Replacement pump for Calcium Reactor?

[JCOLE]

The pump on my calcium reactor is working normally but I would like to find a backup pump incase this one fails. It is a Reef Dynamics 125E Calcium Reactor utilizing an Eheim pump. Reef Dynamics is no longer in business so I am worried about finding a backup pump. Does anyone know what kind of pump would replace the Eheim? I cannot seem to find the replacement online.

It looks like it has a round flow adjustment knob on the side, right? If so, my guess is that it’s the now discontinued Eheim compact plus series pump... most likely the Eheim compact plus 2000. They are still available on eBay.
