Kaixin Pumps

It would be advantageous to them to send u one to review. It seems ur endorsement on this pump is highly appreciated both here and in the aussie forum! Was about to order the new model until i read the above negative review.

The acid test is to see what wolfy says. If he didn't have any trouble pumping though a plate chiller with the original pump..........

I've not measured the exact flow of the 'original' pump through my HERMS coil or plate chiller, but I've also not noticed any significant/visible drop in performance when pumping through them either.

I'll be very interested to hear if other's have similar problems pumping through pressure, because I was just about to buy one of the high-temp ones myself ... might have to wait a bit.

they are great from transferring a to b but the just don't cope well with pressure as wolfy puts it - my HERMs in this case which is max 2.5m of 10mm tube

Not to hijack the thread but bought two of these and now have one spare due to the reason mention above pm if of interest

Got mine at work today. Got UPS to hold on to it whilst I was away visitng family in Wales.

I went through the charges with a guy at UPS and they are "correct" the £10 VAT is because the VAT is applied to the item price plus shipping plus £6 or so added by HMRC (20% of the £50 or so). The £11 surcharge is fixed and applied by UPS to all packages, so that may be cheaper with a different courier. It would be interesting if someone else picked DHL and see how that goes.

I love the UPS tracking, my pump went on a lovely little round the world trip. This included coming into the UK and leaving again! (a very abreviated version follows):

Testing later this week. I am not too concerened about the low performance when restriced as I am more concerned about shifting lots of of high temp fluids between my three vessels. Watch this space - I will do a few pics and videos.

I would hesitate to say "endorsement" ... more information and review.

Well im in mixed opinions with mine. No problem recircing boiling wort for 10 minutes and then filling 2 FV buckets. However, it lacks umph. flow rate is fine, steady away. Head height is **** and it left 6 litres of water in the HLT then the same again of wort in the copper. Gonna compare against a solar pump.

Seems like most ppl dislike this pump... Regrets??

haven't even attempted using this pump yet and I regret buying it. haha. I should probably test it first then give it a review.

Updates?

My little brown bugger died, but it looks like I'll be better off getting the 80c model instead. I use an I/C, so i will probably chill it to abt 80c manually with some stirring before using the pump to recirc. For 5gallons, it doesnt take that long to bring it down from 100c to 60-80c, the challenge for me is bringing it down from 40c to pitching temp as my tap water is about 30c, and I have to rely on recirculating iced water to bring it down from 40c to pitching temp.

I just have to change my sanitising method for the pump, as I was aiming recirculating the brown pump from last 15mins of the boil. That probably killed it over time.

I think Barneey would he interested in taking the front from your solar pump off your hands as his just broke.

[darkonnis]

the 80c version might be ok, but I'd stay well clear of the company as a whole myself now that I own one of their products. Thinking back on it i'd probably go for a drill pump myself now or a normal shaft driven one. Considering what I use it for, I can't think of a reason to ever need to throttle back the pump which cant be done via bypass. Also after speaking to a local microbrewer I dont see magnetic drive as important as I once did as he literally dismissed the idea by saying if you use a good pump and clean it properly wheres the issue? I'm inclined now to agree, you pay more for a very small upside.

Seems like I'm better off getting another unit of the brown pump then.

I finally got round to connecting this up today. I couldn't get my 1/2" bsp barb to screw on properly. I suspect not bsp thread. i turnedmiti turned it on and a trickle came out the end. Not tested it properly yet but seemed very weak

[Highlander]

Its not sounds good. Could just be a poorly sized thread.
I can cut 1/2" BSP if you would like me to run a die over it.

Thanks for the offer mate. I'll wait until I build my brew stand and am almost ready with everything else and I may give you a shout if I can't get it sortedr

[darkonnis]

belter, I noticed mine are a bit bigger than 1/2" but with a little elbow grease and some PTFE I get solid seals. Could be worth a try? But yes, they are very weak
