Laguna Max-Flo 960 Waterfall & Filter Pump is designed to circulate water loaded with moderate amounts of solid particles (or solids) and transport them to suitable external filter systems (including pressurized filters) which then trap debris that could potentially pollute pond water, effectively filtering the pond. Max-Flo is ideal for use with filtration systems and for creating waterfalls and watercourses. Easy to install and operate, the pump is completely submersible and engineered to run continuously. Laguna Max Flo solids handling pumps are powered by a magnetic-driven motor that is unmatched in the market for its ability to generate powerful and continuous water flow while consuming minimal electricity-the perfect combination of high pump efficiency and low energy costs. Easy to install and featuring Click-Fit Fast Couplings with outlet diameters of ¾" 1", 1 ¼", the Max-Flo 960 can handle solids up to 1/4" in size and is good for ponds up to 1920 US Gallons. The pump is manufactured in Italy and guaranteed for 3 years.
