Expansion joint flanged type ZKB DN100 149B12557C

Vibration isolators – reducing vibrations and noise in installations

The ZKB type flanged vibration isolator is a structural element designed for piping installations, whose main task is to dampen vibrations and compensate for length changes. This reduces the transmission of noise and vibration to the building structure, and also protects the installation itself from damage caused by stress. Made of EPDM rubber and galvanized steel, it combines flexibility and durability.

Construction and application

This model, with a nominal diameter of DN100, is characterized by a flanged connection, which facilitates assembly and disassembly if necessary. The flanges are drilled according to PN10 and PN16 standards, ensuring compatibility with a wide range of piping systems. ZKB isolators are used in water, heating and industrial installations where there is a risk of vibration or the need to compensate for thermal expansion of pipelines. They serve to reduce noise generated by operating equipment (e.g. pumps, fans) and protect the installation from conducting electric currents.

Key features and benefits

• Vibration damping: Reduction of vibration transmission to the building structure and installation components. This translates to quieter system operation and longer component life.
• Movement compensation: Ability to compensate for expansion and contraction of pipelines resulting from temperature changes, preventing stress and damage.
• Noise reduction: Reduction of noise generated by medium flow or equipment operation.
• Durability: Made of high-quality materials – EPDM rubber (or NBR in alternative versions) and galvanized steel – guarantees long-lasting and reliable operation.
• Versatility: Can be used in various types of installations – water, heating, industrial.
• Safety: Protection of the installation against conducting electric currents (depending on the specification).
• Easy installation: The flanged connection facilitates quick and safe assembly and disassembly of the isolator.
• Operating parameters: Maximum operating temperature up to 95°C and nominal pressure 1.6 MPa ensure a wide range of applications.
