Durst RCP 20 - Liquid pump question

[Jessestr]

Hi all

I've bought a RCP 20 today in pretty good condition, however it had a few leaks and we seem to have fixed that already. I want to use it for b/w printing.

We discoupled the pump system because that was leaking and we were wondering if its ok if the pump sucks air instead of liquid?
The temperature unit is still in place but won't be used. I'm planning to remove all the parts for color development so it's just a feeder for paper trough the chemicals.

Thanks in advance

Having tried it the whole night, it doesn't seem to affect performance.
Removing the circulation pump without discoupling it from the motor works.
