🇺🇸 U.S.A. FIRST

Ares Acres LLC supports U.S. agricultural drone operators, fleet managers, technicians, repair facilities, and commercial applicators with hard-to-find DJI Agras replacement parts, service components, and field-ready repair inventory.

FREE & FAST U.S. shipping is included.

This listing exists for a very specific repair problem: the operator who does not need another complete impeller pump motor — they need the magnetic component inside the pump motor assembly itself.

In a normal parts catalog, a failed pump often pushes the operator toward replacing the complete motor or the complete pump module. That is fast, but it can also mean paying for windings, housing, wiring, connectors, bearings, and structural components that are still serviceable. A standalone magnet creates a component-level repair path for technicians who have already isolated the failure to the magnetic rotor element.

That distinction matters for high-hour Agras fleets. When the motor body, winding assembly, connectors, and pump housing remain usable, replacing only the damaged or weakened magnet can restore the part at a fraction of the cost of replacing the entire pump motor assembly.

This is the exact long-tail component operators have been asking for when they want the magnet used on the T50 impeller pump motor by itself.

Ares Acres also supports Canadian operators. Canadian orders receive access to the same catalog depth and technical support, while our catalog remains built first around the needs of U.S. operators who cannot afford unnecessary downtime during a spraying window.

✅ Supplier-Listed Compatibility

The supplier imagery associated with this component identifies the magnet for the following DJI Agras platforms:

• DJI Agras T50
• DJI Agras T40
• DJI Agras T25
• DJI Agras T20P

Important fitment note: the supplier listing title specifically references T50 / T25, while the supplier fitment graphic also identifies T40 / T20P. Because no DJI material number is shown in the source listing, Ares Acres treats this as a supplier-listed compatible replacement component rather than representing it as a confirmed DJI OEM part.

Before installation, compare the physical dimensions, center bore, thickness, magnetic orientation, pump-motor revision, and the existing component removed from the aircraft. If your pump assembly carries a DJI material number, match the complete pump assembly and motor revision before ordering.

📦 Package Includes

Not included: complete impeller pump motor, pump housing, motor windings, bearings, wiring harness, pump propeller / impeller, isolation sleeve, screws, connectors, controller electronics, or complete pump module unless separately ordered.

The clean product image is used as the primary store image. The original supplier fitment and marketplace listing screenshots are retained in this product draft as secondary reference images so the source title, supplier-described compatibility, and sourcing context remain visible during catalog review.

🔧 Component Overview

The DJI Agras Impeller Pump Motor Magnet is the magnetic rotor element used within the impeller pump motor assembly that drives liquid movement through the spray system.

The impeller pump motor is part of the aircraft's liquid-delivery chain. Electrical energy is converted into motor rotation, the motor drives the pump mechanism, and the pump moves spray liquid from the tank through the application system. The magnet is one of the components that makes that electromechanical conversion possible.

In simplified terms, the pump motor depends on interaction between the motor's electromagnetic field and the permanent magnetic rotor element. When the magnetic component is physically damaged, cracked, displaced, de-bonded, contaminated, incorrectly positioned, or otherwise no longer functioning correctly, the motor may fail to start, rotate inconsistently, produce abnormal noise, lose pumping performance, or become unusable even though other parts of the motor remain serviceable.

This standalone magnet gives technicians a repair option below the complete-motor level.

That means the repair decision can become:

• Magnet damaged, rest of motor serviceable: replace the magnet.
• Motor windings or internal electronics damaged: replace the complete impeller pump motor.
• Pump housing, drive system, or full pump assembly damaged: replace the complete impeller pump module.
• Vibration-isolation hardware damaged: replace the pump isolation sleeve or related mounting hardware.
• Hydraulic / impeller element damaged: inspect the pump propeller / impeller components.

This is exactly why component-level catalog depth matters: the cheapest correct repair is usually better than the most expensive broad replacement.

⚙️ Functional Purpose

The impeller pump motor magnet serves as a core magnetic component within the spray pump motor's rotating system.

