Description
- DC 12V circulating water pump, load current 1.4A, Max flow rate 10LPM (2.64GPM), Max head 4M (13.1FT)
- Circulating water temperature range -4 ℉~212 ℉, low noise ≤ 30DB, waterproof IP68, service life ≥ 40000H
- The inlet and outlet interface is 1/2 “external thread, with stable continuous output performance and can work continuously for a long time.
- The accessories include a customized DC power adapter (no current sound), brass coupler, hose clamp, and pipeline tape.
- This is a circulating pump, not a self-priming pump, easy to replace and install, suitable for household solar hot water systems, pipeline drinking water circulation, or other circulating pump applications.

I got this because my on demand water heater doesn’t quite get hot enough for my family. I have yet to install it in my water line, but I did run it from a cold bucket of water to an empty bucket and it definitely heated the water. I have a dc pump so hopefully once it’s installed it will solve my hot water issues

I did have an issue with this pump, as after 2 weeks it stopped working. First thing I did was take it apart to try and inspect, hoping that maybe I could catch something before reaching out to the seller. There was a very small amount of sediment that was likely from the line, no the motor. I expected removing the small amount of sediment wouldn’t help, however, I was wrong. The pump seemed to happily do its thing. So, it’s quiet, it does a great job at circulating, it has no trouble with pumping 2m in height (should be good for 4, per seller) and it’s a decent price. After taking it apart, I can also add that it’s well sealed and if installed outdoors, it does seem like it would do very well in the elements. If I run into any issues, I’ll update the review.

I bought this a a recirculation pump for a hot water system on a parts washer ( between a filter and a tankless water heater ) seems to be working fine after about an hour of running! Very pleased so far!

I’m using this pump to circulate antifeeze through ~50 feet of copper tubing in a homemade solar collector connected to a liquid to liquid heat exchanger (water heater) It’s located mid way from the air gap at the top of the collector. This little pump produces some very good flow!
Using the included 12v adapter, it produces greater flow than I needed for continuous circulation, so I employed a PWM controller which is modulated by a microcontroller to keep temperatures balanced.
I’m very pleased that this pump can handle liquids up to 212° F – as I often pump at temperatures in the 160°~195° F range.
In the past week of use, this pump has not leaked at all and runs fairly quietly. Unless the pump achieves cavitation, I can’t hear it running. When primed and running at full voltage, it achieves at least 12′ of lift. Since my application involves about 5′ of lift, the pump is not having to work hard at all!
The inlet and outlet are 1/2″ and the pump comes with two brass fitting to thread onto the input/output – with barbed tubes to fit 3/8″ I.D. tubing. Since I used coupling unions for my pipe, I did not need the fittings but they may come in handy for some installations.
I measured the current drain of the motor at ~1.3 amps at 12 volts DC, so it could be driven by a photovoltaic cell easily.
Overall this is a very good pump for the price point.

I ordered this as a replacement for my solar hot water system. Installation was fairly easy, and performance has been good. The price point was a lot better than other companies I had researched, and so far I haven’t had any issues at all. Quality product, great price, good performance!

This pump/package is a great deal for the price. I don’t plan to use it submerged, but it’s always good for a water pump to resist water.
I tested the water flow with the 3/8″ hose barbs installed and it was almost 2 gallons/minute. The power draw was only 15 watts total to the included AC/DC converter.
The 1/2″ fittings come with o-rings and don’t tighten down well into NPT fittings. Layers of teflon tape could of course combat leakage. Or using BSP non-tapered fittings.
Being able to pump water up to boiling temperature is impressive. The pump is near silent in operation once primed.
I can’t rate as asked the Temperature Control or Suction Power as these aren’t features of this device or its intended application. With the AC converter and fittings provided, this is a great deal and good for low power water circulation or transferring.

small pump that draws 0.2 amps via the 12 volt adapter. Guessing about 12 watts power and plenty of suction power for water. think it will work okay for 50/50 glycol mix in hot water solar system

There is no pressure switch. I should have did more research.
