Rannie Back-Up Rings for High-Pressure Homogenizers

Rannie back-up rings are critical components in the sealing

systems of APV Rannie high-pressure homogenizers. Designed to support

primary seals and prevent extrusion under extreme pressure, back-up rings

play an essential role in ensuring machine reliability and consistent

homogenisation performance.

BOS Homogenisers is a specialized supplier of spare parts for Rannie,

Gaulin, SPX-APV and BOS homogenizers. With more than 75 years of

experience in homogenisation technology and a global distribution network,

we supply high-quality Rannie back-up rings with fast and reliable delivery worldwide.

What Are Rannie Back-Up Rings?

Back-up rings are auxiliary sealing elements installed together with

O-rings, packings or other primary sealing components. In Rannie

homogenizers, these sealing systems operate under very high pressures

and continuous mechanical stress.

The main functions of Rannie back-up rings include:

Preventing extrusion of elastomer seals under high pressure
Maintaining the geometry of the sealing assembly
Supporting primary seals during pressure cycles
Reducing deformation and wear
Extending overall seal service life

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

prematurely, leading to leakage, production interruptions and

increased maintenance costs.

Applications in APV Rannie Homogenizers

APV Rannie homogenizers are widely used in dairy, beverage,

pharmaceutical, chemical and biotech industries. These machines

are engineered for high capacity and high pressure, requiring

durable and precisely manufactured sealing components.

Rannie back-up rings are typically used in:

Conjuntos de sellado de émbolo
Bloques de cilindros de extremo líquido
Hydraulic valve actuation systems
High-pressure valve housings
Pressure control assemblies

Each back-up ring must match the specific Rannie model and

operating pressure to ensure reliable and safe operation.

Engineered for High-Pressure Conditions

High-pressure homogenization subjects internal components

to continuous stress and rapid pressure fluctuations.

Rannie back-up rings must withstand:

Presiones de funcionamiento extremas
Variaciones de temperatura
Mechanical vibration
Exposure to process fluids
Dynamic movement of adjacent sealing components

Dimensional accuracy and correct material selection are

essential to prevent seal extrusion and maintain consistent

performance throughout the service interval.
