Maintenance and repair

In order to comply with laws (occupational, health and

safety regulations, safety at work law and regulations for

environmental protection) vacuum pumps, components

and measuring instruments can only be returned when

certain procedures (see section “Notes on return to the

factory”, pg. 122) are followed.

Take advantage of our service seminars, which put special

focus on the maintenance and repair of vacuum pumps.

In normal use, the lifetime of the diaphragms and valves is

parts of the pump are disassembled.


Switch off the pump. Disconnect the electrical

power cord and wait two minutes before starting

maintenance to allow the capacitors to discharge.

chemicals, which have been pumped during operation.