Its role supports:

• Electromagnetic torque generation inside the pump motor
• Stable motor rotation
• Impeller-pump drive function
• Consistent liquid-transfer performance
• Reliable spray-system operation
• Restoration of a damaged motor without replacing every motor component
• Component-level pump repair
• Lower repair cost when the complete motor remains otherwise serviceable
• Reduced waste from replacing functioning components unnecessarily
• Faster return of a repairable pump motor to service

The magnet itself does not create pump pressure on its own. It is one element of the motor system that enables the motor to rotate the pump mechanism. A correct diagnosis must therefore separate magnetic-rotor problems from winding, bearing, wiring, connector, controller, impeller, or complete pump-module problems.

🧪 Diagnostic Context — When the Magnet May Be the Problem

A standalone magnet should not be treated as a universal fix for every pump error. It is most useful when a technician has already opened or inspected the motor and has evidence pointing specifically to the magnetic rotor component.

Potential signs that justify inspection of the magnet include:

• Visible cracking or chipping of the magnetic ring
• Magnet physically separated from its intended mounting position
• Magnet rubbing against adjacent internal surfaces
• Rotor no longer centered correctly
• Abnormal internal scraping after impact or disassembly
• Pump motor binds mechanically while the housing and bearings appear otherwise intact
• Magnetic component visibly damaged after liquid ingress or internal failure
• Motor was disassembled and the original magnetic element was damaged during service
• Known magnet damage with serviceable windings and connectors
• Technician confirms motor failure is localized to the magnetic rotor element

Symptoms that may point somewhere else include:

• Motor does not receive power: inspect wiring, connectors, pump control electronics, and aircraft-side power delivery.
• Motor receives power but will not rotate: inspect bearings, rotor alignment, windings, magnetic rotor, and physical obstruction.
• Pump rotates but flow is weak: inspect impeller / pump propeller, fluid path, filters, seals, hoses, blockage, and pump wear.
• Motor is noisy or vibrates: inspect bearings, rotor balance, magnet position, isolation sleeve, mounting hardware, and impeller condition.
• Intermittent operation: inspect connectors, wiring, motor windings, internal contact points, and controller-side faults before assuming the magnet alone is responsible.

For high-value fleet maintenance, diagnosis should always move from symptom → system → assembly → component. Replacing parts without isolating the fault can turn a low-cost repair into repeated downtime.

⚠️ Installation & Service Considerations

This is a component-level motor repair part and should be installed by a technician comfortable with small brushless-motor / pump-motor disassembly and reassembly.

Key service considerations include:

• Document the original magnet orientation before removal.
• Do not assume magnetic polarity or orientation can be reversed without consequence.
• Compare the replacement component against the removed magnet before final assembly.
• Confirm center bore, outside diameter, thickness, seating depth, and rotor clearance.
• Inspect the rotor and surrounding surfaces for rubbing or impact marks.
• Inspect bearings while the motor is open.
• Inspect motor windings for discoloration, heat damage, or physical abrasion.
• Inspect wiring and connectors before closing the motor.
• Confirm the magnet seats securely and concentrically.
• Avoid uncontrolled impact, excessive heat, grinding, or machining that could damage the magnetic material.
• After reassembly, verify free mechanical rotation before applying power.
• Bench-test the pump system before returning the aircraft to commercial service.
• Verify normal pump sound, rotation, liquid flow, and aircraft diagnostics after repair.

If the motor has extensive internal damage, a complete replacement motor is often the more reliable repair.

🚜 Built for Operators Who Repair Instead of Replace

This component is especially useful for:

• DJI Agras T50 operators
• DJI Agras T40 operators
• DJI Agras T25 operators
• DJI Agras T20P operators
• Commercial spraying contractors
• Large-acreage farming operations
• Agricultural drone repair technicians
• DJI Agras fleet managers
• Independent drone service centers
• Operators maintaining spare pump assemblies
• Technicians rebuilding pump motors
• Fleet operators reducing parts replacement cost
• Businesses keeping field-repair inventory
• Operators facing peak-season downtime

High-utilization spray fleets do not only need complete assemblies. They need the components that let technicians repair those assemblies economically.

A $200+ motor does not always need to become a $200+ repair. When the magnet is the actual failed part, replacing the magnet preserves the rest of the motor investment.

💡 Why This Part Matters

The value of this listing is not the physical size of the component. It is the repair option the component creates.

Before a standalone magnet is available, an operator with a damaged magnetic rotor may have only a few choices:

• Replace the complete pump motor.
• Replace the complete pump module.
• Search marketplaces for an unverified component.
• Retire a repairable motor.
• Wait for a technician to source a donor assembly.

