Play It Koi sells pumps for everything from 1,000-gallon water gardens to 20,000-gallon koi systems running several pumps, and the notes below come from helping customers choose and run them.
Every pump here is one we carry. Each gets its pros and cons, because the right pump for a 2,000-gallon backyard pond is very different from the right pump for a 15,000-gallon show pond.
If you're new to pond pumps, start with our Complete Koi Pond Pump Guide for the fundamentals. If you already know what type and size you need, this is where you pick the exact pump.
Three things matter more than the brand name. The first is energy efficiency: a pump runs 24/7/365, so electricity is often its biggest long-term cost. The second is reliability, because a dead pump can kill fish. The third is real flow at your actual TDH, not the max GPH printed on the box.
For most koi ponds, our first recommendation is the PerformancePro Cascade Low RPM, a quiet, efficient external pump. The Anjon Landshark is the lowest-priced external line we carry. For a submersible, the OASE AquaMax Eco Expert adds seasonal flow control, frost protection and a dry-run shutoff, with a five-year warranty once you register it. Whatever you pick, size it by its flow at your real TDH, not its max GPH.
How we evaluate pumps
Every pump on this page is one we carry and have had enough customer feedback on to form an opinion. Here is what we look at:
- Flow at real-world TDH. The max GPH printed on the box is measured at zero head. Most koi ponds run at 8 to 15 feet of total dynamic head once you count pipe friction, elbows and vertical lift. If you're not sure what yours is, read our TDH explainer.
- Energy efficiency (watts per GPH). A pump that costs $200 less upfront but draws 300 more watts costs about $473 more a year in electricity at $0.18/kWh, the U.S. average, so we look at three-year cost of ownership.
- Build quality and serviceability. Can you get replacement parts? Can you service it yourself? Is the motor potted or rebuildable?
- Warranty. It tells you how long the manufacturer expects the pump to hold up.
- Customer feedback. What our customers report after months and years of daily use.
If you need help figuring out what size pump your pond needs, use our Pond Pump Calculator. It accounts for pond volume, TDH, and turnover rate.
Best external koi pond pumps
External pumps sit outside the pond in a dry location. For most koi ponds over 1,000 gallons, an external pump is what we recommend: they hold their flow well against head, they're easier to service, and they tend to last longer than submersibles. Here are the external pumps we carry, in our order of recommendation.
1. PerformancePro Cascade Low RPM: our first choice
Starting price: see current price | View the listing
If we could recommend only one pump, this would be it. The Cascade Low RPM is quiet, efficient and reliable, and it's the external pump we recommend most often. Its 1,725 RPM motor is totally enclosed and built for quiet running, and the slower motor means less wear, less heat and lower energy bills without giving up the flow a koi pond needs.
PerformancePro makes it in five sizes, from 36 GPM (about 2,160 GPH) for the 1/8 HP C1/8-22 to 81 GPM (about 4,860 GPH) for the 1/4 HP C1/4-49, both maximum flows, so there's a Cascade Low RPM for most ponds from about 2,000 to 8,000 gallons.
Cap'n Brien Spina's raised koi pond, one of our favorite customer builds, runs on a PerformancePro Artesian2 Low RPM 1/2 HP, a bigger pump from the same maker's low RPM range. Read his full story here.
| Type | External, low RPM (1,725 RPM) |
| Flow | 36 to 81 GPM max (about 2,160 to 4,860 GPH) by size; 15.4 to 22.4 ft max head |
| Motor | 1/8 HP or 1/4 HP; 130 to 340 W max by size (PerformancePro) |
| Warranty | 3 years (1 year in saltwater) |
Pros:
- High-efficiency pump and motor, per PerformancePro
- Quiet: totally enclosed 1,725 RPM motor
- Proven long-term reliability
- Five sizes to match your system
- Easy to service
Cons:
- Costs more upfront than the Landshark
- Needs a dry, protected spot, and works best with flooded suction
Best for: Primary circulation on 2,000 to 8,000 gallon koi ponds.
2. PerformancePro Cascade High RPM: for more head and flow
Starting price: see current price | View the listing
Same PerformancePro build as the Low RPM, with a 3,450 RPM motor that pushes much more water. You give up some efficiency and quiet for raw flow, and some systems need exactly that.
