Description
The Aquascape 91020 AquaSurge® 5000 Pond Pump is a second-generation asynchronous submersible pump delivering 5,284 GPH at just 360 watts, ideal for ponds up to 5,000 gallons, large waterfalls, Pondless® Waterfall systems, and skimmer-based filtration. The maximum head height is 23.62 feet. A ceramic shaft with cooling port prevents overheating during 24/7 operation, and the threaded disconnect allows pump removal from skimmers without tools, hose clamps, or plumbing disassembly. The rotational ball output (1.5” or 2”) adjusts discharge angle to any position without extra elbows. Oil-free, fish-safe, and compatible with the Aquascape Smart Control system (receiver sold separately). 3-Year Limited Warranty. 120V / 3A. GFCI required.
Why Choose the Aquascape AquaSurge® 5000?
- Ceramic shaft with cooling port — overheating prevented: The unique ceramic shaft incorporates a dedicated cooling port that circulates pond water through the motor housing. This prevents thermal failure during continuous 24/7 operation and provides greater shaft durability than steel in aquatic environments.
- Threaded disconnect — tool-free service: The threaded disconnect allows the pump to be removed from any skimmer in seconds for maintenance or winterization — no tools, no hose clamps, no plumbing to disassemble. Reinstallation is equally fast.
- Asynchronous motor — high torque at altitude: Second-generation asynchronous technology provides high-torque performance at higher head heights compared to mag-drive pumps, delivering stronger flow up the waterfall. Saves hundreds of dollars per year over traditional direct-drive pumps at comparable output.
- Rotational ball output — install in any orientation: The 360°-rotating ball output fitting (1.5” or 2” adapter included) eliminates the need for extra elbows when fitting the pump into tight skimmer boxes or pump vaults. Aim the discharge anywhere without additional fittings.
- 23.62 ft maximum head height: Sufficient head for waterfalls up to approximately 20–22 ft with good margin. Pair with 2” plumbing to minimize friction losses and maintain strong flow at the spillway.
- Multi-hose adapter set included: Fits 1”, 1.25”, 1.5”, and 2” tubing for installation in any Aquascape skimmer, third-party skimmer, or Pondless® Waterfall vault without additional fittings.
- Oil-free, fish-safe, will not corrode or rust: Zero-contamination design — no oils, lubricants, or metals that can leach into the water. Safe for koi, goldfish, and aquatic plants in even the most sensitive installations.

Frequently Asked Questions
What is the maximum flow rate and head height of the AquaSurge® 5000?
The Aquascape 91020 AquaSurge® 5000 delivers a maximum flow rate of 5,284 GPH at zero head with a maximum head height of 23.62 feet. For a waterfall installation, flow decreases with head height — consult Aquascape’s published pump curve for your specific waterfall height.
Aquascape recommends 2-inch plumbing to minimize friction losses and maintain strong flow at the spillway.
How energy efficient is the AquaSurge® 5000 for 24/7 use?
The AquaSurge® 5000 consumes 360 watts at 3 amps (120V) — significantly less than conventional direct-drive pumps at comparable flow rates. The ceramic shaft with cooling port maintains thermal stability for continuous 24/7 operation without risk of overheating.
Is the AquaSurge® 5000 compatible with the Smart Control App?
Yes. When paired with an Aquascape Smart Control Receiver (sold separately), the 91020 supports the Aquascape Smart Control App for flow adjustment and custom scheduling. The receiver plugs into the pump’s cord and connects to your home Wi-Fi network.
For built-in Smart Control with a wireless remote and variable flow (no external receiver required), see the AquaSurgePRO — Item 45009 (up to 3,947 GPH variable) or Item 45010 (up to 7,793 GPH variable).
Can this pump handle solids and debris?
The AquaSurge® 5000 is designed for installation inside a pond skimmer or Pondless® Waterfall vault where the skimmer net pre-screens debris. The high-torque asynchronous motor passes small particles without clogging, and the oil-free design keeps the water clean.
The threaded disconnect makes pump removal for cleaning and winterization fast and tool-free — no hose clamps or plumbing to touch.
What fittings are included with the 91020?
The AquaSurge® 5000 includes a multi-hose adapter set for 1”, 1.25”, 1.5”, and 2” tubing, plus a rotational ball output in 1.5” and 2” sizes. The rotational ball output is a single discharge fitting that rotates 360° to aim flow in any direction, eliminating extra elbows in tight skimmer installations. An adjustable pump stand for vertical positioning is also included.
Is the AquaSurge® 5000 safe for fish?
Completely. The AquaSurge® 5000 uses an oil-free design — no lubricants can enter the water. It will not corrode or rust, maintaining water purity over years of continuous operation. Safe for koi, goldfish, and all aquatic plants.
How should I winterize my AquaSurge® 5000?
In freezing climates, remove the pump before ice forms:
- Use the threaded disconnect to remove the pump from the skimmer without tools.
- Clean intake and impeller with diluted white vinegar to remove mineral scale.
- Rinse and store in a frost-free location — submerged in a bucket of water to keep seals moist.
- Reinstall in spring using the threaded disconnect.
