Knifel Submersible Water Pump 1056GPH Pond Pump for Fountains

I built this water garden/ gold fish pond in 2002. I have tried every brand from Laguna to Oasis and many more, Up until now Oasis was my go to brand but that has changed. Since this is a water garden it receives lots of vegetation trash in the pond. The surface area of the impeller cover is very large and will last for days before I even see a flow decrease. Easy to remove and clean good for another solid week at top performance. No other pump I have used performed like this. The price of under 50 bucks to the house I’ll change it out every year for that price but I have faith and easy three year pump with my pass experiences with other brands. For me this is the pump I have been hoping to find. I bought another one as a back up 4-29-24 the thing is a tank. I ran it dry twice and still performing well it looks like you can pull apart to get to the impeller to clean it. They will start to slow down with little fiber wrapping around impeller. I’m almost at a year and still functional. I think it has slowed down a little bit but not bad. I would like to see the back cap and front cap not as flimsy with a stiffer plastic. The impeller house was turned counterclockwise and came off very easy. The cap was removed and a very small metal shaft the the magnetic impeller spins on came out the had a neoprene nipple on the shaft. I was hoping to find fibrous vegetation around the impeller because I have noticed a slight slow down. The shaft had some burrs on it and I sanded it smooth. Other than that removed brown alagea residue and I Had waterproof silicone grease coated the metal rod and notice wear on the retaining cap that I removed so I coated that also. Reassembled the pump very easy no real tools required. I should of put the pump in a bucket to get any oil residue that spins off the shaft it wasn’t a lot but I will alway pre run before placing back in pond from now on. Did a water change just to be safe. My slow down was Debris build up inside the tubing. Pump was quit. I can see the shaft metal rod wearing out and it should of been made stainless steel. When this pump fails it will be due the severe wear on the shaft or the impeller fins break off the impeller. Update two years later and this pump is still running strong.

This pump seems like the real deal. I had another one that stopped sporadically. The pressure coming out of this one is far superior - so hopefully it keeps on going.

The pump itself works great and is able to give a strong pulse thru a 40 inch vertical pipe but the filter pad works poorly. It’s made of a course material that’s intended to trap particles while allowing water thru. Instead, it clogs with debris and limits fluid flow.

Works great, very pleased. Bought the little box net to help it from plugging with leaves.

These work great for keeping little fish and snails out of my filter , and my pond stays glean

unfortunately ponic pumps by ZAHGO are no longer available anywhere so I tried this one. the threaded hose adapter snapped off at the base within minutes of connecting a hose to it. The adapters are super thin and require very gentle care when handling. The problem is, this is where you need it to be sturdy as you are lowering and lifting the pump by the hose/chord. Secondly the published volume was not achieved. This pump replaced a 800GPH ZAHGO pump and it performed at an estimated 70% efficiency of the pump it replaced in identical configuration. Thirdly the cord is 6' long. What the heck. I had to use a short extension chord. Its like no thought went into the design of this pump with respect to durability and practicality. Another disappointment is the profile of the pump is much larger then than the better performing ZAHGO. The included photo illustrates the contrast in thickness of the adapter walls. The adapter on the left is a ZAHGO adapter (thick and sturdy), the one on the right is from the pump being reviewed (thin, frail and broken). Judge for yourselves. FYI: I purchased a NFESOLAR 1200 pump and the hose adapter is sturdy and the cord is 11'. Not sure how it performs yet but just based on those 2 points, I would recommend trying the NFESOLAR line of pumps as opposed to the Knifel line.

Nice compact fountain pump with a lot of splash.

My 4 year old pump has low flow since it ran dry for several hours . I see new version says housing is removable to clean and oil inside - I can't see how to remove it on my old version. before that, pump was fine, good flow and pressure (6' line,less than 3' rise. could have been quieter though

This 880 GPH submersible water pump works very well and has good water flow. It was easy to set up and is powerful enough for what I needed it for. It runs smoothly and has been reliable so far. Overall, a good pump for the price.

it comes with three nozzles, I used the 3/4" and the pump barely moves water to my top pond which is about a Meter (39") up from the bottom pond. Not nearly as powerful as I imagined, the description also doesn't tell you the pump speed cannot be adjusted, like many others. I am going to use the other smaller nozzles to see if that is why it won't lift up to my top pond, as it should. I will update in a day or two to let anyone interested - know. I am going to purchase a more powerful pump that you can adjust, so I can get my waterfall running again after my old pump stopped working. Decent pump but definitely not one to use to lift water

I haven't installed the Knifel Submersible Pump 880GPH yet, but this kind of misleading listing makes me nuts. I bought it specifically because it says "we have added a temperature control protection switch inside the pump" in "About this item". I've already run through 3 cheaper pumps that all burned out because the water level in my pond fell below the pump (I'm blaming the racoons... longer story). Anyway, I receive the pump and in the instructions I read: "Don't have the automatic shut-off. But it has 360 hours anti-dry burning, won't burn out." That's not the same thing! Presumably, after 15 days, the pump will burn out. If I go away for two weeks and the racoons do their thing, I'm likely out another pump. I wanted an auto shut-off switch. Argh!
