Less is more

The new Harmony® P3 pump by Otto Bock.

Die neue Harmony® P3 Pumpe von Otto Bock.

The Harmony® system, which stands for active volume management and improved adhesion, has established itself as the fitting standard for transtibial amputations.
For Otto Bock, this success is no reason to rest on its laurels: After further development work, the company is now presenting the new Harmony® P3 pump.


The new pump is smaller and, with a weight of just 400g, much lighter than its predecessor. This allows even more patients to benefit from the advantages of the Harmony® system. Reduced complexity is the key feature of the slim, purist design of the new pump.

The Harmony® P3 pump can be adjusted to the activity level and weight of each patient by the prosthetist and - if necessary - maintained on site.

This is made possible by the innovative function ring, which can be replaced in a few simple steps. The ring generates the required negative pressure and simultaneously acts as a dampening element and rotator - at each and every step.

The new Harmony® P3 pump is suitable for patients with mobility grade 2 through 4 and a body weight of 45 to 100kg.
