Little Giant Cast Iron Pump 9S-CIM - 4,800 gph

Remember every fish pond needs a pump that runs 24/7 to be able to supply life-giving oxygen to your biofilter. It is vital therefore to choose a pond pump with at least 2 years guarantee and one that runs with low power consumption in order to keep the running cost down. Most fish ponds will go green in summer especially unless you install an Ultra Violet Light (sometimes called sterilizer or clarifier or UVC). The UVC kills the suspended algae responsible for green or brown murky water. 

Product and Supplier Information

Little Giant Pump Company's origins date back to 1941, when an idea by a plumber named Doc Wolfe became the answer to water circulation for evaporative cooling. Called "a submersible vaporizer," this unique, patented pump design became the cornerstone for the hundreds of different pump models Little Giant Pump Company manufacturers and ships worldwide today. In fact, derivatives of that basic "self-contained electric motor-driven submersible pump" are now a standard for quality and reliability for applications in parts washers, tile saws, carpet cleaning machines, water coolers and drainage systems. In addition to a full line of wastewater, sump, effluent and sewage pumps, Little Giant Pump Company manufactures condensate pumps, magnetic drive pumps, pool cover pumps and a wide variety of utility pumps. … Little Giant Cast Iron Pump 9S-CIM - 4,800 gph
