What Is a BOS Homogenisers Plunger Ring?

A plunger ring is part of the sealing assembly in a reciprocating high-pressure

homogenizer. During operation, the plunger moves at high speed and under

extreme pressure. The plunger ring supports the sealing function around the

plunger, contributing to pressure stability and controlled movement within

the cylinder block.

In BOS homogenizers, the plunger ring is engineered to match precise

dimensional tolerances and material specifications. This ensures reliable

operation under demanding industrial conditions.

Applications in BOS MG-Series Homogenizers

BOS Homogenisers manufactures a complete range of MG-series high-pressure

homogenizers. These machines are designed for reliability, easy maintenance

and worldwide spare part availability.

The BOS Homogenisers plunger ring is suitable for use in:

• MG2
• MG3
• MG4
• MG12
• MG14
• MG18
• MG30
• MG45
• MG120
• MG124
• MG140

Each plunger ring is selected to ensure compatibility with the specific

pressure range and capacity of the MG-series model.

Designed for High-Pressure Performance

High-pressure homogenization subjects internal components to constant

mechanical stress and pressure fluctuations. The plunger ring must:

• Maintain sealing integrity
• Support stable homogenisation pressure
• Reduce wear on packings
• Minimize vibration
• Withstand temperature variations

BOS Homogenisers plunger rings are supplied for industrial applications

where reliability and long service intervals are essential.
