2. Introducon

This manual provides installaon, operaon and maintenance instrucons for the

Vibraon Isolator which is an accessory for the nEXT pump.

If you use the vibraon isolator with any other item or isolators from dierent supplier,

the eciency of the equipment can not be guaranteed.

2.1 Overview

The Vibraon Isolator is used to reduce the transmission of the small amount of

vibraon generated by the pump to the vacuum system. You can install the Vibraon

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 Vibraon isolator is designed for use only with the vercal oriented pumps.
