The Pondmaster Pond-Mag (Mag-Drive) is Danner's pond-branded magnetic-drive pump — the workhorse circulating pump with one moving part, a ceramic-shafted magnetic impeller. No seals to wear out, no oil to leak.
Oil-free and fish-safe. The power unit is epoxy-encased, so nothing can contaminate the water — which is why mag-drive is the default choice around livestock. Runs submerged or inline, in fresh or saltwater, indoors or out. Backed by Danner's 5-year limited warranty.
Pick your size
Match the pump to the flow you need at your head height — the vertical distance from pump to highest outlet. Flow falls as head rises, so buy from the max-head column, not just the GPH in the name.
| Flow | Max head | Watts | Outlet |
|---|---|---|---|
| 250 GPH | 7' | 24 W | 1/2" |
| 350 GPH | 10.5' | 35 W | 1/2" |
| 500 GPH | 10.5' | 45 W | 1/2" |
| 700 GPH | 11.5' | 70 W | 1/2" |
| 950 GPH | 13.5' | 93 W | 3/4" |
| 1,200 GPH | 13.5' | 110 W | 3/4" |
| 1,800 GPH | 16.5' | 145 W | 3/4" |
| 2,400 GPH | 17' | 237 W | 1" |
18-foot power cord on this Pond-Mag line — long enough to reach from the middle of most ponds to an outlet without an extension.
What people use them for
- Ponds, fountains and waterfalls
- Fish tanks and quarantine systems
- Statuary and spitters
- Utility and sump duty — moving water out of a flooded room included
Pond-Mag or Hydro-Mag?
We also carry the Supreme Hydro-Mag — the same Danner pump platform in different trim. The practical differences: this Pond-Mag has the 18-ft cord; the Hydro-Mag has a 10-ft cord plus an adjustable venturi aerator on most sizes. Pump sitting out in the pond? The cord decides it. Quarantine tub or reservoir that wants extra aeration? The venturi decides it the other way.
Why buy from ChampKoi?
ChampKoi has run ponds and quarantine systems from our San Jose, California facility since 1998. Tell us your head height and tubing size and we'll size the pump properly — the most common pump mistake we see is buying the GPH number and ignoring the head curve.
