Kasia, Find out what the model of the controller is. On older Delta units it is a TCP 120 or 121. If that is the controller you can run many pumps off of that. I have run Pfeiffer/Balzers 50,60,63,170,240,260 pumps all for that controller. You can get a rebuilt 60 pump and it will work the same. If that is not the controller find out what it is and you may be able to use other pumps from the same company to give you more options.

Does anyone know where we can buy a new one (of course the old one is not produced anymore, so we will have to make an upgrade)? Our only option for now is MasCom but we would like to know if there is a different possibility. I will be grateful for any tips.
