Older Tunze pumps

[TampaReefer79]

So I received my last 2 used pumps that I bought last night. The 6200 series pumps that I bought ended up being:

6260.10 and 7240.

I'm just wondering what you can tell me about these pumps. To be honest, I thought I was buying 6201's. What is the flow rate on the pumps that I bought? And on the 6260 it says it's to be used in pulse mode only? Is this accurate and why?

Also, with the 2 pumps came 2 hockey pucks as I see them referred to. One is the large normal one I'd expect to see and one is the itty bitty one. They both fire each pump up, but when either pump is hooked up to the tiny puck the output is greatly reduced. What do I do? What would my flow be with a 6260 or 7240 on a little puck?

Thanks!

6260 is a wavebox pump, all of the older pumps used the same 7240.270 driver. What is the model of the transformer? The transformers came in three models, 7210.202, 7410.602 and 6200.800. If the 6260 pump has a 6200.800, for all practical purposes it is a 6200. A 6260 was a 6200 with a 7410.602 transformer. Since it was meant to be pulsed only and only used an average of about 30W of power it only needed a 60W power supply, however if run continuously it used 60W and needs the bigger 6200.800 power supply which is 80W, the 7410.602 is only 60W and has no margin of safety so of the pump gets jammed and draws a bit more it can fry the transformer.
