Sorry, am having a little trouble understanding the exact meaning of what you said, but I think you're asking if it requires a high pumping pressure, what pump am I using, and what flow rates I see with that pump.
The block is less restrictive than the White Water. I'd put it at around a DTek TC-4 sort of restrictivity from looking at BillA's data on the TC-4. That may sound somewhat surprising, but it's true.
Using an Eheim 1250, I see around 7lpm through the block pictured with 2m of 1/2" ID tubing and a heater-core. I haven't tried hard to nail down exact figures but that's the sort of flow/pressure we're talking about.
