BEST-IN-CLASS

VIBRATION ABSORBERS

Belman has developed a series of Vibration Absorbers, which are designed for versatile usage in any system where pump vibrations occur. The standard range is made from multi-ply bellows with several very thin layers of stainless steel. This delivers maximum performance regarding: pressure and temperature bearing capacity, noise and vibration absorption and overall cyclic service life.

The Vibration Absorbers have a standard overall length of 130 mm for the easy replacement of any Rubber Expansion Joint. The range of Vibration Absorbers can resolve any problems related to mechanical vibration and have a higher pressure and temperature capacity than rubber bellows. Unlike Rubber Expansion Joints, stainless steel bellows do not suffer from atmospheric damage when used in an outdoor installation.

TECHNICAL DESCRIPTION

APPLICATIONS
  • In pipe systems and installations where vibrations and stresses occur
  • Pumps, compressors, engines, burners etc.
  • House installations, industrial installations etc.
  • Heating, climate, ventilation and heat recovery installations
  • Gas, water and sewage treatment plants
CONSTRUCTION AND DESIGN

The Vibration Absorbers feature rubber bushes for the tie rods for maximum noise and vibration reduction. The Vibration Absorbers can withstand high pressure at elevated temperatures, with flat steel springs holding the tie rods. The tie rods ensure that pressure thrust forces from the pump are not transferred to the adjacent pipe system.

  • Compensate for installation misalignments between pipe systems and pumps, and
    thermal growth
  • Eliminates pressure thrust forces and torques on pumps and other equipment
  • Reduces vibrations, oscillations, and noise (sound and vibration) from pumps into pipe systems
  • The multi-ply bellow ensures maximum performance regarding pressure, temperature and service life
  • Standard design is: 16 BarG, and overall length of 130 mm for easy replacement of rubber bellows
  • Special designs are available to any specification

ADVANTAGES

Vibration Absorbers represents several advantages for the piping designers.

Advantages

What are the advantages of using
Vibration Absorbers?

  • Unlike Rubber Expansion Joints, the vibration absorbers are resistant against
    ageing, high temperatures and UV-radiation
  • Reduction of long-term operation and maintenance costs
  • Increased reliability and prolongation of the service life of the pipe system and
    connected equipment
  • Tie rods as standard for minimum fixation of pipe system (available without tie rods, on request)
