Someone ask for good D5... These two...
Did you hear that guy say Only difference he recognize, on only problematic pump from 5 tested on video is small parts on EK D5 G2 PWM and other 4 models don't have that at all, or don't have exactly same. I couldn't see what is true. Don;t have them at all, or they are different than on only problematic pump?
IF HE FIX PUMP VIBRATION DRILLING RESERVOIR, TOP OR D5 DISTRO THAT'S OBVIOUS CASE FOR AVOIDING. BECAUSE PUMP NEED MORE SPACE AND BECAUSE OF THAT YOUR CASES VIBRATE MORE.
YOU CAN DEFEND PEOPLE WHO MAKE SUCH MISTAKES DURING PRODUCTION AS MUCH YOU WANT, BUT THERE IS A TWO OPTIONS.
1. HARDWARE STORE WHO SELL LAING D5 38/810N FOR 250-300$ AND BUY THEM ARE IDIOTS.
2. LAING D5 38/810N WITH PRICE 250$+ ARE DIFFERENT SOMEHOW THAN PUMPS OFFER IN COMPUTER STORES.
No 3rd option. You can say they have Bronze top, it's Strong version, it's different wattage, yes, all of this true, but among them is and 810N model with absolutely same specification, strength, port size and top as pump sold in computer stores as XSPC, EK, Alphacool, etc with price 250$ and Laing sticker.
There is a two much coincidence, to EK start to offer D5 Rubber Dumper exactly in period when they start to sell PWM pump.
And to tell If pump vibrate more use other soft rubber. Why? We know how much D5 vibrate after 15 years of use.
I can't say is it Lowara with Speed Controller same as 4 other pumps, or is it Watercool WCP D5 wSpeed Controller or Watercool non WCP D5 wSpeed same as other pumps on video clips who didn't cause vibration on normal top. Actually that's not top, that's distro carefully made for D5 impeller and one of pump EK D5 G2 PWM vibrate until he drill more Distro and than pump worked like others.
His conclusions is probably that now heavier impeller spin faster and spin on slightly more distance because these metal parts who make him heavier.
"Which among these did you buy?
And I would like to know answer on that question.
Logic say model with Stainless Steel WCP, but again cheaper variant is older stock and less chance that they change something.
And I would like to know answer that would save me importing from Canada or USA Swiftech MCP655TM wSpeed Controller or Laing D5 Ecocirc from DazMode site.
He say Original Laing D5 rebrended later by EK, and others. Some people say that's like EK Lowara.
My EK-D5 G2 PWM vibrate, He vibrate worse on 55-70% than on 70-100%.
On speed where she need to be used most of time he make worse vibration, than after that vibration become less but pump motor noise is stronger.
And EK when I asked RMA answer to me Don't tight pump in top too much. I didn't tight much, I tight less then default but I could allow water to leak.
Their answer perfectly fit with solution of this guy. They tried to explain me if I don't tight pump to much space between impeller and channel inside will be lower.
Same as guy on video make him bigger with drilling and stop vibration and grinding noise. But you can't tight D5 Ring if rubber and D5 is not pushed properly.
