Pumps
Webb's carries pond pumps for waterfalls, filtration, fountains, and pondless features in sizes from small water gardens to large koi ponds. The right pump matches your project type and delivers the flow you need at your actual head height.

How to Choose the Right Pond Pump
Choosing a pond pump comes down to two questions: what type of pump fits your project, and what size pump delivers the flow you need.
Match the Pump to Your Project
Submersible pumps are the simplest install for most backyard ponds — they sit underwater and push water up through your waterfall or filter. They're easy to maintain and work well for ponds up to a few thousand gallons.
External pumps sit outside the pond and pull water through the system. They run more efficiently than submersibles over long hours, which makes them the right choice for larger ponds, koi ponds running 24/7, or commercial circulation.
Fountain and statuary pumps are smaller pumps sized for the spray height you want. They also work well as accent pumps in water features where you don't need full pond circulation.
For complete pondless waterfalls or new pond builds, pump kits bundle a properly sized pump with a filter and UV clarifier so you don't have to size each piece separately.
Size by Flow and Head Height
Once you've picked the pump type, size it by GPH (gallons per hour) at your actual head height. Head height is the total vertical lift from the pump to the highest point in your system, plus friction loss from your plumbing.
This matters because pump flow drops as head height increases. A pump rated for 4,000 GPH at the discharge might only deliver 2,500 GPH at 10 feet of head. Manufacturer flow curves show the real performance at different heights — always size based on flow at your head height, not the headline GPH number.
As a starting point: for waterfalls, plan for 1,500 GPH per foot of waterfall width. For filtration, your pump should turn over your full pond volume every 1-2 hours.
When to Talk to a Pond Tech
Pump sizing is one of the most common reasons customers call Webb's. If you're unsure about your head height, dealing with a complex plumbing run, or building a system with multiple features (waterfall + filter + fountain), our pond techs can save you from over- or under-sizing. Contact a pond tech — no charge, no upsell pressure.