If you have a tall waterfall (6 feet or more of vertical lift), a long plumbing run, or another high-TDH system, the High RPM handles it where the Low RPM falls short. It also works well as a dedicated waterfall pump in a two-pump setup.
| Type | External, high RPM (3,450 RPM) |
| Flow | 38 to 146 GPM max (about 2,280 to 8,760 GPH) by size; 55 to 85.6 ft max head |
| Motor | 1/3 HP to 2 HP; 600 to 1,930 W max by size (PerformancePro) |
| Warranty | 3 years (1 year in saltwater) |
Pros:
- High flow for demanding systems
- PerformancePro build quality and support
- Reasonable price for the flow delivered
Cons:
- Uses more electricity than the Low RPM
- Louder than the Low RPM
- More pump than most standard koi ponds need
Best for: Tall waterfalls, high-TDH systems, and dedicated waterfall pumps in two-pump setups.
3. Sequence Power 4000: high flow at high head
Price: see current price | View the listing
Sequence built the Power 4000 for recirculation jobs that need more than 8,000 GPH at high head. The two models reach 11,160 and 13,200 GPH and about 81 feet of head, and the 2-inch ports take union adaptors directly, so you skip the reducer fittings and the friction they add. It is assembled in the USA, at the maker's Colorado facility, and uses a TEFC fan-cooled motor. The 3 HP motor is rated up to 2,162 W (11200PWR81) or 2,595 W (13200PWR81), so the Power 4000 makes the most sense on a system that needs its flow at high head. The data sheet linked on the listing shows the flow at each head.
The Sequence has a larger footprint than most residential pumps, which matters in a tight equipment area. If you have the space, it is a pump you can install and leave alone for a long time.
| Type | External, TEFC fan-cooled motor (3 HP) |
| Flow | 11,160 or 13,200 GPH max; about 81 ft max head |
| Wattage | 2,162 W (11200PWR81) or 2,595 W (13200PWR81) max |
| Warranty | 3 years (limited) |
Pros:
- Built for high flow at high head
- 2-inch ports with union-adaptor threads, so fewer reducers and less friction
- TEFC fan-cooled motor
- Assembled in the USA (Colorado)
Cons:
- Costs more upfront than most residential pumps
- High power draw: up to 2,162 or 2,595 W
- Large physical footprint
- More pump than most backyard ponds need
Best for: Large ponds (5,000 to 15,000+ gallons), professional builds, and koi keepers who put long-term reliability ahead of upfront cost.
4. Anjon Landshark: the lowest-priced external line we carry
Starting price: see current price | View the listing
If you're moving from a submersible to your first external pump and want to keep the cost down, the Anjon Landshark is where to start. It's a solid, no-frills external pump that makes external pumping affordable.
You get the main advantages of an external pump, a serviceable unit outside the pond, for less than a Cascade. The Landshark adds a removable oversized debris basket under a clear quick-release cover, a self-balancing impeller for vibration-free running, and a thermal sensor that stops it overheating. As a first external pump or a backup external pump, it earns its spot.
| Type | External |
| Flow | 2,000 to 5,575 GPH (four sizes); 20 to 40 ft max head |
| Wattage | 250 to 1,100 W by size (Anjon) |
| Warranty | 2 years |
Pros:
- Lowest starting price of the external pumps we carry
- Built-in oversized debris basket with a clear cover
- Four sizes, 2,000 to 5,575 GPH
- Good entry point into external pumping
Cons:
- Two-year warranty, against three for PerformancePro and Sequence
- Needs a dedicated 15 A GFI circuit, per Anjon
- Fewer sizes than the Cascade or Monsoon lines
Best for: Lower-cost builds, first external pump upgrades, and secondary or backup external pumps.
5. EasyPro VSP165: variable speed on an external pump
Price: see current price | View the listing
Want variable speed on an external pump? The EasyPro VSP165 lets you set the motor speed from a digital keypad, so you can match the flow to your system and cut the electricity. It's rated up to 8,200 GPH and 65 feet of head, which covers most medium to large koi ponds.
| Type | External, variable speed (totally enclosed fan-cooled motor) |
| Flow | Up to 8,200 GPH; up to 65 ft of head |
| Power | 1.65 HP, 208 to 230 V. EasyPro doesn't publish watts; the draw varies with speed, so check the nameplate |
| Warranty | 2 years |
Pros:
- Set the speed to the flow you need
- Large energy savings at reduced speed
- Totally enclosed fan-cooled motor needs no weather cover
- Large suction strainer and unions included
Cons:
- No power cord: it's built to be hard-wired
- Not self-priming, so it needs a check valve or flooded suction
- Needs a 208 to 230 V circuit
Best for: Medium to large ponds that want variable speed on an external pump. It's our pick for that job.
