Dynamic Vacuum System – a small pump with a big impact

The Dynamic Vacuum System (DVS) combines innovative technology with ease of use. Magnetic coupling occurs between the liner and the pump as soon as the user steps into the socket with the liner fabricated especially for this pump. A permanent vacuum is generated after just a few steps. Two versions are available: the 4R220 with a 4-hole connection for a simple prosthetic alignment. Additional distal adapters are not required. The 4R220=1 is a non load-bearing version which allows greater freedom in the prosthetic alignment.

  • All common plaster casting techniques can be used, and no certification is required
  • Permanent vacuum in just a few steps
  • Fits very well into overall look of prosthesis thanks to low structural height

Easily replaceable spare parts

Spare parts for the Dynamic Vacuum System can be easily replaced by the O&P professional.

Piston and Dynamic Vacuum System liner
Magnetic connection

The piston of the Dynamic Vacuum System connects to the liner with a magnet. This makes it easier to don the prosthesis.

Sealing ring of the Dynamic Vacuum System.
Protected against dirt

The Dynamic Vacuum System is completely sealed to prevent dirt from penetrating. This is ensured both by the insert ring and the valves.

4-hole connection of the Dynamic Vacuum System.
4-hole connection

The prosthesis can be easily assembled using the integrated 4-hole connection (via the direct installation of distal adapters).

Die Pumpe des Dynamic Vacuum Systems besteht aus einem Zylinderkörper, einem magnetischen Kolben und Einweg-Ventilen. Es ist aus hart-coartiertem Aluminium gefertigt.
