Does what it's supposed to do. This is my third mag pump. I've been working my way up throught the years. My first was 250, then a 500. This is a 700 gph.(They all still work fine.) I use it with a their matching 1 sq, foot filter. You must use an add on filter or it will be constantly clogging. The 700 is perfect for the Bell Type Fountain.

I looked it several different pumps to power my aquaponics system. This unit was recommended by the guys at Friendly Aquaponics so I thought I couldn't go wrong. I have about 400 gallons in my system and the goal is to cycle at least that amount every hour. By the specs this pump should be more that enough to handle the job, but it seems a little underpowered to me and next time I think I will go with a larger Danner pump as the pump seems to be very well made. This is not like the cheap Chinese pumps you get off Ebay.

It came with a basket that keeps a lot of the solid material out of the pump, but at the same time it doesn't have any problem pumping the fish waste or algae buildup. I have been running it for 2 and a half months and have not had to clean it out once. It has a standard 3/4 in pvc outlet so I was able to use pvc piping bought at the big box store.

added this pump to the pond with a skimmer filter. Not so impressed. It "says" its 700gpm but the smaller 500 pump I got at homedepot out performed this on by miles.It might make better for a small filter.It should be rated 300-400gpm by its performance

In my opinion, there are none better. I have experienced from three to five years service with Pondmaster pumps running our Koi pond display fountains 24x365.

The failures usually occur where the magnet's spindle interfaces with the front cover: the front cover's cup is usually worn. I have been successful replacing the front cover - IF the supplier has not changed the cover's design.

Cons regarding the Pondmaster is the new flimsy plastic pre-filter (see Danner 02527 Pondmaster 700 gph Pump), which easily collapses under debris accumulation. Save your old heavy plastic spline strainers, which (with a hose covering) do not collapse. Whomever engineered the new pre-filter missed BIG TIME - and that is the opinion of more than one ponderer in Oklahoma.

Put the pump (brand new out of the box) in a refilled/clean pond with everything perfectly clean. Worked for about an hour before it started stuttering. Sounded like air or something was caught in the impeller, but its perfectly clean, the pump is submerged completely. Pulled off the impeller to see if anything was caught, but it was perfectly clean. The Danner Mfg website is of no help. Also for the 1 hour or so it did work, the output was much less than expected (barely more than my 300gph we were replacing). All in all I'm quite disappointed.

Purchased a Pondmaster Pump 9.5 as a replacement pump for my Koi pond. Their product is very cheaply made and does not last much longer than their warranty. Shortly after being in use for a little more than a year, the shaft in the impeller broke due to being made of plastic. This is the first impeller I have seen using plastic! This product is not recommended! Replacement parts are available but the cost does not warrant replacing. What will you receive? More plastic!

Good durable pump. Works well if you have a sufficiently large filter so that you dont have to clean the filter frequently.

I use mine in an unconventional way. I submerge it in a -30C windshield washing/anti-freeze mixture to pump the solution through computer components. I imagine the plastic will start to crack at those temps, but so far it's held up good for about a year with on and off use.

Order was promptly delivered and has been functioning flawlessly since. I have a rock water feature with apx 40 gal of recycling water and the pump works better than the original. I would purchase again should the need arise

I've been purchasing pumps for my pond for many years until I found this one! It was a hassle to constantly readjust pump settings with every new pump I had purchased as these pumps don't last forever and manufactures don't use the same inlet diameters or tubes. But now the ONLY thing I've had to replace is the impeller which is why pumps end up failing in the first place, and other pumps you cannot replace this part alone. So I've purchased a few spare impellers,and they are very easy and cheaper to replace. I keep the same pump setting and I've only had to replace the impeller once thus far in the 2 years I've had this pump. And I think it was my fault. I could've extended the life of it had I kept the filters clean.
I've read some reviews that the prefilter melts, deforms or looses it's shape. Yes, it does! But this does not justify lowering the rating of this pump. Mine lost its shape, but functions just fine. Who cares! It's under water!!
The key issue you need to keep in mind is that this pump might be a bit more expensive, BUT you can replace parts!! I've done my math and I can asure you that you end up saving money and time in the long run.
If you have had a pond for many years like I have, you know that somehow these pumps break down at the most inconvenient time. Then you can't find the same pump because manufactures change models constantly. Then the pump doesn't fit right, you now need a different diameter tubing, or the GPH somehow is not the same... forget it! Buy this one... and don't forget to always keep an Impeller replacement handy!!
