BOS Homogenisers Back-Up Rings for High-Pressure Systems

BOS Homogenisers back-up rings are precision-engineered

components designed to support sealing systems in high-pressure

homogenizers. In demanding industrial applications, back-up rings

prevent seal extrusion, maintain sealing geometry and contribute to

stable and reliable machine performance.

As a specialized manufacturer and spare parts supplier,

BOS Homogenisers provides high-quality back-up rings

for BOS MG-series homogenizers as well as compatible Gaulin,

SPX-APV and Rannie machines. With more than 75 years of experience

in homogenisation technology and worldwide distribution, we ensure

reliable spare parts supply for critical production processes.

What Are BOS Homogenisers Back-Up Rings?

Back-up rings are auxiliary sealing elements used together with primary

seals such as O-rings and packing assemblies. In high-pressure

homogenizers, sealing systems are exposed to extreme operating

pressures and continuous mechanical loads.

The primary functions of BOS Homogenisers back-up rings include:

• Verhindern des Herausdrückens von Elastomerdichtungen unter hohem Druck
• Supporting structural stability of primary sealing elements
• Maintaining sealing integrity during pressure cycles
• Reducing deformation caused by mechanical stress
• Extending the service life of the entire sealing assembly

Without properly specified back-up rings, sealing systems may

experience premature wear, leakage or unexpected failure.

Applications in BOS MG-Series Homogenizers

BOS Homogenisers manufactures a complete range of MG-series

high-pressure homogenizers, designed for industrial use in dairy,

food, pharmaceutical, chemical and biotech sectors. These machines

operate at high pressures and require durable, precisely engineered

sealing components.

BOS Homogenisers back-up rings are used in:

• Kolbendichtungsbaugruppen
• Zylinderblöcke für den Flüssigkeitsbereich
• Hydraulic actuation systems
• Hochdruckventilgehäuse
• Pressure control systems

Each back-up ring is selected to match the pressure rating,

machine configuration and application requirements of the

specific MG-series model.

Engineered for High-Pressure Performance

Bei der Hochdruckhomogenisierung werden die inneren Bestandteile

to continuous stress and rapid pressure fluctuations. Back-up

rings must withstand:

• Extreme Betriebsdrücke
• Thermal expansion and contraction
• Mechanische Schwingungen
• Exposure to process media
• Dynamic movement of sealing components

Precision manufacturing and strict dimensional tolerances

are essential to ensure consistent sealing performance

and long-term reliability.

Compatible with Gaulin, SPX-APV & Rannie Systems

In addition to supplying parts for BOS MG-series homogenizers,

BOS Homogenisers specializes in spare parts for Gaulin, SPX-APV

and Rannie machines. This allows customers operating mixed

homogenizer fleets to source reliable components from one

specialized supplier.

Die Bedeutung der richtigen Auswahl des Stützrings

Selecting the correct BOS Homogenisers back-up ring is

critical for maintaining machine reliability. Incorrect

dimensions or unsuitable materials may result in:

• Extrusion von Dichtungen unter Druck
• Leakage and contamination risks
• Beschleunigter Verschleiß der Primärdichtungen
• Druckinstabilität
• Unerwartete Produktionsausfälle

Our technical specialists assist customers in identifying

the correct back-up ring based on homogenizer model,

operating pressure and application conditions.

Wartung und vorbeugender Austausch

Back-up rings are typically replaced during preventive

maintenance or liquid-end overhauls. Scheduled replacement

helps maintain stable operation and minimizes the risk of

unexpected failures.
