Description
The Atlantic TT5000 TidalWave3 (Item 73928) is an ultra-high efficiency asynchronous submersible pond pump delivering 5,150 GPH at 310 watts. The asynchronous motor design combines magnetic induction efficiency with direct drive power geometry, producing up to 35% energy savings compared to the previous TW-Series while moving more water per watt than ever. At 9¼”L × 6”W × 7”H, the compact body fits the tightest pump vaults and skimmers, and the 2” MIPT inlet / 2” FIPT outlet supports high-volume flows with minimal restriction. The pump runs vertically or horizontally and includes a 2” Insert barbed fitting for flexible hose connection. A quarter-turn volute provides tool-free impeller access for cleaning and rotor chamber maintenance. The stainless-steel cooling screen resists fouling in hard water, and the thermal overload protection safeguards the motor from debris blockages. Compatible with the separately sold Atlantic Variable Speed Controller (TWVSC) for wireless remote and mobile-app flow control in 10 adjustment levels. 20 ft cord. cULus listed. 3-year warranty. GFCI-protected 120V outlet required.
Why Choose the Atlantic TT5000 TidalWave3?
- Asynchronous motor — up to 35% more efficient than TW-Series: The TidalWave3 asynchronous design combines the efficiency of magnetic induction with the high-torque power of direct-drive geometry. The result is more gallons per watt than conventional mag-drive or direct-drive pumps, delivering 5,150 GPH at just 310W — approximately 66 watts per 1,000 GPH — making it ideal for continuously operated water features where energy cost matters.
- Water-cooled rotor — submersible only: The TT5000 rotor is cooled by the surrounding pond water through a stainless-steel cooling screen. The pump must be fully submerged at all times of operation. The stainless-steel screen keeps grit out of the rotor chamber; regular cleaning of the screen prevents overheating and extends pump life. This is a distinct maintenance step from cleaning the pre-filter.
- Quarter-turn volute — tool-free maintenance: The pump volute (front cover) removes with a single quarter-turn rotation for immediate impeller access. No tools, no screws, no disassembly. Cleaning the impeller, clearing debris from the rotor chamber, and replacing the impeller assembly (Part 75342) are all achievable in the field without specialized tools.
- Compact body fits the tightest pump chambers: At 9¼” long × 6” wide × 7” tall, the TT5000 is sized to fit the internal chambers of Atlantic’s Big Bahama FilterFalls (BF2600), Classic SkimmerFilters, and pond-free pump vaults. It installs horizontally or vertically to match your skimmer or vault orientation.
- Hard water tolerant and clog-resistant: The TT-Series is specifically engineered for hard water environments — a key specification for Indiana, Ohio, and Midwest installations where calcium and mineral deposits degrade competing pumps. The ribbed pre-filter screen and handle provide extended surface area for greater clog resistance, reducing maintenance frequency.
- 2” MIPT inlet and 2” FIPT outlet: The step up to 2” connections at the TT5000 (vs 1½” on smaller TT models) reduces flow restriction and supports the full 5,150 GPH output. The included 2” Insert barbed fitting connects directly to flexible pond hose without additional adapters. Ensure your skimmer outlet and return plumbing are sized for 2” to maximize performance.
- TWVSC variable speed control (sold separately): The Atlantic Variable Speed Controller (TWVSC) pairs wirelessly with all TT-Series asynchronous pumps. Control pump output from 25% to 100% in 10 steps via the included remote control or the Atlantic mobile app, set scheduled on/off times, and adjust waterfall flow seasonally — all without wiring changes.
- 3-Year Warranty, cULus Listed: Backed by Atlantic’s 3-year manufacturer warranty and independently safety-listed to cULus standards (Listing #E318238).

Frequently Asked Questions
What are the benefits of the TT5000 asynchronous motor design?
The TT5000 asynchronous motor combines magnetic induction efficiency with the high-torque output of direct drive geometry. This dual-technology approach delivers up to 35% better energy efficiency compared to Atlantic’s previous TW-Series mag-drive pumps, producing more gallons per watt across all head heights.
The result at the TT5000 scale: 5,150 GPH at just 310 watts — roughly 66 watts per 1,000 GPH. For a continuously operated water feature running 24/7, this efficiency directly reduces annual electricity costs compared to conventional direct-drive pumps of similar output.
The optional Atlantic Variable Speed Controller (TWVSC) pairs wirelessly with the TT5000 to adjust output from 25% to 100% in 10 levels via remote or mobile app, enabling further seasonal energy reduction when full flow is not needed.
How much water does the TT5000 move at different head heights?
The TT5000 TidalWave3 delivers 5,150 GPH at 0 feet of head (free-flow). Output decreases as waterfall height increases, with a maximum shut-off head of 21 feet. For best performance, calculate your actual installation head height (the vertical rise from pump to waterfall outlet) and verify against Atlantic’s published flow curve.
For precise flow rate at your specific installation height, refer to Atlantic’s official TT-Series Flow Chart available on their product page at atlantic-oase.com. As a general guide, the TT5000 is well-suited for waterfalls and streams up to approximately 15 feet of head while still delivering strong flow. For installations approaching 20 feet of head, consider the TT6000 for greater margin.
Is the TT5000 a solids-handling pump?
Yes. The TT5000 uses a three-vane hybrid impeller that passes solid debris — pine needles, fish waste, algae, and small particulates — without clogging. This makes it ideal for pond skimmer and pump vault installations where debris-laden water passes directly through the pump before filtration.
Unlike fine-clearance mag-drive pumps that require pre-filtration before the pump, the TT5000 can handle organic debris that would block a mag-drive impeller. The large-opening ribbed pre-filter screen provides additional clog resistance as a first layer of protection while maintaining flow through extended operating periods between cleanings.
Can the TT5000 be installed horizontally or vertically?
Yes. The TT5000 installs in either orientation — horizontal (the most common configuration in pond skimmers and pump vaults) or vertical (for pump vault configurations where space requires it).
Important: Regardless of orientation, the pump must be fully submerged at all times of operation. The TT-Series uses a water-cooled rotor — the surrounding water is the motor’s thermal management system. Running the pump outside of water, even briefly, overheats the motor and causes permanent failure. The warranty is voided if the pump is operated while not fully submersed.
Ensure your skimmer or pump vault maintains water level above the top of the pump housing during all operating conditions, including during low-water events.
What is the warranty and how do I maintain the TT5000?
The Atlantic TT5000 is backed by a 3-year manufacturer warranty and is cULus safety-listed (E318238).
Key maintenance steps:
- Pre-filter screen: Remove and rinse the ribbed pre-filter screen regularly to maintain flow. Unlock the latches on either side of the pre-filter by pulling outward, then slide the pre-filter off.
- Stainless-steel cooling screen: Clean the rotor cooling screen periodically. The rotors are water-cooled; a clogged cooling screen causes overheating. Remove the quarter-turn volute for access.
- Quarterly impeller check: Remove the volute with a quarter-turn rotation (counterclockwise, no tools needed) and inspect the impeller for debris or mineral buildup.
- Winter storage: If your pond freezes, remove the pump, drain it, clean it, and store in a cool, dry location until spring. Do not leave the pump in a frozen pond.
Replacement parts available: Impeller Assembly (Atlantic part 75342), Intake Kit (77056), Handle (75398).
