5 Vibration isolator
5.1 Description
A Vibration Isolator can be fitted to the inlet-flange of your EXT pump to reduce the transmission of the small amount
of vibration generated by the pump to your vacuum system.
The Vibration Isolator has two flanges separated by a flexible stainless steel bellows and an outer rubber anti-
vibration collar.
The Vibration Isolator is designed for use with a vertically mounted pump only.
5.2 Technical data
Table 4 - Vibration isolators technical data
Minimum attenuation of vibration amplitude
*
*
Vibration attenuation depends on frequency of interest and mass of vacuum system. Stated value is typical
for vibration at pump operational frequency, and for system with mass of ~200 kg.
