EZ-Clone Replacement Water Pumps – 1125 GPH

The EZ-Clone Replacement Water Pump — Mag 1125 (EZWP1125) is the top-tier pump in EZ Clone’s Mag Drive line, rated at 1,100 GPH and sized to power the manifolds of the EZ-Clone Original 128-site aeroponic cloning system. Its magnetic-drive design uses a plastic-coated impeller and no motor seals, so there are no leak points and no oil to maintain. It ships with an adjustable filter to keep large debris out of the misters and is backed by EZ Clone’s limited lifetime warranty.

Why Choose the EZ-Clone Mag 1125 Pump

This is a replacement pump engineered around a small number of deliberate design choices. EZ Clone’s Mag Drive line is what ships inside the company’s own aeroponic cloning systems, so the Mag 1125 is not a third-party substitute — it is the same pump the manufacturer has validated against its own manifolds and misters. For growers replacing a worn unit or building a spare into the maintenance kit, these are the practical reasons it matters.

• Magnetic-drive, oil-free construction: A mag drive uses a magnetic coupling between the motor and impeller instead of a directly-coupled shaft. There is no shaft seal to wear out and no oil reservoir to leak. In a recirculating aeroponic system, that means no oil sheen on the reservoir water and no slow seepage to track down years into a build.
• One moving part: The plastic-coated impeller is the only moving part inside the pump. Fewer moving parts means fewer wear points and a longer service interval. EZ Clone publishes this as a deliberate engineering choice, not a side effect of the magnetic-drive design.
• Low heat generation: Submersible pumps that run continuously inside a sealed reservoir can warm the nutrient solution — an issue for root health in aeroponic cloners where dissolved oxygen and pathogen suppression both depend on reservoir temperature. EZ Clone designs the Mag Drive line to minimize heat transfer into the water.
• Adjustable debris filter included: The pump ships with an adjustable filter cage that mounts to the inlet. In an aeroponic cloner, the misters are the narrowest restriction in the flow path; the filter is what keeps biofilm, root fragments, and rockwool fibers from clogging them.
• Limited lifetime warranty: EZ Clone backs the Mag Drive pumps with a limited lifetime warranty. That is unusual for a submersible pump at this price point and reflects the simplicity of the internal design.
• Manifold-matched flow: The 1,100 GPH rating is sized to the manifold and mister count of the EZ-Clone Original 128-site system. Using a smaller pump in a 128-site setup under-pressures the manifold and produces inconsistent mist patterns at the far stations; using a larger third-party pump risks over-pressuring the manifold joints.

Best Uses for the Mag 1125 Pump

The Mag 1125 is the right pump for one primary application and a small number of adjacent ones. It is purpose-built for a specific system; if your application falls outside that scope, one of the smaller Mag Drive pumps may be the better choice and the cost difference is meaningful.

• EZ-Clone Original 128-site replacement: Direct drop-in replacement for the pump originally shipped with the 128-site EZ-Clone Original aeroponic cloning system. This is the design fit and the application the pump is specified against.
• Spare pump for production propagation: Commercial nurseries running continuous propagation cycles benefit from a tested spare on the shelf. A failed pump means a stalled flush of clones; same-day pump swap is the difference between a missed week and a full crop loss.
• Upgrade path from a smaller cloner: If you are moving up from a 32-site or 64-site cloner to the 128-site system, the Mag 1125 is the matched pump for the new chamber. You can keep the previous smaller pump as a backup for the smaller unit, or use it on a separate hydroponic application such as fertigation of a soilless propagation tray where a lower flow rate is appropriate.
• General hydroponic circulation: EZ Clone explicitly notes the Mag Drive pumps can be used in other hydroponic applications. At 1,100 GPH, the Mag 1125 has the capacity to circulate medium-sized reservoirs and to feed multi-port distribution manifolds for media-bed systems holding plants in fabric grow pots or larger containers.
• Aeroponic system retrofits and DIY builds: DIY aeroponic builders who need a known-good pump for a manifold-and-mister system at the same scale as the EZ-Clone Original 128-site can use the Mag 1125 as a specified component. The 4.65 lb weight and 8.63 in length fit standard 27-gallon reservoir totes used in DIY cloner builds.

