I looked at AMT's website but could not find info about the pumps (maybe I did not look hard enough?),. The Olympus has specific fuel consumption around 720-730 cc/minute - I would assume the pump can flow more than that.

Edit: ok, I see the Titan now, it runs about 1200cc/minute. I'll inquire about the pump for it.

The Ullermen pump runs EU $113, about $160 CDN dollars, versus a locally available 700cc/minute pump @ $117 USD which is $150 CDN dollars - so for 10 bucks more I get an expensive German pump.
