  • Motor is protected by double mechanical seals
  • Lower seal made of silicon carbide/silicon carbide and upper seal is made of carbon/ceramic
  • An additional lip seal has been installed above the impeller, to help prevent abrasives such as dirt, silt or sand, from entering the seal chamber

great for pond fountain

by mister ed

built my own pond fountain using one of these. wish it came with a longer cord, (50 ft. would be better) but added 25 more feet to make it work for my pond. use it about 8 hours each day with a timer. electric cost is neglible. keeps mosquito population down (breed on stagnant water) and distributes chemicals evenly. have less algae also. In northern climate and used from April throuigh October. In fourth year now (2017) and still works great. Remove it in Oct. each year.
