C-Systems 12 VDC Pump review... - Page 3

Hotseat · 05-24-2004, 06:34 PM

Hey guys, just got off the phone with a engineer I know at GM, an expert in Al / anodizing.

He says, hardcoat typeIII adnodizing impregnated with Teflon or epoxy primed, and "it will never corrode".

That said, we will just ask for type III from now on, although type II has never given us problems, it may settle some concerns

Hope this helps others out as well.

Interesting. How much extra is the type 3?

So, is it the reason you rise the price of CSP-X2 Package from US69.99 to USD73.99? :shrug:

yea the mounting bracket

Thanks

I get it, having three MB 300SD's in the backyard lets you assemble one whole functioning car! Just kidding! No, really, I know where you're coming from, they really don't make a car, at least a nice car like they used to. I'll take a cherry '66 Vette over a brand new one anyday. You'll hear the difference when you start the motor.

8-Ball · 05-25-2004, 03:47 AM

Sorry for being ignorant, but what the heck is an MB300SD?

Is it a result of being english that I don't know what it is?

BalefireX · 05-25-2004, 04:05 AM

Its a Mercedes-Benz 300SD - 3.0 Litre S Class Diesel - and the things run forever - most of the ones I've seen are well past the quarter million mile mark.

On topic, assuming that everyone is satisfied with the corrosion resistance of Class 3 anodizing, what about just making a polycarb "top" for the pump - leaving the main body aluminium, but having the adjustable part of the housing (on the left here) http://www.c-systems.ca/c_files/adjust1.jpg clear?

8-Ball · 05-25-2004, 05:35 AM

That would look great.

Dan, what do you think?

trit187 · 05-25-2004, 05:43 AM

could sell them as acessories, want to keep the price down.

Hotseat · 05-25-2004, 07:40 AM

Everyone that ordered X2 package, wanted a 3 to 4 pin adaptor.
Can't blame them, 10W maybe hard on a single fan port.

As such we now include the adaptor in the package, and just added the cost.
Will come back down when we get more adaptors / better price.

Don't worry about the color, when using Type III, as only the pump chamber will be type III. The other parts will be Type II, and in fact some parts will be plastic with the new extrusion cases.

I still think you guys are worrying about nothing

**Note you can still dye type III fine, the color is darker often. I know many think "hardcoat" can only be gold or black.... but that isn't so. As too costs, anodozing in Canada is REAL cheap, so even it if doubles cost, we are talking about cents...guess we will charge 5$ more... J/K

Another review

http://www.modthebox.com/review323_1.shtml

Wow a 120 gph pump give same CPU temps as a 1300 gph unit, go figure

Just wanted you guys to notice something.

The units I sent him, as we had no stock left, where some of our "bench" tests.
They had been running completely underwater for 6-18 weeks, notice the bolts are rusted....but the housing is completely clear !

Now remember, as stated, we use only distilled water / methonal on our units.

Hope this helps,
Dan

trit187 · 05-25-2004, 12:08 PM

i inverted one of the pics, the spot looks like it could be rust or a spot of currosion.. but without seeing it or better pics i won't say that for certain.

edit: the rusty bolts seem like a reason to run the pump inline(thanks deadeye)

1300 gph ?

Aqua Via 1300 = 370 gph

Still looks good though

nicozeg · 05-25-2004, 12:36 PM

I miss the third rpm monitor wire on this pump. if the motors used have the option please include it, is would be a killer feature over all the other pumps in the market.

8-Ball · 05-25-2004, 12:38 PM

I have to agree. RPM monitoring would be GREAT.

Do you not mean the other way around?
It would be better to run it inline !

trit187 · 05-25-2004, 12:43 PM

oops my mistake, meant to say submerged, it's almost 2am, i'm a little tired.

j813 · 05-25-2004, 01:00 PM

Is Dan up to this types of recommendations?

Hope so

LOL, funny guy. I have to commend you on your quick reactions to the suggestions that are being made to you buy this bunch of guys. They are indeed very knowledgeable, some lacking in personality but most very knowledgable. And being an engineer you should have no problem reading and speaking their special language. I am another person who will definately be buying a set of your pumps, I am just going to wait for the new changes to be implimented. Also if you are considering makind the polycarb top I would be a guaranteed sale there also. Best of luck in your endevours.

Hotseat · 05-26-2004, 07:41 AM

You can run them underwater....but not designed for, and therefore not suggested.

We can change case for this purpose, given an OEM order.

We test underwater, because we have a test tank we have been using for years.
The pumps often run months, during testing, hence is easier just to run them all underwater in a big tank.

We do these tests whenever we change supplier / materials / case design, etc.

Must be all those years at Boeing, got to test everything just to be sure

Never a bad thing in my book.

SysCrusher · 05-28-2004, 06:27 PM

Hotseat? I have a suggestion. Make the inlet bigger with maybe a 1/2npt thread. Less restriction on the inlet would be better? I would pay extra just for that. Soon as I can get one I'm going to give two of them a try.

8-Ball · 05-29-2004, 04:59 AM

I would imagine that the size of the opening above the impeller has a bearing on how efficiently the impeller works.

Much like for radial fans, there is a RECOMMENDED opening size above the impeller.

I guess the question would be - What is that recommended size?
