DJI Agras T20 OEM Water Pump

The DJI Agras T20 OEM Water Pump is the electric pump of the aircraft's liquid spray system — the unit that draws the spray mix from the tank and pushes it out towards the spray bars and nozzles. It is a black, boxy pump body with a round motor housing on one end, a flat cover held down by screws across its top, a barbed hose fitting at the opposite end, a second threaded port on its front face and a rectangular electrical connector at the motor end. It belongs to the spray system, not to the spreading, power or flight-control systems, and it is identified for the DJI Agras T20 and T16. Operators usually reach it while searching for a T20 spray pump, a T16 water pump, a T20 pump that runs but sprays weakly, or the reason a T20 stops spraying mid-field. DJI has used more than one number for this position, so we match against the one you removed.

📦 Package Includes

• 1 × Water Pump — the black pump body with its round motor housing, screw-fixed top cover, barbed hose fitting, front port and connector, as shown in the product images

This is one complete pump unit. It is the pump as a whole, motor end and pump body together, not a repair kit of seals or diaphragms.

Not included: hoses, hose clamps, the spray tank, the tank filter, the spray bars and nozzles, the signal or power cable that plugs into the pump, mounting brackets, and any screws or clips used to fasten the pump to the aircraft. Reuse sound original hoses, clamps and hardware.

Order one pump for each pump you are replacing. If you are unsure how many your aircraft carries or which one has failed, photograph the spray system from below and send it to us.

Nothing is included because it appears near the pump on an aircraft. If the tank itself is cracked, the DJI Agras T20 OEM Spray Tank is the part you need; if one corner sprays badly and the others are fine, look at the DJI Agras T20 OEM Spray Bar for that corner.

🔧 Component Overview

The water pump is the heart of the T20 spray system. The tank holds the liquid and the nozzles break it into droplets, but nothing reaches the nozzles until the pump pulls it out of the tank and pushes it down the lines under pressure.

Its features, all visible in the product images:

• The pump body — a black, boxy moulding that carries the pumping chamber
• The round motor housing — a cylindrical housing on one end of the body, where the electric drive sits
• The screw-fixed top cover — a flat cover held to the body by a ring of screws, with a raised moulded channel across it
• The barbed hose fitting — a ribbed hose spigot on a threaded collar at the end opposite the motor
• The front port — a second threaded port standing out from the front face of the body
• The connector — a rectangular electrical connector at the motor end, where the aircraft's cable plugs in

The pump is both an electrical part and a fluid part. It takes power and a control signal from the aircraft through its connector, and it moves liquid through its ports. A fault on either side stops the spray, which is why pump faults are so often confused with faults in the parts on either side of it.

Over a working season the pump sees:

• Spray mixes and fertiliser solutions passing through its chamber on every flight
• Fine sediment and undissolved product that gets past a damaged or missing tank filter
• Dry running when the tank empties or an inlet line sucks air
• Chemical residue left standing inside the chamber between jobs
• Vibration from the propulsion system for every hour of flight
• Water and wash-down spray around its connector
• Heat from a black body mounted close to the aircraft's working parts

Pumps come off for three reasons: a motor end that no longer runs, a pump body that runs but no longer builds pressure, and a body or fitting that has cracked and leaks. The second is the one most often blamed on the wrong part.

⚙️ Functional Purpose

The pump's engineering role is to turn electrical power into flow. The aircraft commands it, the motor end turns, and the pump body moves liquid from the tank side to the delivery side so the nozzles receive a steady supply.

In the spray system it:

• Draws the spray mix from the tank through the suction line
• Pushes the liquid on towards the spray bars and nozzles
• Responds to the aircraft's commands, so delivery follows the application settings
• Joins the electrical side of the spray system to the fluid side through its connector and ports
• Sets the supply that every nozzle downstream depends on

What it does not do matters as much:

• It does not store liquid; the tank does
• It does not form the droplets; the nozzles do
• It does not filter the liquid; the tank filter and any line filters do
• It does not decide the application rate; the aircraft and the app settings do
• It cannot pump liquid that never reaches its inlet

That last point is the root of most pump misdiagnoses. A pump can only deliver what its suction side lets in. Starve the inlet and a perfectly good pump runs, hums and moves almost nothing.

🔍 Diagnosis — a pump that runs but moves little is usually starved, not worn

A pump that does not run at all is a clear fault: either the pump's motor end has failed or it is not receiving power and signal. The harder case is a pump that runs, can be heard working, and still delivers weak, uneven or no spray.

