This lasting, submersible unit is specifically designed to run continuously in fresh water, and has no seals or oil for consistent and safe operation. The unique, wet rotor motor uses significantly less energy than a direct drive counterpart, and the 3300 gph capacity of this pump is great for medium sized waterfalls. A screened base helps keep debris out of the 1.5" inlet, and three legs here elevate the item slightly off the base of your skimmer or pond. Attach a 1.5" MNPT fitting to the threaded outlet for a direct line from the pump to your water feature, or use the included elbow for versatility in situating your tubing. The thermoplastic chassis remains durable for many seasons of use, while the small footprint is simple to place in a variety of skimmers or water features. Power a biofilter, stream, or other aquatic accent using this Magnetic Drive Waterfall Pump.