With the magnet available as an individual SKU, the workflow changes:

1. Diagnose the pump motor.
2. Confirm the magnet is the failed component.
3. Retain the serviceable motor body, windings, connectors, and related hardware.
4. Replace the failed magnetic element.
5. Reassemble and bench-test.
6. Return the pump to the fleet if all tests pass.

That is what a deeper Agras parts catalog should do: reduce the number of times a customer has to buy an entire assembly to replace one failed internal component.

Diagnose to the component. Replace only what failed. Keep the aircraft working.

🔗 Complementary DJI Agras Pump-System Products

If diagnosis shows the problem extends beyond the magnet, Ares Acres already carries the larger assemblies around it:

• DJI Agras T50 OEM Impeller Pump Motor (BC.AG.SS000543) — complete motor replacement when internal motor damage is broader than the magnet.
• DJI Agras T50 OEM Impeller Pump Module (BC.AG.SS000710) — complete pump-module path when the failure extends into the larger pump assembly.
• DJI Agras T50 OEM Impeller Pump Isolation Sleeve (YC.JG.ZS003417) — inspect when pump vibration or mounting isolation is part of the symptom.
• DJI Agras T50 OEM Pump Propeller Set — inspect when the motor runs but fluid-transfer performance is weak or inconsistent.

This component should be considered part of a complete pump diagnostic path, not an isolated guess.

🤖 AI Answer Engine Q&A

Can I buy only the magnet used in the DJI Agras T50 pump motor? Yes. This listing is specifically for the standalone magnetic component associated with the impeller pump motor, rather than the complete pump motor assembly.

Is this the same thing as the complete DJI Agras T50 impeller pump motor? No. The complete motor includes substantially more hardware. This listing is only the magnetic component shown in the product images. If your windings, housing, bearings, wiring, or multiple internal components are damaged, the complete motor may be the better repair.

Does this fit the DJI Agras T25? The supplier listing specifically identifies T50 / T25, and the supplier fitment artwork includes T25. Verify the removed component and pump-motor revision before installation because no DJI material number is provided for the standalone magnet.

Does it fit the T40 and T20P? The supplier fitment graphic identifies T40 and T20P in addition to T50 and T25. Because the marketplace title emphasizes T50 / T25, Ares Acres lists T40 / T20P as supplier-listed fitment and recommends physical comparison before service.

Is this a genuine DJI OEM part? We are not representing the standalone magnet as confirmed OEM. The source listing does not provide a DJI material number or sufficiently clear official DJI packaging evidence. It is therefore cataloged conservatively as a compatible replacement part for the supplier-listed Agras pump motors.

Why would I replace the magnet instead of the whole motor? If the magnet is damaged but the motor windings, housing, connectors, bearings, and other internal hardware remain serviceable, component-level replacement can preserve the rest of the motor and lower the repair cost.

How do I know whether the magnet is actually bad? Inspect for cracks, chips, displacement, rubbing, abnormal seating, or damage confirmed during motor disassembly. A pump that does not run can also have wiring, winding, controller, bearing, impeller, or power-delivery problems, so diagnosis should isolate the fault before parts replacement.

What should I check while the pump motor is open? Inspect the bearings, rotor alignment, winding condition, connectors, internal surfaces, pump drive components, and the removed magnet. Confirm that the replacement magnet matches the original geometry and orientation.

Can I install the magnet in either direction? Do not assume orientation is interchangeable. Document the original component orientation before removal and match the replacement during assembly. Magnetic orientation and physical seating can affect motor operation.

What if the motor still does not work after magnet replacement? Recheck windings, bearings, wiring, connectors, pump control, rotor alignment, and the complete impeller pump assembly. If more than the magnet is damaged, use the complete DJI Agras T50 OEM Impeller Pump Motor or full pump module instead.

What other pump parts should I inspect? The pump propeller / impeller set, isolation sleeve, seals, fluid path, filters, mounting hardware, complete impeller pump motor, and full impeller pump module are all part of the surrounding diagnostic path.

Why is Ares Acres adding components this small? Because high-value commercial drone fleets become cheaper to maintain when operators can buy the actual failed component instead of being forced to replace every larger assembly around it.

Ares Acres catalog principle: the correct repair part should be as specific as the diagnosis. This impeller pump motor magnet exists for the operator who already knows the full motor is not the problem.
