SPX Back-Up Rings for High-Pressure Homogenizers

SPX back-up rings are critical components in the sealing systems

of high-pressure homogenizers. Designed to support primary seals and prevent

extrusion under extreme pressure, back-up rings play a vital role in maintaining

machine reliability and operational stability.

BOS Homogenisers supplies high-quality SPX back-up rings for SPX, APV,

Gaulin and Rannie homogenizers. With over 75 years of experience in

homogenisation technology and a worldwide distribution network,

BOS Homogenisers ensures reliable spare parts supply for demanding

industrial applications.

What Are SPX Back-Up Rings?

Back-up rings are auxiliary sealing elements used in combination with

O-rings, packings and other primary seals. In SPX homogenizers, these

components operate in environments where pressures are extremely high

and mechanical loads are continuous.

The primary functions of SPX back-up rings include:

Tiivisteen puristumisen estäminen korkeassa paineessa
Supporting the structural integrity of primary seals
Maintaining proper sealing geometry
Reducing deformation of elastomer components
Tiivisteiden kokonaiskäyttöiän pidentäminen

Without properly specified back-up rings, sealing systems can fail

prematurely, resulting in leakage, contamination risks and unplanned downtime.

Applications in SPX Homogenizers

SPX homogenizers, including APV Gaulin and Rannie models, are used

in dairy, beverage, pharmaceutical, chemical and biotech industries.

These machines operate under high pressure and require robust and

precisely engineered sealing systems.

SPX back-up rings are commonly used in:

Mäntätiivisteyksiköt
Nestepään sylinterilohkot
Hydrauliset käyttöjärjestelmät
Korkeapaineventtiilikokoonpanot
Pressure relief systems

Each back-up ring must match the homogenizer model, pressure rating

and process conditions to ensure reliable performance.

Suunniteltu korkeapaineisiin olosuhteisiin

High-pressure homogenization subjects internal components to extreme

mechanical stress. SPX back-up rings must withstand:

Jatkuvat painejaksoja
Rapid pressure fluctuations
Thermal expansion and contraction
Exposure to various process media
Dynamic movement of adjacent components

Dimensional accuracy and material consistency are essential to prevent

seal extrusion and maintain long-term sealing performance.