EZ-Clone Mag 1125 vs Mag 925 and Other Mag Drive Sizes

The EZ Clone Mag Drive line includes four pump sizes — 450, 700/750, 925, and 1125 GPH. They share housing geometry, the same plastic-coated impeller approach, and the same limited lifetime warranty; what changes is the rated flow and the system size they are matched to.

Mag 1125 (this product, 1,100 GPH): Sized for the 128-site EZ-Clone Original. This is the highest-flow pump in the line. Choose this when your cloner is the 128-site model or when you specifically need 1,000+ GPH for a larger hydroponic application.

Mag 925 (925 GPH): Sized for the 64-site EZ-Clone Low Pro. This is the closest sibling and the most common point of confusion at purchase. The 925 and 1125 are visually similar; the manifold sizing in each cloner is the operational difference. If you have a 64-site Low Pro, the Mag 925 is the manufacturer-specified pump, not the 1125.

Mag 700 / 750 (700 GPH): The EZ Clone 750 is documented after extensive in-house testing as a viable replacement across the 32-site, 64-site, and 128-site EZ-Clone systems. It is the smallest pump rated for the 128-site by EZ Clone’s own testing; for production systems where peak misting pressure matters, the manifold-matched 1125 is the design specification and the 750 is the cross-compatible substitute.

Mag 450 (450 GPH): Entry-level pump in the line, sized for the smallest EZ-Clone cloners. Not appropriate for the 128-site system.

Versus third-party submersible pumps: Off-brand submersible pumps in the 1,000–1,200 GPH range are available at lower price points than the Mag 1125. The trade-offs are real: most third-party pumps in this range use shafted impellers with oil-lubricated motors (potential leak point), do not carry a lifetime warranty, and are not validated against the EZ-Clone manifold pressure curve. For a hobbyist building a one-off DIY cloner, a third-party pump may be acceptable; for replacement in an OEM EZ-Clone system, the cost of a clone-batch failure typically exceeds the price differential many times over.

Compatibility & Operating Range

The Mag 1125 is built for a specific EZ-Clone system and behaves consistently when used within that scope. The following parameters describe its compatibility envelope.

• Primary system compatibility: EZ-Clone Original 128-site aeroponic cloning system. This is the system the pump is sized to and where it ships from the factory.
• Cross-compatibility within EZ-Clone line: The Mag 1125 will operate in the 32-site and 64-site EZ-Clone systems as well, but the manifold and mister pattern in those smaller cloners is designed for lower flow. For replacement in a 32-site or 64-site, the manufacturer-recommended path is the Mag 750 (which EZ Clone has separately tested as a universal replacement across all three system sizes) or the size-matched 925.
• Hydroponic applications outside EZ-Clone: EZ Clone confirms the Mag Drive pumps can be used in other hydroponic applications. The 8.63 × 4.5 × 6.5 in form factor fits standard hydroponic reservoirs and DIY totes.
• Liquid type: Designed for water and water-based nutrient solutions. The plastic-coated impeller resists corrosion from standard hydroponic nutrients. Not rated for solvents, hydrocarbons, or industrial chemicals.
• Submersion: Submersible pump — must be fully covered by water during operation. Running the impeller in air, even briefly, will damage the pump. The adjustable filter sets a minimum effective water level; check that the inlet is fully submerged at the lowest expected reservoir level.
• Electrical: Wattage and voltage are not publicly listed by EZ Clone. For installation behind a timer, controller, or generator-backed circuit, request the electrical draw from EZ Clone support before commissioning. Standard EZ-Clone systems ship for 120V North American outlets.
• Reservoir maintenance pairing: Clean the adjustable filter as part of every reservoir change. If you are also storing nutrient stock or cleaning supplies in your propagation area, sealed-storage solutions such as Gamma seal lids keep reservoir top-off water and rinse solutions free of airborne debris between change cycles.

