Harmony P4 – faster, shorter, lighter

Faster, shorter, lighter: these goals were realised in the development of the P4 pump. 
Faster: thanks to novel double-stroke technology, the required vacuum is reached after just a few steps.
Shorter and lighter: the Harmony P4 is integrated directly into the socket. Additional adapters are eliminated in favour of the structural height and overall weight. An external hose is no longer necessary. 
Mechanical Harmony pumps have built-in impact absorption and a torsion function. This supports active prosthesis users in particular.

  • Fast vacuum thanks to double-stroke technology
  • Low structural height thanks to direct integration into the prosthetic socket
  • Built-in shock absorption and torsion function
  • HD version: suitable for a body weight of up to 150 kg
