Cleaning and maintenance

7.3 Vacuum pump maintenance

7.3.1 Maintenance items

Items that require maintenance

Maintenance items

Pump heads, power connection side

Pump heads, vapor condenser side (EK)

Perform maintenance of the pump heads one after the other

In the case of the pump heads, always change the dia

phragms and valves completely, as shown in the image

description for pump head

(1A)

Straightforward maintenance due to split work steps.

On one pump head pair, first replace the diaphragms.

Then change the inlet/outlet valves.

Repeat these steps on the next pump head pair.



Example

Maintenance of the

pump heads

A = 4‑headed

B = 2‑headed
