{"product_id":"dji-agras-t30-oem-pump-plunger-base","title":"DJI Agras T30 OEM Pump Plunger Base","description":"\u003cp\u003eThe DJI Agras T30 OEM Pump Plunger Base is a single plunger from the spray pump of the DJI Agras T30 and T10. As shown in the product images, it is a bright, polished cylindrical shank with a black ribbed flange at one end — the base end — and a plain, rounded tip at the other. In a plunger pump, the plunger is the moving part that displaces the liquid on every stroke, and its polished surface is the surface the pump seal runs on. This part is that plunger, not the pump body, not the pump motor and not a seal. One plunger base is supplied per unit. It is identified for the DJI Agras T30 and T10. Operators usually reach it while searching for a T30 pump plunger, a T30 plunger pump repair part, a T10 pump plunger base, a T30 pump that runs but has lost pressure, or a T30 pump leaking at its seal. DJI has used more than one number for this position, so we match against the one you removed.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🇺🇸 U.S.A.

A plunger pump works by driving a smooth plunger back and forth through a seal: each stroke draws liquid in through one valve and pushes it out through another. The plunger is the part that moves, and its finish is what the seal depends on.\u003c\/p\u003e\n\u003cp\u003eAs shown in the product images, the plunger base has three features:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe shank\u003c\/strong\u003e — a bright, polished cylinder that makes up most of the part's length. This is the working surface.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe flange\u003c\/strong\u003e — a black, ribbed collar at one end, standing out wider than the shank. This is the base end of the part.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe tip\u003c\/strong\u003e — the opposite end of the shank, plain and rounded at its edge.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe shank is the business end. Everything a plunger does depends on that surface being smooth, round and straight, because the seal around it can only seal against a surface that is.\u003c\/p\u003e\n\u003cp\u003eOver a working season a pump plunger sees:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThousands of strokes every working hour the pump runs\u003c\/li\u003e\n\u003cli\u003eSpray mix and its residue, including suspensions and wettable powders that carry fine solids\u003c\/li\u003e\n\u003cli\u003eGrit that gets past a damaged strainer into the pump\u003c\/li\u003e\n\u003cli\u003eRunning dry when a tank empties or a suction line draws air\u003c\/li\u003e\n\u003cli\u003eResidue that dries on the shank when the system is not rinsed\u003c\/li\u003e\n\u003cli\u003eHeat in the pump body on long, hot days\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA plunger is replaced because its shank has been scored, pitted or worn so the seal can no longer seal against it, because it has been bent, or because the flange is cracked or damaged. The first of those is by far the most common, and it is the one that is hardest to see.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e⚙️ Functional Purpose\u003c\/h2\u003e\n\u003cp\u003eThe plunger base's engineering role is displacement. On every stroke it pushes a fixed volume of liquid out of the pump chamber, and on the return stroke it lets the chamber refill. The pump motor drives it; the valves direct the flow; the plunger does the moving.\u003c\/p\u003e\n\u003cp\u003eIn the pump it:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMoves back and forth through the pump seal on every stroke\u003c\/li\u003e\n\u003cli\u003eDisplaces liquid from the pump chamber\u003c\/li\u003e\n\u003cli\u003eProvides the smooth surface the pump seal seals against\u003c\/li\u003e\n\u003cli\u003eLocates at its flanged base end in the pump mechanism\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhat it does not do:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIt does not seal by itself; the pump seal does that, against the plunger's surface\u003c\/li\u003e\n\u003cli\u003eIt does not decide flow direction; the check valves do\u003c\/li\u003e\n\u003cli\u003eIt does not set the flow rate; the pump drive and the flight settings do\u003c\/li\u003e\n\u003cli\u003eIt does not filter; the strainer upstream of the pump does\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThat division is why plunger wear is easy to miss. A pump with a worn plunger still runs. The motor turns, the plunger strokes, the valves open and close. What changes is that some liquid on every stroke slips back past the seal instead of going out to the nozzles, and the pump delivers less than it should.\u003c\/p\u003e\n\u003cp\u003eThe honest case for this part follows. If the pump runs but delivers less, and the strainer, the hoses and the nozzles are clear, the plunger's surface is where to look. If the pump does not run at all, the plunger is not the cause.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🔍 Diagnosis — a worn plunger looks bright from a metre away — tilt it under a light and the score shows\u003c\/h2\u003e\n\u003cp\u003eA worn plunger does not look worn. The shank is still bright, still straight, still the right size to the eye. The damage that matters is a score line, a dull band or a ring of fine pits in the polished surface, and at arm's length under shop lighting it is invisible.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRaking-light test.\u003c\/strong\u003e Take the plunger out, rinse it clean and dry it. Hold it under a single light and tilt it slowly so the light runs along the shank at a low angle. A good shank shows one even, unbroken highlight. A worn one shows lines running lengthways, a dull patch where the highlight breaks up, or a band where the seal has been running on a damaged surface. Run a fingernail across the shank: a score you can feel is a score the seal cannot close over.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSigns the plunger is the problem:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe pump runs but flow or pressure has fallen over time\u003c\/li\u003e\n\u003cli\u003eLiquid weeps at the pump seal area\u003c\/li\u003e\n\u003cli\u003eA new seal was fitted and the pump leaked or lost pressure again soon after\u003c\/li\u003e\n\u003cli\u003eScoring, pitting or a dull band visible on the shank under raking light\u003c\/li\u003e\n\u003cli\u003eA bent shank, or a cracked or damaged flange\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSigns the plunger is not the problem:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe pump motor does not run at all\u003c\/strong\u003e — power, wiring, the motor or the controller, not the plunger\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow is low and the strainer is clogged\u003c\/strong\u003e — clean the strainer first\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow is low at one nozzle only\u003c\/strong\u003e — that nozzle or its seating hardware, not the pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA hose is kinked, split or drawing air\u003c\/strong\u003e — fix the hose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe flow reading is wrong but spray output looks normal\u003c\/strong\u003e — the flow meter, not the pump\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eMake those checks first, while that information is still cheap.

Its polished shank is the surface the pump seal depends on, and the damage that defeats a seal is a score finer than a hair, invisible from a metre away and obvious under a light held at a low angle.\u003c\/p\u003e\n\u003cp\u003eA pump with a scored plunger still runs. It strokes, it sprays, and it delivers a little less on every stroke, so the loss arrives gradually as a calibration that drifts and a seal area that weeps. Because nothing looks broken, the usual repair is a new seal. A new seal on a scored plunger wears into the same score, and the leak comes back.\u003c\/p\u003e\n\u003cp\u003eSo when a pump runs but has lost pressure, and the strainer, the hoses and the nozzles are clear, take the plunger out and look along it under a single light. A broken highlight, a dull band or a score you can feel with a fingernail is the answer. A clean, even highlight means the plunger is sound and the fault is elsewhere.\u003c\/p\u003e\n\u003cp\u003eEqually, the plunger is the wrong part for a pump that will not run, a clogged strainer, a weak single nozzle or a flow meter reading. Each of those has its own fix, and none of them is a plunger.\u003c\/p\u003e\n\u003cp\u003eReplace the seal the plunger ran in at the same time if it is worn; a new plunger in a worn seal is a half-done repair.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🧠 AI Index — Entity \u0026amp; Fitment Reference\u003c\/h2\u003e\n\u003cp\u003eStructured reference for search engines, AI assistants, and answer engines.
