Knifel Submersible Pump 3000L/H 60W Dry Burning Protection with Ultra Quiet Design 3m High Lift for Fountains, Hydroponics, Ponds, Aquariums & More……

Quality pump . There are some things to watch out for. There is very little difference between minimum and maximum flow rate in my opinion. Make sure it’s not to powerful or not powerful enough . Other than that it’s a quality pump with cut out for overheating. Essential since I burnt out a cheaper model that hadn’t that feature.Also different size fittings for different size pipes. Overall highly recommend.

Easy to install. The pump tends to lose power after a few hours this is stated in the product specification. I use the pump for use of a pond " run off ". My advice is when you notice a drop in the pump pressure turn off for a couple of hours to " cool off " Then restart. Apart from this I think it a is great value pump and would recommend it for a small medium sized pond.

Great little pump with good volume of water flow. Only drawback is that the water inlet can get blocked by leaves etc so needs cleaning every few days.

This pump was necessary when our main pond pump was out of action, it supplied sufficient oxygen for our large Koi treating them to a good waterfall effect.

The inlet area is too small. Every 3 to 4 days it needs cleaning out, or the pump inlet gets clogged up. Seems to me like poor design. I have had to put a plastic surround on the pump, so it goes a least a week without stopping.

Used for circulating water in the pond

Replacing an old (working after 18 years) pump previous used for a pond now enclosed water feature. It had 30m soft rubber cord, and a large outer shell that filtered out anything larger than 1mm in all angles. This means even when the bottom/sides of the pump are blocked by soil, the top would allow water to keep the pump going.Now this pump, 2m cord, and intake is probably 5cm^2. Terrible. Likely works in perfect conditions but as my pump is hard to reach (under the feature) I am going to need to make something that filters. Not a good design, find something better.

Works well . The fittings for the hose that screw into the body of the pump can be pulled out by hand ( loose thread) I will use ptfe tape but shouldn't have to .
