4.1.2 Product presentation

Based on the multi-stages Roots pump technology, theACP 120G, ACG 600G provide
the benefits of clean and dry vacuum for applications in industiral and research
& development.

These pumps are characterised by their robustness, their availability for pumping cycles
on high volume and unrivaled long mainteanance intervals (up to four years in clean ap­plications).

For each model, a "large volume" option is available. In this configuration, a frequency
converter is installed on the FB and on the Roos blower, to allow the pumping of large
chamber volumes > 1 m3 (max. Volume 10 m3).

5.3 Connection to the water circuit

In order to limit corrosion and motor cooling circuit clogging, it is recommended to

use water with the required characteristics (see 12.2.2).

If the ”solid particle size“ and ”solid pollution” water characteristic values cannot be
reached, install a filter on the water input.

The use of uncontrolled city water can lead to water circuit clogging due to lim­escale deposition.

This may necessitate, in the worst case scenario, a complete cleaning and overhaul of
the cooling circuit.

The presence of micro-organisms like aquatic weeds and micro-biological sub­stances like bacteria can lead to cooling problems in the pump.

 An appropriate water treatment system must be used to prevent the growth of such

microorganisms.

8.1 Shutting down for longer periods

Risk of build-up of process residues

All process pumps are designed for continuous operation in pumping process gas and
should not be stopped. Pfeiffer Vacuum will be released from any warranty and liability
claims if a process pump is stopped for a prolonged time leading to condensation of by­products, powder build-up or corrosion inside the pump. The only guaranteed solution
by Pfeiffer Vacuum to restart a process pump after a prolonged stop is to perform a com­plete overhaul of the pump.

Despite this recommendation, if the pump is shut down for a prolonged time, it is advis­able to follow the precautions mentioned below in order to reduce the risks of condensa­tion, powder build-up and corrosion inside the pump.

 From the process chamber, flush the pump using a dry inert gas, such as nitrogen,

through the inlet port during 30 minutes.

 Stop inert gas supply and let the pump running at ultimate pressure for 5 minutes.
 Stop the pump and close inlet port with the appropriate blank-off flange.
 Close the pump exhaust with the appropriate blank-off flange.