Best submersible koi pond pumps
Submersible pumps sit in the water. They're simpler to install, with no external plumbing or pump house, and they work well for smaller ponds, backup duty, and places where an external pump isn't practical. The trade-off is that they're harder to service and generally don't last as long as externals. Here are the submersibles we carry.
1. OASE AquaMax Eco Expert: our top submersible pick
Starting price: see current price | View the listing
If you need a submersible and don't want to compromise on quality, this is it. The German-engineered AquaMax Eco Expert uses a brushless DC motor, can run submerged or inline, and has OASE's Seasonal Flow Control, which lowers the flow and pumping height as the water cools (OASE says this can save up to 50% of the energy). It also shuts itself off on a dry run or blockage, and its frost protection is rated down to -4°F.
It costs more than other submersibles; an Anjon Monsoon of similar flow costs far less. What you pay for is the control and protection: adjustable flow through an OASE Easy Garden Control (EGC) controller and app, the dry-run shutoff, and a warranty that runs five years once you register the pump online.
| Type | Submersible or inline |
| Flow | 6,800 or 11,500 GPH max (230 V models); 5,300 and 7,100 GPH 12 V models are also listed |
| Power | 440 W (6800) or 730 W max (11500) |
| Warranty | 3 years, plus 2 more with online registration |
Pros:
- Seasonal Flow Control can cut energy as the water cools
- Stainless steel intake screen; passes solids up to about 0.44 inch
- Dry-run and blockage shutoff, frost protection to -4°F
- Five-year warranty with registration
Cons:
- Costs much more than other submersibles
- The 6800 and 11500 models run on 230 V
- Still harder to service than an external pump
Best for: When you need submersible placement but don't want to compromise on quality or longevity. Also a good fit for pond-in-pond setups.
2. Anjon Monsoon: our backup pump pick
Starting price: see current price | View the listing
The Anjon Monsoon is the pump we recommend most as a backup pump. It costs little enough that every koi keeper can keep one in the pond, plumbed in and ready to go, and it's also a capable primary pump for smaller ponds and lower-cost builds.
The Monsoon comes in more sizes than any other pump here, from 550 to 15,000 GPH, and its listed power draw is low for its flow: the MS-3000 is rated 3,000 GPH at 192 W. Its oil-free motor is safe for fish, it's built for 24-hour running with a heat-overload sensor, and most models work with Anjon's optional variable speed controller.
| Type | Submersible, asynchronous |
| Flow | 550 to 15,000 GPH |
| Power | 54 W (MS-550) to 1,100 W (MS-15000) |
| Warranty | 2 years |
Pros:
- Lowest starting price of any pump here
- Widest range of sizes
- Low listed power draw for its flow
- Easy to keep as a backup
Cons:
- Two-year warranty
- Submersible, so servicing means pulling it from the pond
Best for: Backup pumps (our first recommendation for that job), small ponds, and builds where upfront cost matters most.
3. Evolution Aqua Adjustable Flow: a variable speed submersible
Price: see current price | View the listing
A submersible with adjustable flow is a useful combination. The Evolution Aqua controller takes the motor from 0 to 100% power and shows the watts it is drawing at each setting, so you can dial the flow to your system and see what you save. Turned down, it's very efficient and very quiet.
| Type | Submersible or external flooded, variable speed |
| Flow | Up to 2,642 GPH; 10 ft max head (VP10) |
| Power | 90 W max (Evolution Aqua); the display shows the operating watts |
| Warranty | 2 years |
Pros:
- Variable speed in a submersible
- Controller shows the watts at each setting
- Quiet operation
- Can also run outside the pond in a flooded setup
Cons:
- Tops out at 2,642 GPH and 10 feet of head
- Not for high-flow systems
Best for: Water gardens and smaller koi ponds that want submersible convenience with variable speed.

Energy cost of every pump reviewed
A koi pond pump runs 24 hours a day, 365 days a year, so electricity is often the biggest ongoing cost of a pond. The table shows each maker's power figure for the pump line, the yearly electricity that works out to, and the three-year cost of ownership: purchase price plus three years of electricity. Our pump energy cost guide has a calculator for your own numbers.