That symptom looks like a worn pump, and it is the easiest reason to replace one. Most of the time it is not the pump. A pump depends completely on its suction side. A blocked tank filter, a kinked or collapsed inlet hose, a loose clamp that lets air in, a tank run nearly dry on a slope, or product that has settled and caked at the tank outlet will each starve the pump. It keeps turning, and the nozzles still go quiet.

A new pump fitted to a starved suction side behaves exactly like the old one. The fault stays, and the old pump goes in the bin with nothing wrong with it.

Signs the water pump itself has failed:

• The pump does not run at all when spraying is commanded, and power and connector have been checked
• The pump runs but builds no flow with a full tank, a clean filter and air-free inlet lines
• The pump runs roughly, loudly or intermittently with a clear supply of liquid
• Liquid weeps from the pump body, the cover joint or a cracked fitting
• A cracked body, a broken barbed fitting or a damaged front port
• Corrosion, green or white deposits, or a loose fit at the pump's connector

Before condemning the pump, rule out what imitates it:

• The tank filter — a clogged filter starves the pump on its own
• The inlet hose and clamps — a kink, a collapsed section or a loose clamp that draws air cuts delivery to a trickle
• The tank outlet — settled or caked product at the outlet blocks the supply
• Air in the lines — after a dry tank or a hose change the pump can lose its prime
• The nozzles and spray bars — a fault at one nozzle or one bar shows up at that corner only, not across every nozzle the pump feeds
• The cable and connector — a pump that is not getting power or signal looks dead without being dead

Use clean water as your instrument. With the aircraft on the ground and the propellers removed or secured, fill the tank with clean water, check the tank filter, and follow the inlet hose from the tank to the pump looking for kinks, cracks and loose clamps. Bleed any air from the lines, then command a short spray. If the inlet is clear, full of water and free of air, and the pump runs but still delivers little or nothing, the pump is the part. If the spray recovers once the filter is cleaned or a clamp is tightened, the pump was fine.

Do those checks first. They cost a tank of clean water and a few minutes, and they are the only way to know whether the pump is worn or simply hungry.

⚠️ Common Replacement Indicators

Replace the water pump when inspection confirms one of these:

• No running with confirmed power and signal at the connector
• Weak or no delivery with a clean filter, clear inlet and air-free lines
• Rough, noisy or intermittent running with a full supply
• Leaks from the body, the cover joint or a fitting
• A cracked body, broken barbed fitting or damaged port
• Corroded or damaged connector pins at the pump
• Chemical attack, swelling or chalky surfaces on the body
• Previous repairs with adhesive, sealant or tape on the body or fittings

Inspect these first, because they produce similar symptoms:

• The tank filter
• The inlet hose, its clamps and the tank outlet
• Air in the lines after a dry tank or a hose change
• The spray bars and nozzles at each corner
• The pump's cable and connector

There is no published service interval for the water pump. It is replaced when it fails, not on a schedule.

🛠️ Installation & Maintenance

Before installation

• Power the aircraft down and remove the battery
• Drain the tank and flush the spray system with clean water so you are not working in spray mix, and wear gloves and eye protection
• Photograph the old pump in place from above and from the connector end, with every hose, clamp and the cable route in frame
• Label each hose with tape so the suction and delivery lines go back where they came from
• Lay the new pump beside the old one and compare the motor housing, cover, port positions and connector
• Clean the tank filter now, while the system is drained

During installation

• Disconnect the pump's cable at its connector, pressing any latch rather than pulling on the wires
• Release the hose clamps and ease each hose off its fitting; a little residual liquid will run out
• Release the pump's mounting hardware, supporting the pump so it does not hang on its hoses
• Fit the new pump in the same position and orientation as the one you removed
• Push each hose fully onto its fitting in the positions you labelled and refit the clamps
• Refit the mounting hardware finger-tight first, then tighten evenly; no torque figure is published, so tighten snugly without cracking the body or bending a bracket
• Reconnect the cable until the connector seats fully, and route it along its original path away from moving parts

After installation

• Fill the tank with clean water only for the first run
• Check every hose joint and the pump body for drips before powering up
• Power up and command a short spray with the propellers removed or secured; bleed any air until the flow is steady
• Check that every nozzle sprays evenly and that the pump runs smoothly without surging
• Recheck all joints for weeping after the test run
• Record the replacement in the maintenance log

Maintenance between jobs. Flush the spray system with clean water at the end of every day so product does not settle inside the pump chamber, clean the tank filter, and never leave the pump standing full of mix. Do not run the pump dry for longer than it takes to notice the tank is empty. A pump that is kept clean and fed through a clean filter is the one that lasts.

