Hello,

Does anyone know more details (function and appearance) about the tandem pump in an AWX machine?

Greetings.

Hello,

The tandem pump serves two purposes: on the one hand, it creates the vacuum; on the other hand, it acts as a feed pump for the positive displacement elements.

First of all, thank you very much for the answers.
But @diesel.gustav, what is SSP 209?

SSP stands for Self-Study Program.
These are technical information documents (sometimes also technical promotional materials

).

Best regards, Rudi.

Hello Gustav,

'@Rudi: The self-study programs from Volkswagen and Audi explain the technology in a reasonably understandable way and with colorful pictures. As far as I know, I wouldn't consider them to be blatant advertising.'

Okay, maybe I was a little irreverent. But if you look at, for example, the article about the Touran in '306,' it has certain similarities to those glossy brochures in some aspects.

The older editions were often significantly more comprehensive in certain respects.

Best regards, Rudi.

Once again, thank you for the tips.
I'll take care of it now.

Greetings.
