I use this in my beer brewing process. It is a more economical way to transfer hot liquids than the traditional March pumps used in home brewing. Like any pump, you have to be careful not to introduce air on the suction side or it cavitates and shuts off. The magnetic drive on the pump allows me to reduce the flow without cavitation and all the materials are food grade plastic. I own 2 of these pumps and have been using them for several weeks now. Time will tell how durable they are.

I power the pumps with old laptop transformers rated for 15 VDC at 3 amps. I can draw down 8-9 gallons in under 5 min if necessary. Shipping was super fast and the pump arrived as described. I highly recommend this pump if you are looking for an economical way to upgrade your brewing process.

Size: NewMaterial Type: 3 GPM / 11.5 LPM - Brass NPT Threads Verified Purchase
I use this pump as my primary transfer pump in a HERMS beer brewing system. It is very powerful for such a small 12VDC pump, and is also very quiet. I often have to check to see if it has stalled during extended periods of use because I cannot hear it from the other room. This pump performs every bit as well as the $200 magnetic pumps most brewers favor, but it is a fraction of the price, it is smaller and it uses low-voltage DC power, which is marginally safer for DIY pumping applications than 120VAC mains power.

Pros:
- Powerful: 3GPM is great for a 12VDC pump, and it will build a surprising amount of pressure as well.
- Quiet: When properly primed and mounted, it is nearly silent.
- High Quality: this is made from high strength thermoplastic and feels very sturdy. Fittings are brass, which is a nice bonus at this price point, and makes it simply to swap parts in your system without dealing with barbs and clamps.
- 12VDC power: You are extremely unlikely to electrocute yourself while using or servicing this pump.
- Easy to start: 1/2" inlet/outlet means the pump fills and primes easily via siphoning.
- Easy to service: 4 screws, one seal and one moving part inside the head. Magnetic drive pumps occasionally get knocked out of phase, and it takes about 5 minutes to re-seat this one.
- Features: Auto-protection for dry operation, and overheating. Features not found on more expensive pumps.

Cons:
- Are the brass connections lead free? I hope so.
- This pump does not deal with air bubbles very well at all, and will sometimes stall if there are any stray bubbles inside your system. It can be difficult to re-prime it if this happens.
- Mounting - this is where I took off a star.

Size: NewMaterial Type: 2.6 GPM / 10 LPM - Brass BSP Threads Verified Purchase
This tiny pump works very well, very quiet almost noiseless, so quiet that sometimes I have to touch the pump to feel vibration just to be sure that it is working.
But I must say Kudos to US Solar Pump, the supplier I choose. I mistakenly ordered the BSP threaded pump, US Solar Pump sent me an email via Amazon and inform me of my possible mistake of if I was going to use the pump in the US or in another country, if it would be used in the US then I'd be needing the NPT threads, I corrected that mistake from BSP to NPT via email to US Solar Pumps through Amazon and the correct threaded pump was delivered within 48 hours.
That is what I call attention to detail when it comes to customer service. Kudos especially to the individual at US Solar Pump who was smart enough and very observant and not just ship out just because of what was ordered.

I used this pump with a solar panel in an aquaponics project with my students. It does a great job lifting the water from a tank to the grow beds. I suggest adding the filter which will keep the pump working flawlessly.

This little pump has a lot of oomph. I'm using it as a part of my custom watercooling loop in my computer. Three gallons per minute certainly is something!

Size: NewMaterial Type: 3 GPM / 11.5 LPM - Brass NPT Threads Verified Purchase
This little pump is working great! I'm using it to cycle water through a solar collector and back to a storage tank.
This pump is not self priming so make sure that it's lower than the tank or a sealed system so air doesn't break the prime.

I'm also impressed with how little energy it takes to run. I have two 15 watt solar panels from Harbor Freight driving the pump and the pump runs strong all day. The benefit to using solar besides the obvious free power is that the pump turns off when the sun goes down and on again when the sun comes up synchronizing to the sun when you need it for the collector. The pump starts up easily against any stagnate water pressure in the pipes.
My hope now is that it lasts a long time.

Size: NewMaterial Type: 3 GPM / 11.5 LPM - Brass NPT Threads Verified Purchase
Bought one of these about a 2 years ago and immediately started using it for my home-brew (beer) pump... that means it pumps cold water, hot water (150F) and boiling water (200F+), as well as hot/cold wort (acidic). It worked fine for 1-2 brews then stopped pumping... I contacted tech support and they had me return it for a prompt replacement! They were VERY courteous and actually seemed concerned about what happened to cause the failure (they care about product quality/improvement)!! The next pump has worked flawlessly for over 2 years now and I will be buying another for a secondary pump.
