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.
They 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.
