When shopping for a mag drive pump there are a couple things to remember. The amount of water to be moved and when setting up your pump be very sure to use the same size exit piping. So if the pump has an exit of 1” npt. Use 1” pipe or tubing from your local hardware store, the black water pipe which comes in a coil of 100’.
When attaching the tubing to the pump or hose barb I always use two radiator hose clamps to ensure there are no leaks. Never go smaller on the size of pipe, if any size change always go to the next size up and always try your best to limit elbows, the straighter the better for water flow.
I like the mag drive pump because they are easy to set up, cheap on the electric bill and move a lot of water from a small package. The pre filter is a nice feature that is removable to clean when the water flow has slowed down. I’ve owned an 1800 gph Pond master for 3 years with no problems throw in the pond in spring and pull it out for winter and cleaning the filter once or twice a year is all I did. Below are a few different brands for the 2400 GPH range.
These pumps only have one moving part a ceramic/magnetic impeller magnetically-driven. The pumps are submersible but be sure to plug into a ground fault outlet to protect the fish and yourself in the event of a cord failure by accident or critter. These mag drive pumps are perfect for Fountains & Ponds, Fish Tanks, Waterfalls, Statues, even Sump Pumps.
