Evolutionary low noise patented gear pump technology
This low noise external gear pump guarantees outstanding performance throughout it's entire service life.
With a simple but sophisticated design, we offer a gear pump that not only is quieter. It also has a unique advantage over the most popular low noise gear pump. The patented design guarantees the pump will remain silent after many hours of heavy-duty operation. This offers costs savings over traditional gear pump by eliminating costs associated with external noise reduction devices.
The design offers up to 10 dB noise reduction over regular gear pumps. It is ideal for application where low noise and high efficiency are required. Typical applications include tractors, indoor lift trucks, aerial platforms, construction equipment, material handling, agricultural and lifting devices.

Space is limited on construction sites, and there are people working everywhere. Contractors need machines that can safely maneuver in a tight spot. At the same time they still need to be powerful enough to get the job done. At Danfoss, we deliver the components, software, and controls that enable your machines to run safely, efficiently and effectively.

Cranes and other large handling machines are required to operate within very specific load ranges. Danfoss provides pressure transmitters that supply load limiting systems with crucial data, safeguarding your equipment, your load, and your operator.

Rough, sloping terrain and cramped working conditions call for robust and reliable forestry machines. We make sure you can manage everything from cutting trees and transport to preparing the forest floor for replanting. We have the smart hydraulic solutions your machines need for precise and efficient forestry operations.

Think about the heaviest challenges in the open mining, road building and construction industry. Tasks such as cutting through rock or the Arctic permafrost; compacting thick layers of hot asphalt. As well as lifting huge, prefabricated wall panels into place.
