Submersible, external and solids-handling pumps compared: sizing, efficiency and what to ask before buying.
A pond pump moves water through filters, up to a waterfall and around the pond. Choosing the right one means matching flow, lift and efficiency to the system. A pump that is too strong wastes electricity. One that is too weak leaves the water stagnant.
Submersible pumps sit in the water and are simple and affordable. External pumps sit beside the pond, are efficient and easier to service. Solids-handling pumps pass leaves and debris and suit ponds without a good skimmer. Variable-speed pumps let you adjust the flow to save power.
Simple, quiet and common.
Efficient and easy to service.
Pass leaves and debris.
Save energy with adjustable flow.
Real flow depends on height.
Match the pump to the job.
