4R220 Dynamic Vacuum System Pump

The Dynamic Vacuum System is an active vacuum system that combines innovative technology with ease of use for both technicians and users.

• Unlike passive (valve) systems, the Dynamic Vacuum System not only generates a vacuum in the swing phase but also in the stance phase.
• The prosthesis fits more firmly on the residual limb thanks to this vacuum, which improves the person’s perception of the ground beneath them.
• Installation is simple: all common plaster casting techniques can be used and no certification is required.
• Thanks to its low weight of 210 g and the low system height of 37 mm, the Dynamic Vacuum System is easy to integrate into the prosthesis solution.
• The pump consists of a cylinder body, a magnetic piston and one-way valves.
• The complete Dynamic Vacuum System requires the 4R220 pump, the special 6Y94 liner and a sealing sleeve (such as the 453A3 ProFlex).
