Not a Laing DDC pump but works like one
343220
To be exact this is not sized like a Laing DDC pump and has a few different features that are mostly good and also a few negative points as well. Overall the pump works well and seems to be almost leakproof due to the heavy amount of resin used around the motor, if you remove the housing you will see what I mean. The pump I got spins up too around 4500rpm and handles a 420mm with a 280mm radiator with 1 Alphacool Eiswolf and 1 Eisbaer block with 16mm petg tubing with no issues. Getting air out took about 2-3 days but it may take less if you use different blocks for cpu and gpu.

I don't really have any real complaints besides  these. 1st the pump is taller than a laing ddc so you cant use most heatsink kits and dampening kits as well, if they make them for this pump I haven't seen them so I may be wrong. Some reservoirs such as the Phanteks r220 where you can mount the pump directly to it the included heatsink won't fit because the screws are to short for it. I didn't have any issues with overheating or the pump running hot so far. 2nd the propeller design is taller than a normal ddc pump so it barely fit into my r220 reservoir without chocking the waterflow or grinding on the reservoir. 3rd the pump noise is noticeable above 2300rpm and will bother you above 3000rpm and when you get to 3500+ it willfrustrate you, for me the sweet spot was around 2500-2700rpm since my pc is 10 inches away from me. I tried using some sound dampening by using the soft side of velcro pads inside the pump housing and it helped somewhat since it soaked some of the vibrations. 4th and most important if you mount this pump to a reservoir directly be extremely careful since there are 2 white plastic orings in the propeller that may fall out and it may throw the propeller off balance or cause a leak so be cautious.

Besides these issues the pump is solid and I would recommend it. The only review for the pump shows that it works similar to the d5 pump with having 900 max lpm vs 1500 for the d5 but having much more pressure with similar noise levels.

It's a very nice floor pump (high quality) and pumps tires up to desired pressure reasonably fast. You have to get use to threading the chuck on to the valve stem, but it does seem a little more secure than the lever chuck attachments.

This pump was purchased to replace a smaller 1/3 HP pump that had developed a funny habit of cycling on and off for about 20 minutes each time it pumped the sump. It never really failed but I didn't want to push my luck. Unlike the plastic pumps from the big box stores, this thing is heavy and built like a tank. Including the check valve it took about 1 to 1.5 hours to install. Not a hard task if you have some basic tools...

Pump arrived on time and in good condition.  I've hooked in up and it is working well.  I like the ability to adjust the flow rate.  Thanks

I was lucky enough to snatch one of these up at a promotional price so I didn't have much to lose.

I have used this pump to air up several high volume mountain and fat bike tires now and am impressed. It works quickly and easily. The pump head works great on presta valves, but I don't have any schraders to try it out on. The pressure gauge is quite accurate so far when compared to my stand alone precision gauge. Quality seems pretty decent for the price point, but time will tell. I will update this review should I experience any failures.

Seems on par with big name brand mod grade pumps I have owned over the years and I wouldn't hesitate to buy another. The one criticism I do have is the base is lightweight plastic and the barrel is heavy. This gives the pump an overall high center of gravity and prone to tip over.

I liked it enough I ordered two of their mini pumps to take along rides.

this pump is good so far but i only used it for couple of days; i collect the laundry water, store it in big barrels then use it to water the grass. i live on an inclined property and it pumps good.

the only pain in the neck was to find a solution on how to convert the fittings that it came with so i can connect it to a water hose. I went to Orchard Supply and then matched the screw on fitting with 1 1/4" PVC fitting then used a reducer with a proper hose connector.
this was not an easy task until i found the solution.

works with the 100 series pumps. rounded surfaces on connectors between the springs help prevent wear

Replaced defective Oem pump and it works like it should.

The boxes all say ACDelco but the pump itself has no ACDelco PN or markings. I was more than a little suspicious but I but I went ahead and installed it and it works. I just hope it lasts. Never use anything in a 6.5L GM TD except an ACDelco if you can keep from it as the 6.5 is very picky about its lift pump.

Great pump at an affordable price.  Used it to drain water out of my pool before closing for the winter.....moves a lot of water in a short period of time.

I bought this to replace my 10 year old pump.  It is supposed to be the same model.  Internal pipe threads on outlet were oversize so fittings bottomed out without sealing.  Made it work by finding an extra long fitting and forcing it to seal against the bottom.  Luckily (and unexpectedly) it did seal.  Pump and motor are both noiser that the original unit, but not by much  Pressure is down a couple of PSI vs original as well.  Motor runs cooler than original.  It is doing the job.

I have used this all summer to run a sprinkler pump. It's only 1 hp, so I haven't really challenged the capacity, but there is no sign of wear and it is working fine. The cord is a heavier than the 10-gauge cord I bought at Home Depot, not sure whether there's more copper or just more insulation. But even as heavy as it is, it coils up fine.

Seems to be a quality pump and easy to use. Time will tell on durability.

I like that it adjust. It was a good price and works fantastic for my application. I homebrew so i use it to run ice water thru a wort chiller in my kitchen sink. Great little pump

Followed another review and bought this to replace the $20+ pump in my Drinkwell Platinum about a year ago. Works perfectly. You don't get the flow control because this pump doesn't have the knob but other than that it fits the same and you clean it the same way. Glad I tried it out, I will buy this pump again when I need one.

I bought this pump to use as an auxiliary garden pump. It handles six sprinkler heads at one time without a strain. When my in-ground system needs a replacement pump I will be ordering another of these pumps. The only draw back that I can see is the mounting holes are too far under the cast iron body to get  the lag bolts in and tightened down. I had to use shorter lag bolts than I wanted to making me think it is not securely mounted to the dock. Time will tell!! The pump arrived in good condition and on the day that Amazon promised. I'm very happy with this purchase.

Wasn't entirely clear from the description, when I ordered the fountain pump, if it was the correct one for the fountain I have.  Turns out it's not, but it's close enough that I'm able to make it work.