Yearly electricity runs the pump 24/7 at $0.18/kWh, the U.S. average residential rate. Rates are from the U.S. Energy Information Administration's July 2026 data, checked October 21, 2026. The power figures are the makers' own, and most are maximums, so a pump running at your head usually draws less. EasyPro doesn't publish watts for the VSP165, so read them off the nameplate. Your costs will vary with the model size, your rate and your system's head, so use these for comparison, not exact budgeting.
| Brand | Model | Type | Maker's power figure | Electricity per year @$0.18 | 3-year cost | Link |
|---|---|---|---|---|---|---|
| PerformancePro | Cascade Low RPM | External | 130 to 340 W max (by size) | $205 to $536 | see current price to see current price | View |
| PerformancePro | Cascade High RPM | External | 600 to 1,930 W max (by size) | $946 to $3,043 | see current price to see current price | View |
| Sequence | Power 4000 | External | 2,162 or 2,595 W max | $3,409 or $4,092 | see current price or see current price | View |
| Anjon | Landshark | External | 250 to 1,100 W (rated, by size) | $394 to $1,734 | see current price to see current price | View |
| EasyPro | VSP165 | External (VS) | Not published; varies with speed | From the nameplate | see current price, plus electricity | View |
| OASE | AquaMax Eco Expert | Submersible | 440 W (6800) or 730 W max (11500) | $694 or $1,151 | see current price or see current price | View |
| Anjon | Monsoon | Submersible | 54 W (MS-550) to 1,100 W (MS-15000) | $85 to $1,734 | see current price to see current price | View |
| Evolution Aqua | Adjustable Flow VP10 | Submersible (VS) | 90 W max | Up to $142 | see current price | View |
Key takeaway: The cheapest pump to buy isn't always the cheapest to own. At $0.18/kWh, every 100 watts of continuous draw costs about $158 a year, or $473 over three years, so compare listed watts at the flow you need before you compare price tags. Use our Pond Pump Calculator to find the right size for your system.
Why we recommend a backup pump
Whichever pump you choose as your primary, we strongly recommend adding a second pump as a backup. We say it in our pump guide too: a pump failure on a hot summer night can kill fish in hours, and a backup pump costs far less than the fish it protects.
Our usual recommendation is an Anjon Monsoon MS-2000 (see current price). It sits in the pond, takes up little space, and can keep your fish alive for days while you replace the primary pump. Plumb it into your return line, keep it plugged in (or on a transfer switch), and leave it until you need it.
For larger ponds (5,000 gallons or more), consider the Monsoon MS-4000 (see current price) or a second external pump. Your koi are worth far more than the backup pump.
Don't forget a pre-strainer
Every external pump needs a strainer basket or leaf trap on the suction side. Without one, debris will eventually damage the impeller or cut the flow, and that's a repair bill you don't need.
- External pumps: Put a strainer basket before the impeller to catch leaves, sticks and large debris. The Landshark has an oversized debris basket built in, and the EasyPro VSP165 comes with a large suction strainer. For the Cascade and Sequence pumps, install an inline strainer basket before the pump.
- Submersible pumps (OASE, Monsoon, Evolution Aqua): Use the intake screen and check it regularly for clogging. If your pond carries a heavy debris load, consider a pre-filter.
- Bottom drain systems: Put a pre-filter or settling chamber before the pump, especially with an external pump in a gravity-fed system.

Frequently asked questions
Which pump brand is most reliable?
In our experience selling and supporting these brands: PerformancePro and Sequence for external pumps, and OASE for submersibles. Every pump on this page is one we're comfortable selling, though, and reliability depends more on how a pump is installed and maintained than on the brand.
Is a more efficient pump worth the higher price?
Usually, yes. A pump that draws 200 W less, running 24/7, saves about $315 a year at $0.18/kWh. If it costs $400 more, it pays that back in about 15 months, and the savings keep coming for as long as it runs. Our pump energy cost guide has a calculator for your own numbers.
Can I use two different brands together?
Yes. A common setup is a PerformancePro Cascade on the filtration loop with an Anjon Monsoon as the backup, or a Sequence on filtration and a PerformancePro on the waterfall. The pumps don't need to match; each just needs to be sized for its own job.
How do I know which size pump to get?
Use our Pond Pump Calculator. You'll need your pond volume in gallons, your target turnover (usually 1 to 2 times per hour for koi ponds), and your system's total dynamic head (TDH). The calculator gives you a target GPH; then pick the pump that delivers that flow at your TDH, not at zero head.
Do I need a variable speed pump?
Not necessarily. Variable speed pumps save energy and give you flexibility, but a correctly sized fixed-speed pump works well for most koi ponds. If the variable speed models are beyond your budget, a PerformancePro Cascade Low RPM is a sound fixed-speed choice.
What warranty do these pumps come with?
It varies. OASE gives three years, plus two more if you register the pump online. PerformancePro gives three years in freshwater (one in saltwater), and Sequence a three-year limited warranty. Anjon, EasyPro and Evolution Aqua give two years. Register your pump with the manufacturer, since some warranties depend on it, and keep your receipt.
