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.
