Maxspect Jump DC Pump 8K — 2,113 GPH

Powerful, Quiet & Precisely Controllable Return Flow for Serious Reef Systems

Your return pump is one of the most important pieces of equipment in your aquarium. It keeps water moving between your display and sump, feeds your filtration system, and helps maintain the circulation your reef depends on 24/7.

The Maxspect Jump DC Pump 8K combines serious flow capacity with the control and quiet operation reefers expect from a modern DC return pump.

Delivering up to 2,113 GPH, the Jump 8K gives you substantial flow capacity while allowing you to precisely adjust output to match your aquarium, plumbing, overflow, and filtration system.

And with Maxspect's Sine Wave Technology, the Jump 8K is designed to deliver powerful circulation without the excessive vibration and noise associated with many traditional return pumps.

More Flow. More Control. Less Noise.

That's what makes the Maxspect Jump DC 8K such a strong choice for demanding reef systems.

Why Choose the Maxspect Jump DC 8K?

Up to 2,113 GPH of Adjustable Flow

The Jump 8K delivers a maximum flow of 8,000 L/H / 2,113 GPH, giving your reef system substantial return capacity.

But maximum flow isn't always the goal.

Your ideal return flow depends on your aquarium size, overflow capacity, plumbing, vertical lift, filtration equipment, and the type of reef you're running.

That's why the Jump 8K allows you to adjust the pump output instead of forcing you to operate at one fixed speed.

BRS lists an adjustable operating range of approximately 898–2,113 GPH.

This gives you the flexibility to:

• Fine-tune your aquarium's turnover
• Match flow to your overflow
• Balance return flow with your sump
• Reduce unnecessary turbulence
• Adjust for different filtration equipment
• Increase flow as your reef grows
• Dial in your system after changing plumbing

Run the flow your reef needs—not simply the maximum flow your pump can produce.

Near-Silent Sine Wave Technology

A return pump operates continuously, which means pump noise can quickly become one of the most noticeable sounds coming from an aquarium.

Maxspect's Sine Wave Technology is designed to produce smoother electrical current and smoother motor operation.

Instead of the sharper electrical waveform used by traditional pump technology, the Jump series uses a smoother sine-wave pattern to help reduce vibration and operating noise.

The result is a return pump designed to deliver substantial flow while remaining remarkably quiet.

Your reef should be what you hear—not your return pump.

20 Speed Settings for Precise Control

The Jump 8K includes an external controller with 20 different flow-speed settings, giving you plenty of flexibility to fine-tune your return system.

This is particularly useful when your aquarium changes over time.

Adding a new filtration device?
Changing your plumbing?
Increasing livestock?
Running a different overflow rate?

Simply adjust the pump.

You don't need to replace your return pump every time your reef evolves.

Built-In Feed Mode

Feeding time is easier with the Jump 8K.

The controller includes three selectable Feed Mode durations: 10, 20, or 30 minutes.

With the push of a button, you can temporarily reduce return flow while feeding and allow your fish time to eat without immediately sending food into the overflow and filtration system.

When Feed Mode ends, the pump returns to normal operation.

Two Pulse Modes

The Jump 8K also includes two pulse modes, providing additional flexibility for reefers who want to experiment with water movement and circulation.

While the pump's primary role is return circulation, these modes give advanced hobbyists another tool for configuring their aquarium's flow strategy.

14.7 Feet of Maximum Head

Maximum GPH doesn't tell the whole story.

Your return pump has to push water vertically from the sump to the display, and every foot of elevation, elbow, fitting, valve, and restriction can reduce actual flow.

The Jump 8K provides up to 4.5 meters / 14.7 feet of maximum head height, giving it strong head-pressure capability for real-world sump installations.

WWC Tip

Never size a return pump based only on its maximum GPH.

Determine the vertical distance from your pump to the display and account for your plumbing restrictions before deciding how much pump capacity you need.

A pump rated at 2,113 GPH at zero head will not deliver 2,113 GPH at your aquarium's actual operating height.

Built for Changing Reef Systems

One of the biggest advantages of a controllable DC return pump is flexibility.

Your aquarium isn't static.

You may eventually:

• Add more fish
• Increase feeding
• Upgrade your filtration
• Add a UV sterilizer
• Add a refugium
• Change plumbing
• Modify your overflow
• Increase or decrease desired turnover

The Jump 8K gives you the ability to adjust return flow as your system changes.

Build your reef around a pump that can grow with it.

Compact Enough for Real-World Sumps

Despite its 2,113 GPH capacity, the Jump 8K uses the same compact pump-body dimensions as the Jump 6K.

The pump measures approximately:

7" × 3½" × 3"

and weighs approximately 2.3 lb.

That compact footprint makes it easier to install in sumps where space is limited.

The MJ-DC8K also supports 1" and 1¼" output connections, giving you flexibility when selecting your plumbing configuration.

Efficient DC Performance

The Jump 8K is rated at 90W maximum power consumption.

Because the pump is controllable, you don't have to run it at maximum output when your aquarium doesn't require it.

That allows you to balance performance and power consumption based on the actual needs of your system.

Is the Maxspect Jump 8K Right for Your Aquarium?

The Jump 8K is an excellent choice for reefers who need more return capacity than the 6K while maintaining the same compact pump design and controllability.

It's especially well suited for:

• Medium-to-large reef aquariums
• Mixed reef systems
• SPS-dominant aquariums
• Heavily stocked systems
• Large fish populations
• High-flow filtration systems
• Custom reef builds
• Systems with significant vertical lift
• Reefers planning future upgrades
• Aquariums requiring adjustable return flow

WWC Recommendation

If you're choosing between the Jump 6K and Jump 8K, don't simply ask which one has more GPH.

Ask:

How much flow do I need at my actual operating head?

If your system requires more capacity or you want additional headroom for future upgrades, the Jump 8K is the better choice.

Why We Like It

The Jump 8K hits a sweet spot for reefers who need serious return capacity without jumping into a much larger pump footprint.

You get:

✔ 2,113 GPH maximum flow
✔ 14.7 ft maximum head
✔ 20 speed settings
✔ Near-silent Sine Wave Technology
✔ Feed Mode
✔ Two pulse modes
✔ Compact 7" × 3½" × 3" design
✔ 1" and 1¼" output options

It's a pump that gives you the capacity to handle a demanding reef while still allowing you to dial the system back when full output isn't necessary.

WWC Tip: Don't Buy More Pump Than Your System Can Use

A bigger return pump isn't automatically a better return pump.

Your goal is to find the right balance between:

Display turnover + filtration requirements + overflow capacity + head pressure + plumbing restrictions.

The Jump 8K gives you enough capacity to start high and dial the flow back to exactly where your system performs best.

And if your reef grows, you already have additional capacity available.

The Return Pump Your Reef Can Grow Into

A return pump isn't just another piece of equipment in your sump.

It is the connection between your display and your entire filtration system.

The Maxspect Jump DC Pump 8K gives you the combination of 2,113 GPH maximum flow, 14.7 feet of head pressure, 20 speed settings, Feed Mode, pulse modes, and Sine Wave Technology needed to build a return system that is powerful, quiet, and adaptable.

Whether you're upgrading an existing reef or building a new system from the ground up, the Jump 8K gives you the ability to dial in your return flow today while keeping additional capacity available for tomorrow.