Usage Guidelines

The Mag 1125 is a plug-in submersible pump with no built-in timer, sensor, or controller. It runs continuously when powered and is intended to be operated according to the duty cycle of the EZ-Clone system controller it is installed in.

Operating mode in an EZ-Clone system: The pump is wired to operate continuously while the cloning chamber is in service, providing constant manifold pressure to the misters. The EZ-Clone Original 128-site does not cycle the pump; cycling is not the right operational pattern for aeroponic cloning of unrooted cuttings.

Filter maintenance: Inspect the adjustable inlet filter at every reservoir change — typically every 5–7 days during an active propagation cycle. The filter is what prevents biofilm fragments, root tips, and rockwool fibers from reaching the misters. Rinse under tap water, inspect for damage to the cage, and reseat before returning the pump to service.

Reservoir temperature: Because EZ Clone designs the Mag Drive pumps to minimize heat transfer into the water, the pump itself is not the primary heat source in the reservoir. If your reservoir is running warm, look first to ambient room temperature, light spill onto the chamber, and the volume of solution — not to the pump.

Warranty handling: The Mag 1125 carries EZ Clone’s limited lifetime warranty. Keep the original purchase receipt and the SKU label on the pump body; EZ Clone’s warranty process requires both for replacement claims. Pumps run dry, run in non-water liquids, or showing physical damage to the housing are not covered.

Storage between cycles: If the cloner will be idle for more than a few days, drain the reservoir, rinse the pump body and filter in clean water, and store the pump dry. Storing wet promotes biofilm growth inside the impeller chamber that can affect priming on the next start.

How to Install the EZ-Clone Mag 1125 Replacement Pump

Replacement installation is straightforward in an EZ-Clone Original 128-site system. The steps below cover the standard OEM replacement workflow.

1. Unplug and remove the failed pump. Disconnect the existing pump from the power outlet first. Open the EZ-Clone reservoir, disconnect the manifold supply line from the discharge port of the old pump, and lift the old pump out of the reservoir.
2. Inspect the new pump on arrival. Remove the Mag 1125 from its packaging. Confirm the housing is undamaged, the cord jacket is intact, and the adjustable filter is present and seated on the inlet. Confirm the discharge port is clear and the SKU label reads EZWP1125.
3. Attach the manifold supply line. Connect the existing EZ-Clone manifold supply line to the discharge port of the new pump. The Mag Drive pumps share discharge geometry across the line, so the existing tubing should fit without modification. If the prior pump was a different brand or model, verify hose ID and replace the tubing if needed.
4. Position the pump in the reservoir. Place the pump on the floor of the EZ-Clone reservoir, oriented so the inlet filter draws from open water and is not pressed against a wall or corner. The 8.63 in length fits the standard EZ-Clone 128-site reservoir without re-routing the manifold.
5. Set or adjust the inlet filter. The adjustable filter has an opening setting that determines how much water flow is restricted at the inlet. For a fresh, clean reservoir, the standard setting is appropriate; in a system that has been running with heavy biofilm, set the filter to its more open position and inspect more frequently.
6. Fill the reservoir and fully submerge the pump. Add cloning solution to the EZ-Clone reservoir to the standard fill line. Confirm the pump body and inlet filter are fully covered by water before applying power. Running the impeller dry, even briefly, will damage the pump and void the warranty.
7. Plug in and verify mister flow. Connect the pump cord to the EZ-Clone system outlet or power strip. Within a few seconds, the manifold should pressurize and the misters should produce an even spray pattern across all 128 sites. Walk the chamber and confirm flow at the stations farthest from the pump.
8. Watch the first 10 minutes of operation. Confirm there is no audible cavitation (a rattling sound from the pump body that indicates air ingestion), no leaks at the discharge connection, and that mister output is stable. Then close the reservoir and return the cloner to normal operation.
