Overview

Benefits
The Harmony P4 HD (Heavy Duty) is rated for patient weights up to 330 lbs and is a line extension to our P4 mechanical vacuum pump line whose design is lighter, shorter and faster vacuum than existing pumps. The Harmony P4 HD also has vertical shock reducing pylon and torsion unit incorporated in addition to active vacuum volume management. The unique direct connection to the socket also eliminates any external tubing. With over 1" less clearance than other pumps more users can get fit with more foot options.

Harmony’s proven clinical benefits
  • Limb volume management1
  • Reduces pistoning between the limb and socket2
  • Improves residual limb health3
  • Helps improve balance, reduce risk of falls and improve walking4
