Maintenance

Ensure that maintenance is done only by suitably trained and supervised technicians. Ensure that the maintenance 
technician is familiar with the safety procedures which relate to the product processed by the vacuum system and 
that the equipment, if necessary, is appropriately decontaminated before starting maintenance. Obey local and 
national safety regulations.

In order to comply with law (occupational, health and safety regulations, safety at work law and regulations for 
environmental protection) vacuum pumps, components and measuring instruments returned to the manufacturer can 
be repaired only when certain procedures (see section Return of Edwards Equipment - Procedure 
(Forms HS 1 and HS 2) are followed.

5.1

Replacing diaphragms and valves

Note:

The images of the pumps may differ slightly, this does not influence replacing the diaphragm and valves.

All bearings are encapsulated and are filled with long-life lubricant, under normal operating conditions these parts 

are maintenance free.

The valves and the diaphragms are wear parts. If the rated ultimate vacuum is no longer achieved, the pump interior, 

the diaphragms and the valves must be cleaned and the diaphragms and valves must be checked for cracks or other 

damage.

Depending on individual cases it may be efficient to check and clean the pump heads on a regular basis. In case of 

normal wear the lifetime of the diaphragms and valves is > 10000 operating hours.

CAUTION

Prevent internal condensation, transfer of liquids or dust. The diaphragm and valves will be damaged, if liquids 

are pumped in significant amount.

If the pump is exposed to corrosive gases or vapour or in case of deposits, maintenance should be carried out 

frequently.

Note:

Regular maintenance will improve the lifetime of the pump and also protect both man and environment.

Drain condensate if applicable, avoid the release of pollutants. Allow sufficient cooling of the pump.

WARNING

Before starting maintenance vent the system, isolate the pump and other components from the 
vacuum system and the electrical supply, drain condensate and allow sufficient cooling of the 
pump.
Before starting maintenance, wait two minutes after isolating the equipment from mains to allow 
the capacitors to discharge.

WARNING

Please read section Replacing diaphragms and valves completely before starting maintenance.

WARNING

Before starting maintenance vent the system, isolate the pump and other components from the 

vacuum system and the electrical supply.
