Harmony vacuum pump

Active volume management

Secure prosthesis support

The Harmony is a modern closure system. It ensures that the artificial limb is securely connected to the residual limb.

Active vacuum systems, such as the Harmony, pump out virtually all the air between the liner and socket, thereby regulating the vacuum in a defined range. The system is individually adapted to the needs and activity level of the respective user. In addition to a secure connection between the socket and artificial limb, the system stabilises the residual limb volume. High adhesion also improves control of the artificial limb.

The Harmony system is available as the mechanical Harmony P3 pump, which regulates the vacuum at every step according to the stride rate and load using a function ring. It is suitable for below knee amputees.

Compact housing

Thanks to the compact design, the Harmony P3 is slim and lightweight.

Functional ring

The elastomer ring generates a vacuum, ensuring vertical shock absorption and enabling natural torsion. Thus, it absorbs forces which could otherwise affect the residual limb.



Benefits at a glance

Firm hold

The Harmony keeps the artificial limb securely in place. The residual limb, liner and socket form a unit and you gain control thanks to full contact with the artificial limb. You feel immediately when your prosthetic foot touches the ground, which makes walking safer and more controlled for you.

Volume management

You know that the volume of your residual limb can change in the course of the day. The Harmony prevents these volume fluctuations and your artificial limb is always securely seated.

Integrated shock absorption.

With the mechanical Harmony P3 pump, the function ring provides comfortable shock absorption – at every step you take. It permits natural rotation movements that occur automatically when you walk, while forces that act on the residual limb while walking are significantly reduced.

Triton Harmony

The Triton Harmony carbon foot combines the high functionality of the Triton feet with the Harmony technology: numerous users are convinced by a smooth rollover, outstanding energy return that conserves energy while walking and safety even on rough terrain, combined with an active vacuum thanks to Harmony.
