings and intermediate steel plates. The three pumps are hydraulically independent, which saves space and enables the efficient control of distinct machine functions. Inlet ports can be shared or separate, and relief valves and optional process flow diagrams (PFDs) on the pump covers are available.
