The Laguna Max-Flo 4200 Waterfall & Filter Pump is a highly effective pond water filteringing system.
It is designed to process water loaded with moderate amounts of solid particles (or solids) and transport these suspended solids to suitable external filter systems (including pressurized filters) which then trap any debris that could potentially pollute pond water, effectively filtering the pond. The uniquely-shaped pump cage allows the passage of solids sized up to 3/8 in (9 mm).
As always, the pump motor is unequalled in the pond industry for its ability to generate an astounding amount of water flow reliably and continuously at low energy-efficient costs. This is great news for consumers who are wary of costly hydro bills. You really get great bang for your buck. The pump is ideal for use with filtration systems and for creating waterfalls and watercourses.
