That looks like a much better pump. The MCP300 I believe may have lacked in reliability/durability.

But I'm not convinced that the did the electrical work required to prevents spikes and power reversals from hitting the PSU, like we did for the Johnson pump. Buyer beware!

Also, with a dead head (TDH?) of 2.2 meters, it's definitely comparable to an Eheim 1250's 2.0 meters, but what's the flow rate?

Definitely impressive specs for the pump.

A brushless motor won't produce the spikes that the Johnson pump does.

I like all of this stuff. No mention of a new radiator though (still going with the BI micro in their kits?) I need to bug Bill for a full kit to play with I guess :)

readers beware !
Ben is posting his FOOLish thoughts and speculations

if you have a question -> ask it
do you now see how stupid that statement was ?
more reading, less posting Ben

lots of info on the pump here

Direct link to OCAU thread (complete with some performance figures from Bill/Swiftech):

If the pump has a brushless motor then there is no need to worry about voltage spikes. That is a nice pump and can’t help but wonder where is it that they are getting it from.

Good looking pump. If the price is right and my block benifits, I would like to test one out.
BigBen2k, I think its perfectly understandable and acceptable to be skeptical. Ignorance of a product that is not for sale and openly analyzed is understandable. Foolishness is when your are faced with facts and ignore the truth. I don't think that word applies.

Good question: Are these custom made or repackaged and resold?

As i only have a hotmail e-mail a/c i can't register for ocau and hence view the posts there.
Could someone please post the performance of this pump here.
As it only uses 7 watts and has a max head of 2.2Meters which seems very good. Thats half the wattage of my maxijet with an extra .7 meters head .
It also seems nice and compact which is another bonus for me.

Bill:

Feel free to threaten me with lawsuits if dissatisfied with the following:

here is the 1/2" data

note the shortfall of the 2 Eheim pumps
reality hurts

Thats for the info men.

Bill did you generate that P-Q curve yourself? If so, what is the method you use to do so? I should give that a go with the pumps I have around the casa.

no, that is from the mfgrs data
I have verified it at 2 flow rates by summing the flow resistances of the system components to predict the flow rate and it seems accurate (±5% ?)
- but really accurate values are needed for each item

next time I have it on I'll measure the deadhead pressure (the easy part)

what you need is to generate a head loss curve for your flow meter,
then put that as directly as possible on the pump discharge after your throttling valve - set horizontally
now read the pressure across the pump inlet and outlet and correct for your meter
hmm, I think you'll need the pressure drop across the valve also

so the swiftech pumps are not custom made, but a resold pump w/ swiftys name and color scheme. Its not a custom change, or the mfgrs data wouldnt apply. The million dollar question.. whos is it? Did swifty also add the foam to the bottom of it? (that is foam on the bottom isnt it?)

I only wish they would offer a chipset tec block. That would be neat.

Bill. how does it compare, noise wise, to the eheim 1250? That is the only pump I have heard, or not heard ever since I mounted it suspended from rubber bicycle tube.

in a couple of weeks or so (??), ck new product announcements
Eheim is better for no noise, but lower pressure/flow capability

Nice, that was the only thing holding me back from running all three blocks tec. Thanks, I will wait.

BrianW

Can this pump run inline?
--> "Anyway iwakis are still better right?"

EDIT: Stupid question. Ignore it.

Better is way too broad. You need to know what you need or require to know what is better for you.

BrianW

Nice to have you drop in Bill.

Some nice looking blocks there. The lower to the base cap for higher velocity in the blocks is real nice along with the large barbs to allow the least head loss.

Is the base's cooling surface the same diamond pattern as that used in the 5000?

And are you free to post further charts and figures on the performance curve & C/W?

Again, great to see you stop in!

same baseplate, changed top
- do you not recall the question you asked back in that old thread ?

the 3 relevant graphs are on the Swistech site under MCW5002
but the only things I will post are new product graphs once they have been announced

LOTS to come in the weeks ahead

Any hope for an AMD tec variant?
