🔧 Component Overview

DJI Agras T40 Water Pump Assembly | Complete spray pump unit with signal connection for agricultural liquid-delivery service

The Water Pump Assembly is what makes the spray system a pressure circuit rather than a tank of liquid. Rate, pattern and coverage on DJI Agras T40 all depend on it holding pressure steadily while the aircraft asks for more and less of it through a pass.

It runs wet, under load, for most of a flight. That duty cycle is what makes a pump a service item on an agricultural airframe rather than a fit-and-forget component. That is the job the Water Pump Assembly does on DJI Agras T40.

• Attached electrical and signal cable assembly shown with the pump
• Integrated pump housing and hose interfaces
• Moves spray liquid from the tank toward the nozzles
• Interfaces with the aircraft's spray-control electronics
• Interface with aircraft signal and power connections
• Pump does not run
• Weak or inconsistent spray output
• Pump leakage
• Spray-system fault after pump diagnosis
• Internal impeller or motor failure
• Confirmed pump failure during bench testing

⚙️ Functional Purpose

Comparing the existing part carefully for shape, connector style, mounting points, hose or cable routing, left/right orientation where applicable, and any visible material or part number is all it takes, and this listing is picked and packed against exactly that.

On DJI Agras T40, the water pump assembly has one job, and the rest of the assembly is built on the assumption that it is doing it. That is what makes a fault here feel larger than the part: the components around it have no fallback and no way to report its absence directly.

A weak Water Pump Assembly does not stop the job, it changes it: the same pass goes out at a lower rate than it was quoted at, and nothing on DJI Agras T40 reports that.

What the water pump assembly is there to do on DJI Agras T40:

• Supports commanded spray flow
• Maintains pressure and flow through the liquid system
• Supports repeat start-stop spray cycles
• Restore spray-flow capability
• Support stable liquid delivery
• Maintain repeatable application output
• Reduce downtime caused by a failed pump module

🩺 Symptoms & What They Usually Mean

These are the observations that bring pilots to a water pump assembly. Each line gives what you see, what it usually means, and the quickest way to tell.

• Pressure will not come up — usually a worn wet end, or a restriction at the inlet. On DJI Agras T40, check the inlet and screen before condemning the pump.
• Rate drifts through a pass — usually opening impeller clearances. Test against clean water and watch the pressure ceiling, then re-test on DJI Agras T40.
• Liquid weeping at the drive end — usually the drive-end seal. On DJI Agras T40, act on it before it reaches the motor.
• Pump runs hot — usually working against a restriction. Feel the body after a run and compare, then re-test on DJI Agras T40.
• A weep or drip that only appears under load — usually a crack or a distorted sealing face. On DJI Agras T40, wipe it dry, run it, and look for where it starts.

Work the cheap checks first and the picture usually resolves itself. Where it points at the water pump assembly, this listing is the part, and the Exact-Fit Guarantee covers the match.

⚠️ Common Replacement Indicators

Chemical and grit wear the wet end. Impeller clearances open up, seals harden, and the Water Pump Assembly goes on running while delivering less pressure than the controller believes it is. On DJI Agras T40, that is how a Water Pump Assembly usually reaches the end of its life.

Dry running is the quick way to end one. A pump asked to work with an empty tank or a blocked inlet loses its seal faces in minutes, so on DJI Agras T40 a run-dry event is worth treating as a service event. It is one of the wear patterns to expect at the Water Pump Assembly on DJI Agras T40.

The seal at the drive end is the usual leak. Liquid tracking toward the motor is the signal to act, because what follows is an electrical failure rather than a hydraulic one. On DJI Agras T40 that is worth knowing about before it happens.

A pump body is a pressure vessel as well as a mounting. A hairline at a boss or a sealing face holds while the system is cold and weeps once DJI Agras T40 is working, which is why a leak that appears only under load is worth taking seriously. It is one of the ways a Water Pump Assembly on DJI Agras T40 comes to be replaced.

Pressure that will not come up, a rate that drifts through a pass, an audible change in pump note, liquid weeping at the drive end, or a pump that runs hot — on DJI Agras T40 those point at the Water Pump Assembly or at a restriction in the circuit it is working against.

