Oxygen Pumps

Customer: Medical Device Manufacturer
Application: Oxygen pumps

Issues:

  • Five stages of pressure increase
  • Exact pressures must be maintained to ensure correct function and safety

Solution

  • Each stage incorporated a piston with one Variseal® M, a V-spring energized piston seal made from Turcon® T07 and two wear sleeves made from QD8. 

The 5-stage pump is a key component for the filling of oxygen tanks in the home in a safe, compact manner. Oxygen must be charged to approximately 15.17 MPa / 2,200 psi. The solution provided by Trelleborg Sealing Solutions allowed for an efficient charging of oxygen with low power consumption. The seals passed all tests and have provide excellent service life.
