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:

Preventing extrusion of elastomer seals under high pressure
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 des homogénéisateurs de la série MG de BOS

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:

Plunger sealing assemblies
Liquid end cylinder blocks
Hydraulic actuation systems
High-pressure valve housings
Systèmes de régulation de pression

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

High-pressure homogenization subjects internal components

to continuous stress and rapid pressure fluctuations. Back-up

rings must withstand:

Pressions de fonctionnement extrêmes
Thermal expansion and contraction
Mechanical vibration
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.

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.
