The fastest way to order the wrong pump-related part is to describe the problem only by symptom. A T100 that loses spray pressure, pulses unevenly, or comes back from a hard workday with a wet pump bay may look like it needs "a pump." In a real repair room, that is not enough. The impeller pump assembly is made up of multiple replaceable items, and the useful question is narrower: which visible part, connector, seal, housing, line, or related fitting matches the material number on the product record?

This guide is for repair teams, fleet managers, and dealers who need a repeatable way to identify DJI AGRAS T100 impeller pump assembly parts before placing an order. It uses the UNITED UAV T100 impeller pump assembly product page as the ordering reference and keeps the work centered on material-number verification instead of guesswork.

Start With the Product Record, Not a Nickname

The product record for DJI Agras T100 Impeller Pump Assembly Parts & Accessories lists the replacement component group and its material-number set. For this article, the verified catalog evidence shows 20 material-number entries and 16 available variants for the product page. That does not mean every symptom needs all 16 parts. It means the page should be treated as the reference shelf for this pump assembly group.

Experienced technicians usually avoid starting with a casual part name. "Pump fitting," "small seal," or "that black piece near the hose" can mean different things to different people. A better habit is to start with the part location, confirm the shape against the numbered product image, and then match the material number. The material number is the stable ordering language.

Material Numbers to Check

Use the product page and source image to verify the exact component before ordering. The verified product evidence for this T100 impeller pump assembly group includes:

BC.AG.SS001032, BC.AG.SS001033, YC.JG.FM000157, YC.JG.MY001052, YC.JG.MY001052-1, YC.JG.MY001053, YC.JG.MY001053-1, YC.JG.MY001315, YC.JG.MY001327, YC.JG.MY001828, YC.JG.MY001830, YC.JG.ZS002233, YC.JG.ZS002233-3, YC.JG.ZS006166, YC.JG.ZS006167, YC.JG.ZS006175, YC.ST.LL000717, YC.WJ.L01234, YC.WJ.L01234-7, and YC.XC.XX001409.

If your removed part has a readable label or packaging code, compare that code first. If the code is not readable, use the numbered product image and the physical part shape. Do not substitute a visually similar item from a different assembly unless a human parts reviewer confirms it.

A Practical Identification Workflow

1. Clean and photograph before disassembly gets messy

Before separating parts, wipe enough residue away to see edges, fittings, screw points, and hose connections. Take one wide photo of the pump area and one close photo of the part you think needs replacement. A good repair photo includes the surrounding parts, not only the broken item. This makes it easier to confirm where the component sits in the assembly.

An old shop habit is worth keeping: photograph the part while it is still installed, then photograph it again after removal. The first photo shows position. The second photo shows shape. Together they reduce the chance that a buyer orders the right-looking item from the wrong location.

2. Separate symptom diagnosis from part identification

Pressure loss does not automatically prove that the impeller pump assembly is the only source of the issue. Hoses, fittings, metering components, contamination, and installation errors can create similar field symptoms. This article is not a troubleshooting manual for the aircraft. It is an ordering workflow for the impeller pump assembly product group.

For ordering, write down the part you can actually identify. If the team cannot identify a visible component, hold the order until someone compares the source product image and material-number list. Rushing this step is how small parts become repeat orders.

3. Match by location, silhouette, and material number

Use three checks together. First, confirm the location in the pump assembly area. Second, compare the silhouette, fastener pattern, connector shape, or hose relationship against the product image. Third, match the material number. A match on only one of the three checks is weak. A match on all three is much stronger.

Teams that service several AGRAS models should be especially strict here. Similar-looking components can sit in different systems or belong to different model groups. Keep the T100 impeller pump assembly page open while checking the part. Do not rely on a memory from a T40, T50, T30, or older repair.

What to Record Before Ordering

Create a small ordering note for each part. The note should include the drone model, the product page URL, the material number, the observed failure or replacement reason, and the source image reference. Add the aircraft serial or fleet unit ID if your internal process requires it.

A repair center can also add a confidence level:

• High confidence: material number is readable and matches the product record.
• Medium confidence: shape and position match the numbered image, but the code is unreadable.
• Low confidence: only the symptom is known, and the physical part has not been confirmed.

Only high and well-reviewed medium confidence orders should move forward. Low confidence parts should go back to inspection.

Build a Two-Bin Parts Decision

For pump assembly work, it helps to separate parts into two bins before the buyer sees the order. The first bin is "identified parts." These have a matching material number, a clear product page reference, and a photo that shows the component well enough for another person to confirm the match. The second bin is "suspected parts." These may be related to the symptom, but the part has not been matched with enough evidence.

Do not mix the two bins in the same order note. Identified parts can move toward purchase review. Suspected parts should stay in the inspection workflow. This simple separation prevents the common situation where one known item and two guesses are bundled together, then the whole order feels more certain than it really is.

For the T100 impeller pump assembly group, the two-bin method is especially useful because pump-area symptoms can involve nearby fluid handling components. A wet area, uneven flow, or visible residue may be real evidence, but it is still not a material number. The buyer needs to know which part is confirmed and which observation still needs inspection.

How to Use Photos With the Product Image

When you compare the removed component to the UNITED UAV product image, do not crop the photo too tightly. A tight photo can hide scale, connector orientation, and the relationship between small parts. Use one wider bench photo, then one close image of the material number or distinctive shape. If the part is dirty, take a photo before cleaning and after cleaning. The before photo can explain residue or field condition, while the after photo helps with identification.

If the team sends photos by phone, name each image before forwarding it to the buyer. A file name such as T100-unit-7-pump-area-suspected-YC-JG-FM000157.jpg is much more useful than a random camera number. Good file names do not prove the part is correct, but they keep the review from becoming a guessing exercise.

Field Lessons for Pump Assembly Orders

The experienced mistake is ordering from the symptom. The experienced fix is ordering from evidence. When a pilot says, "the pump is weak," that is the start of the inspection, not the part number. Ask what changed, whether the issue appeared after cleaning, whether a hose or fitting was disturbed, and whether any part shows impact, swelling, residue, stripped fasteners, or cracked housing.

Another useful habit is to keep the removed part in a labeled tray until the replacement arrives. Do not throw the part away after taking a photo. When the new component lands on the bench, compare old and new before installation. If the team ordered the wrong item, this catches the error before the aircraft is opened again.

For seasonal fleets, the best time to check pump assembly parts is before the high-volume spray window. A rushed in-season order often lacks photos, lacks a material number, and depends on memory. A preseason bench check gives the team enough time to compare the product page, confirm the replacement component, and group small items into one controlled order.

FAQ

How do I identify DJI AGRAS T100 impeller pump assembly parts if the label is unreadable?

Use the source product image, the part location, and the shape of the component together. If the material number cannot be read, do not order from the symptom alone. Have a parts reviewer compare the removed component against the numbered product image before ordering.

Can I use a similar-looking part from another AGRAS model?

Do not assume interchangeability. This article only supports ordering against the T100 impeller pump assembly product page and its listed material numbers. A different model page should be checked separately.

Should I replace the whole pump assembly when one item is damaged?

Not automatically. The right scope depends on the visible damage, diagnosis, and material-number match. This guide is for identifying orderable parts, not for making a repair decision for every aircraft condition.

Why are material numbers important?

Material numbers reduce ambiguity. They let the repair team, buyer, and supplier talk about the same component without relying on informal names.

What should I send to a parts reviewer?

Send the product page URL, a clear installed photo, a removed-part photo, the suspected material number, and a short description of the observed issue.
