Danner® Pondmaster® Pond-Mag® Magnetic-Drive Water Pump - 1200 GPH

Continuous-Duty Epoxy-Filled Magnetic-Drive Pond Pump, 1200 GPH

The Danner® Pondmaster® Pond-Mag® is a continuous-duty magnetic-drive pump for ponds, garden fountains, and water features. Filled with epoxy instead of oil, it cannot leak oil into pond water if a seal ever fails, and with no shaft seals to wear out it is built for years of reliable, quiet service at 1200 GPH.

This model additionally publishes a 13ft 7in shut-off head at 110 watts, with a 3/4in FPT inlet and 3/4in MPT outlet and a 6.4in L x 4.5in W x 4.6in H footprint — figures the smaller Pond-Mag® models don't list separately. A magnetic impeller assembly with a heavy-duty copper winding, standard NPT threads, and an ABS case with corrosion-proof fasteners round out the build.

Frequently Asked Questions

How is epoxy-fill better than oil-fill?

Oil-filled pump motors can leak oil into pond water if a seal fails, which is harmful to fish and plants. Epoxy-fill removes that risk entirely by replacing the oil reservoir with solid epoxy potting.

Does this model have adjustable flow control?

No — that limitation is specific to the smallest model, the Pond-Mag® 250 (PM250). This pump, like the rest of the Pond-Mag® lineup above 250 GPH, includes built-in adjustable flow control.

Can this pump run continuously?

Yes — the Pond-Mag® is built specifically for continuous-duty operation without overheating or wearing out prematurely. It is designed to stay submerged and running around the clock in a pond or water feature.

What type of fittings does it use?

Standard NPT (National Pipe Thread) fittings, compatible with most pond and irrigation plumbing hardware. That standardization makes it straightforward to connect this pump to existing pond plumbing without extra adapters.

What are this pump's full published specifications?

This model has a 13ft 7in shut-off head, draws 110 watts, and connects via a 3/4in FPT inlet and 3/4in MPT outlet. It measures 6.4in L x 4.5in W x 4.6in H.
