Agilent 6430 QQQ Edwards rough pump oil leaking

Hi Nadim,

Yes you can upgrade to a MS40 rough pump. The MS40 draws more current than the EM28 pumps so cannot be powered directly. The system will need a pump expander box to be fitted as part of the upgrade so the rough pump can be switched on and off by the MS. This is an officially supported upgrade and your local customer care team will understand the upgrade should be able to assist with this.

Hi Ross,

Thanks for your reply.

Ok I understand. Can I still order EM28 rough pump. Is it available for Oder because it is old pump. 

You should be able to but best to get customer care in your region to confirm they can advise on both options. The MS40 upgrade is the better option if you can go for it.
