2. Introducon
This manual provides installaon, operaon and maintenance instrucons for the
Vibraon Isolator which is an accessory for the nEXT pump.
If you use the vibraon isolator with any other item or isolators from dierent supplier,
the eciency of the equipment can not be guaranteed.
2.1 Overview
The Vibraon Isolator is used to reduce the transmission of the small amount of
vibraon generated by the pump to the vacuum system. You can install the Vibraon
Isolator to the inlet ange of the nEXT pump.
It consists of two anges and a damping mass between the anges. The anges and the
mass are separated by special O‑rings and rubber washers which manage the sealing
and also the damping.
The Vibraon isolator is designed for use only with the vercal oriented pumps.
