[labnetwork] Looking for a MAG.DRIVE 1000 Turbo Pump Controller for a MAG 900 CT Turbo Pump

Tue Jun 12 15:18:05 EDT 2018

Thanks Brent.  I am talking with a 3rd party vendor to do exactly what you're talking about.  Getting these parts repaired has been a major and very long ordeal.  I am so done with trying to get these non-supported and out dated parts fixed when I have external clients, faculty and students climbing the walls that want to use this tool.  Even if we were lucky enough to get them repaired like last time it is still a ticking time bomb waiting to go off again.

BTW, does anyone have schematics on the controller, too?

Cheers!

Hello Julia,

We had our pump go out in 2014 and decided to replace it with a different manufacturer's pump and controller.  Our STS DRIE is a legacy tool with limited support, so we decided to start upgrades ourselves.

We went with a Edwards STPA1303CV pump and SCU800 controller with associated cables and vent valve.  The total price was a lot less than the STS OEM solution and we were able to get it in days rather than months.  This pump is a 1300L/s rather than the older 900L/s, but we see no difference in processes, the throttle valve takes care of that.  We did have to create a custom interface for the controller to the STS DRIE, but this was because we did not want to cut the cable and just use a plug in replacement.  We used something like this part below for the interface:

https://www.amazon.com/Connector-D-sub-25-pin-Terminal-Breakout/dp/B073RG3GG6<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.amazon.com_Connector-2DD-2Dsub-2D25-2Dpin-2DTerminal-2DBreakout_dp_B073RG3GG6&d=DwMD-g&c=pZJPUDQ3SB9JplYbifm4nt2lEVG5pWx2KikqINpWlZM&r=EhqHy4a2rnA5a4ehzWAAfKveFS3lPv3RmQTaTocONM4&m=AcKQhgy_28FYjnScrbko2ttSkc0ww6nGU5XndfpV2io&s=KJXuNbhVKUC03eqSxTGJF-gUDcRirit1I3I4mg900vY&e=>

The DRIE computer is sending a signal to start the pump and looking for feedback that the pump is at 100% speed.  Our engineer got all this installed and we have been running for the past 4 years without any pump issues.  We may still have the old MAG DRIVE 1000 controller on a shelf, I'll take a look later.  The good news is there is a path forward.

Best Regards,
Brent

Hi Julia,

Sorry to hear about your Leybold Mag Drive turbo controller.  I have been dreading the day our (last) Mag drive 1000 dies.  I acquired one as backup a few years ago but the drive in use died and was not able to be repaired.  So we are down to our last one and its currently in use.

I  have spent some time looking at the control signals and the good news is that I think you can interface a different pump controller.  We were under the impression for a long time that the interface was something special and required a $100k STS retrofit (that included the new turbo and controller).  I've gotten as far as understanding the Leybold interface and making some notes on how I think it operates.  I have been planning on figuring out how to install a replacement controller that can utilize the existing STS interface signals but I haven't started that.

If you get to the place where you just have to put on a different turbo, I would be happy to share what I've generated.

Good luck!

We have an older STS DRIE with a Mag 900 CT turbo pump on our DRIE.  The controller (MAG.DRIVE 1000) for the turbo pump wont power up and has died.  So, I am trying to locate a functioning/refurbished controller.  I know these parts are getting very scarce (PTB Sales dos not have one, even though their website says otherwise) so any help would be appreciated.

Cheers!