What pilots usually find when they come to a water pump assembly:

• Abnormal pump noise
• Intermittent operation
• Electrical connector damage

🧰 Fitment At A Glance

Everything that identifies this part, in one place.

• Aircraft: DJI Agras T40
• Assembly: Spray System Parts
• Condition: New aftermarket replacement component
• Supplied as a set: the package list above states exactly what is included.

Model, installed position and connector or mounting geometry are what identify a water pump assembly for DJI Agras T40, and all three are stated above. The Exact-Fit Guarantee carries the rest, so this is a short list to glance at rather than a checklist to clear.

---

🛠️ Installation & Handling Notes

Prime, leak-check, and function-test the liquid system after installation. Confirm hose routing, electrical connectors, seals, and pump direction before field use.

Flush the circuit before fitting. Grit left in the lines reaches the new Water Pump Assembly the first time DJI Agras T40 builds pressure, which is the most common reason a fresh pump behaves like a worn one.

Prime it before the first run and never let it run dry on the bench. Seal faces are the part of a pump that does not forgive. On DJI Agras T40, getting this right is what makes the Water Pump Assembly last.

Support the plumbing so the Water Pump Assembly is not carrying hose loads. Strain at the ports works the seal and shortens the life of an otherwise good pump. It is the step that makes the difference on DJI Agras T40.

Run clean water through at working pressure and check every joint dry before chemical goes anywhere near it. On DJI Agras T40 the Water Pump Assembly rewards the extra minute here.

Bring the fasteners up evenly and in sequence. A pump body drawn down unevenly distorts its sealing face, and on DJI Agras T40 that is a leak you will be back for. That applies every time a Water Pump Assembly goes back into DJI Agras T40.

Worth checking while the assembly is open and once the water pump assembly is in:

• Power the aircraft down completely before service.
• Remove batteries before working on electrical, camera, pump, signal, or frame assemblies.
• Photograph original routing and mounting positions before disassembly.
• Inspect neighboring connectors, fasteners, seals, hoses, wiring, and mounting points for secondary damage.
• Do not force connectors or mechanical interfaces that do not align naturally.
• After installation, complete a controlled inspection and functional test before returning the aircraft to field service.

Finish the same way whatever the job involved: reassemble fully, power up on the ground, run any calibration DJI Agras T40 offers for the affected system, and fly a low controlled test before the repair goes back to work.

💡 Tips From The Workshop

Things that make a water pump assembly job go smoothly, from people who do it often:

• Flush the circuit before fitting; the grit that ended the last pump is still in the lines.
• Never run it dry, even on the bench.
• Test against clean water and watch pressure, not just flow.
• Support the plumbing so the pump is not carrying hose loads.

---

🔗 Worth Having On Hand

Whatever wore the water pump assembly usually left marks nearby, and the labor of reaching this area is most of the job. While the assembly is open, these are the parts people reach for:

• The seals and screens either side of it
• A spare filter screen
• The hoses that carried the debris that ended the last one
• Anything on DJI Agras T40 showing a witness mark from the same impact

We stock all of it and can ship it together, which saves a second shipping cycle and a second teardown.

---

♻️ Service Life, Handling & Stocking

The seals, screens and hoses on either side, since the circuit is open and the debris that ended the last pump is still in it. The labor is already spent once DJI Agras T40 is open for the Water Pump Assembly.

Store spares in their packaging, out of direct sun and heat, and keep small parts labeled — a water pump assembly you cannot identify with certainty on the shelf is not really a spare.

Having the part on the shelf turns a week of waiting into an afternoon of work, which is most of the argument for keeping one.

---

🔎 Telling Similar Parts Apart

Pumps for DJI Agras T40 differ in displacement, port size, voltage and mounting, and a visually similar unit from another model will fit the bracket while delivering a different rate. Matching the Water Pump Assembly you removed from DJI Agras T40 is the shortcut, and it is in your hand already.

If the part you removed carries a number, a marking or a molded-in identifier, that is the fastest route. Where it does not, geometry does the job: hole spacing, connector type and count, orientation, and how it sits against its neighbors — all of which this listing states.
