SWIFTTECH's "new" pump :"MCP650"

[iakovl]

I just read that swifttech came up with new pump, so i went to the site and then i started to think , were did i saw that pump, and then it hit me , it's the same 12V pump that DD sells, and it's cheaper in DD.
LOL

SWIFTTECH's MCP650
DD's pump

its so funny

[opteron_bitch]

They really the same? They discontinued the mcp600 for this.

yup, better pump reliability

[firtol88]

How do they compare on sound levels?

[BalefireX]

According to Swiftech:
MCP600 is 31~34dBA in a quiet room at 1 ft
MCP650 is 33~34dBA in a quiet room at 2 ft

not directly comparable numbers, but shouldnt be a huge difference in noise levels, for a reasonable increase in performance.

Looks like im not going to have to choose between the mcp600 and teh dangerden pump anymore for when i start watercooling :P

well the AquaXtreme 50Z-DC12 = the mcp600, so that side of the choice still exists.....

better pump reliability

Also a wider voltage operational range from an enthusiast perspective.

The Laing D4's (MCP650) are suitable for under-volting, and makes for a very efficient flow/power pump at lower voltages. Great for the low power/low flow enthusiasts.

At stock voltage they are pretty much equivalent to a 60Hz Iwaki MD-15R, which makes them a very desirable pump.

At higher voltages, although that will likely be voiding one's warranty, they can compete quite comfortably even with mid-range Iwaki's, and yet be dumping less heat into the loop and drawing less power. This makes them great for the balls-out enthusiasts at the other end of the scale.

The noise-level was always my problem with the original whining pumps, so it's great to see the ~10dBA drop or so (based on Laing's original figures), although I'm very curious to know how much noise these new ones make at 16-18v or so...

Bill, not that this is that important to Swiftech, but has there been any discussions with Laing about producing a higher RPM (higher pressure) version at 12v? Say spinning at ~33% faster than the MCP650 does (or by estimates ~25% faster than the original D4's did)?

not (ever) free to talk about new product development
Swiftech is engaged in active research in every aspect of WCing, and this is increasing
can't say more

I'm still wondering what the MTBF is for the MCP600/AX 50Z. It has better performance at greater than 6.5ft of head, uses less energy, and is quieter. Given those attributes and assuming the MTBF isn't crap the MCP600 doesn't seem to have been eclipsed by its replacement.

How so? Isn't essentially all 'pump heat' from an inline pump a function of flow and pressure. So if you have two pumps putting out x pressure at y flow won't their 'pump heat' be the same?

I do agree that they are much less power hungry than a like pump that is AC powered.

Motor heat. Impeller inefficiencies.

Most of these small pumps are ~5-30% efficient in terms of converting the electrical energy into liquid pumping energy - which in turn gets converted into frictional heat.

What about the rest?

[blitz1911]

how much more powerful is this compared to the mcp600 though?

wasnt the original d4 pump and the current DD muffled pump somewhat more powerful than the mcp650?

I put a p-q graph in the pumps thread. It has the older D4 with the data from DD's site and the MCP650 with data provided by Swiftech.

I have a MCP 600. Hands down one of the better pumps I have ever had. It does the job with my water chiller setup. I have an insane amount of 3/8" tubing. There is probably almost 10' of it. I originally set up my system to take to a LAN and wanted to keep the chiller on the floor. I know I should probably shorten it up but I have been a little busy lately. Despite the tube length, it still gets the job done and makes no noise what so ever. It's been running more or less none stop for about 3 months. (Excluding the occasional re-boot).