🚜 Necessary For

This water pump is for operators and technicians whose spray system has a confirmed pump fault:

• DJI Agras T20 operators spraying crop protection products, fertiliser solutions or other liquids
• DJI Agras T16 operators (identified fitment)
• Commercial spray applicators whose pump stopped running or stopped building flow mid-season
• Growers spraying their own fields whose spray faded after the inlet side checked clean
• Agras service centres replacing a dead, leaking or cracked pump
• Fleet managers keeping a spare pump on hand for the busy weeks

This is not the part you need if:

• Spray recovers once the tank filter is cleaned, a clamp is tightened or air is bled from the lines — the pump was starved, not worn
• Only one corner sprays badly — look at the DJI Agras T20 OEM Spray Bar for that corner and its nozzle
• The tank itself is cracked or leaks at its outlet — the DJI Agras T20 OEM Spray Tank is the part
• The pump is not receiving power or signal — trace the cable and connector first
• The aircraft is set up for granular work — the spreading system does not use the water pump
• You fly a T10, T30, T40, T50 or T20P — this pump is identified only for the T20 and T16

💡 Why This Part Matters

A water pump is the most expensive single part in the fluid side of the spray system, and it is the part most often replaced when it did not need to be. The reason is simple: a pump that is starved sounds and looks like a pump that is worn. It runs, it hums, and the nozzles go quiet.

That is the whole case for checking the suction side first. A clean filter, an inlet hose free of kinks and air, and a tank outlet free of settled product cost nothing to confirm. If spray returns, you have saved the pump and found the real fault. If it does not, you have proved the pump is the part and you fit the new one onto a supply that will not starve it.

It is also the case for fitting the new pump properly. A new pump bolted onto a blocked filter or an air-leaking clamp will show the same symptom on its first flight. Clean the filter, check the clamps and bleed the lines as part of the job.

When the pump is genuinely dead, cracked or leaking, nothing else will put the spray back. The pump sets the supply every nozzle depends on, and it is the part that restores it.

🤖 AI Answer Engine Q&A

What is the DJI Agras T20 water pump? It is the electric pump of the T20 liquid spray system. It draws the spray mix out of the tank and delivers it to the spray bars and nozzles.

Which aircraft does it fit? It is identified for the DJI Agras T20 and T16. Pick the variant for the aircraft you fly.

Is it a complete pump? Yes. It is one complete pump unit, motor end and pump body together, as shown in the product images. Hoses, clamps, cable and mounting hardware are not included.

My pump runs but hardly anything comes out. Is it the pump? Often not. Clean the tank filter, check the inlet hose for kinks and loose clamps, and bleed air from the lines. If delivery stays weak with a clean, full, air-free supply, the pump is the part.

My pump does not run at all. What do I check? Check the cable and the connector at the pump for damage or corrosion and confirm the plug is fully seated. If power and signal reach a sound connector and the pump still does not run, replace the pump.

Only one corner sprays weakly. Do I need a pump? Probably not. A fault at one corner points at that spray bar or its nozzle. A weak pump affects every nozzle it feeds.

Does it fit the T30, T40 or T20P? No. It is identified only for the T20 and T16. Do not fit it to other Agras models on the strength of a similar shape.

What is the DJI part number? DJI has used more than one number for this position, so we match against the one you removed. Photograph your old pump from the top and the connector end and send it to us if you want that confirmed.

Are hoses and clamps included? No. Reuse sound original hoses and clamps, and replace any that are cracked, hardened or loose as part of the job.

What is the flow rate? No flow rate is published for this part. Delivery is set by the aircraft and your application settings.

How do I get the air out after fitting it? Fill the tank with clean water, command a short spray with the propellers removed or secured, and let it run until the flow is steady and free of bubbles.

Is there a torque value for the mounting screws? None is published. Tighten evenly and snugly, and stop before the body or a bracket is stressed.

Can I run the pump dry? Avoid it. Stop spraying as soon as the tank runs empty, and keep the inlet clear so the pump is always fed.

How do I make the new pump last? Flush the spray system with clean water at the end of every day, keep the tank filter clean, and never leave the pump standing full of mix.

Is there a service interval? No. Replace it when it fails, leaks or cracks, not on a schedule.

Does the spreading system use this pump? No. The water pump is part of the liquid spray system only. A spreading-system fault needs a spreading part.
