NJP-7500C Automatic Capsule Filling Machine — 450,000 Capsules/Hour
The NJP-7500C fills 450,000 capsules an hour — the top of the NJP range. At this output the filler is one component of a line, not a standalone purchase.
1.Output: 450,000 capsules an hour
2.Indexing: 100DS cam indexing box
3.99.9% Success Rate: Advanced vacuum separation ensures flawless empty capsule loading.
4.Dual Patent Technology: Incorporates six major innovations, including two national utility model patents.
Is the NJP-7500C the right filler for you?
✓ This is a fit if…
- You need around 450,000 capsules an hour as a sustained rate
- You're running product development, stability batches or small commercial runs
- You're filling powder, granule or pellets
- You run 00# to 5# capsules
- Your room holds 21 °C ± 3 °C and 40–60% humidity
✕ Look elsewhere if…
- You need more than 450,000 an hour
- You're doing bench-scale R&D only → a semi-automatic filler costs a fraction of this
- Your powder is very fine and highly potent → an enclosed rotary machine with dust extraction is not the same as a contained or isolator system. Tell us your OEB band first
- You need under 330,000 an hour → the NJP-5500C costs less and does the same job at that rate
- This would be your first capsule line → at this output the filler is the easy part. Polishing, sorting, bottling and the upstream blend all have to keep up. Talk to us about the line
Output: 450,000 capsules an hour as a sustained rate, not a peak figure. We quote the speed you can hold through a shift.
Patented High-Precision Yield: Maintains a 99.9% separation rate and precise filling accuracy for consistent batch quality.
Zero-Waste Material ROI: Integrated recovery system ensures that stray material is captured in a clean loop.
Advanced Cleanroom Integrity: The oil-free dry vacuum pump meets international pharmaceutical standards with zero heat and no oil mist.

The D suffix is a configuration, not just a speed step. C-type machines use a water-ring vacuum pump and external-groove cam lubrication. The D adds a dry vacuum pump — no water to refill, no scale build-up — plus enclosed internal-groove cams with automatic timed oiling, and a nano anti-corrosion coating over the same pharmaceutical-grade stainless steel. If your formulation is corrosive or your maintenance team is thin, that’s what you’re paying for.
Butterfly valve hopper with forced vibration
Employs a vibration-assisted butterfly valve to force-feed powders with poor liquidity, solving traditional screw-feeding clogs.
100DS indexing box
Features an upgraded drive core with a 30mm diameter output shaft, providing superior stability than standard models.
Negative-pressure powder recovery
A negative pressure device at the filling station captures of powder from unseparated capsules for recycling.
Guideway-driven capsule seeder
An enclosed guideway transmission system ensures accurate capsule orientation and a significantly longer service life.
One-piece enclosed turntable
CNC-machined frame with dustproof skeleton seals prevents powder ingress, enabling 1 years of maintenance-free operation.
Keeping Powder Out of the Drive System
The enclosed turntable runs three years without internal maintenance or manual oiling with a dual-lip skeleton dust ring to prevent powder ingress.
How Much API Are You Losing per Batch?
A sophisticated negative-pressure system recycles stray powder, delivering cost savings for high-volume runs.
Running at 450,000/h Without Losing Fill Accuracy
Unlike smaller models, the NJP-7500C utilizes a 10-station workflow to ensure more precise capsule separation and locking at higher speeds.
Industrial Applications
Changeover: what you change and how long it takes
What you changed | What gets adjusted | Roughly how long |
Same capsule, different fill weight | Tamping pin depth on the dosing station | 15-30mins |
Fill weight beyond the adjustment range | Swap the dosing disc for a different thickness | 15-30mins |
Different capsule size | Full tooling set: upper and lower modules, tamping pins, capsule tubes, alignment combs, feeding combs, dosing disc, alignment bars | 15-30mins |
Dosing disc thickness is the second lever. When tamping depth reaches its mechanical limit and you still can’t hit your target fill weight, you change the disc rather than fighting the machine. It’s a physical volume change, not a calibration.
The gaps matter more than they sound. Dosing disc to copper ring: 0.08–0.12 mm. Isolation block to disc: 0.05–0.1 mm. Every disc change means resetting the second one. Too tight and the disc binds; too loose and powder leaks and your fill weight scatters.
Cleaning is the long part. Between products, the powder hopper, dosing ring, upper and lower modules, tamping pins and dosing disc all come out. Parts above the machine table are cleaned with alcohol on lint-free cloth — never gasoline, kerosene, hydrogen peroxide or acetone.
What to check before you order — from any supplier
Ask to see the machine running your powder, not a demo powder
Lactose and starch run beautifully on everything. Ask for a video of your own material, or send a 2 kg sample for a trial run. Any factory that won't do this is telling you something.
Ask what the sustained rate is, not the maximum rate
Catalogue output figures are peak numbers. Ask what the machine holds over an eight-hour shift with your fill weight and your capsule size, and what the reject rate looks like at that speed.
Ask for the operating manual before you pay
If the adjustment procedures aren't in it — tamping pin height, dosing disc clearances, vacuum settings — your operators will be calling the factory every time something drifts.
Ask which parts are wear parts and what they cost
On a capsule filler that means seals, tamping pins and the dosing disc. Get the list and the prices in writing with the quotation.
Ask what the electrical supply actually is
Most machines from Asia ship at 380V / 50Hz as standard. Confirm in writing that yours will arrive configured for your plant, and whether the output figure still holds after the change.
Ask who installs it and who trains your operators
"We provide installation support" can mean an engineer on your floor or a PDF. Ask which, ask for how many days, and ask what happens if commissioning takes longer.
Why Choose AIPAK
Why buy this machine from us
Accuracy you can check Fill weight accuracy is ±3% on pharmaceutical powder, ±4% on herbal powder. We run your material at factory acceptance testing and give you the actual figures for your formulation — not a number off a brochure.
The manual your operator can actually use An English operating and maintenance manual with the adjustment procedures in it — tamping pin height, dosing disc gaps, vacuum pressure. Ask to see it before you order.
Installation and training on site Our engineers install it, dial it in on your powder, and train your operators before they leave.
Factory-direct engineering You buy from the plant that builds the machine. Custom tooling, feeder configurations and change parts are a conversation with our engineers, not a request passed down a chain.
NJP-7500C Flagship Performance FAQ
No. By utilizing an Guideway-driven capsule seeder rack, we ensure that capsule orientation remains flawless despite the high velocity. Combined with our tamping pin technology, the machine maintains a consistent filling accuracy of ±3.0% for Western medicine.
Our integrated powder recovery device uses negative pressure to instantly inhale powder from any unseparated capsules directly into a collector. This uncontaminated powder can be recycled and reintroduced into the production cycle without disinfection, providing a massive ROI on expensive APIs.
The ten-station turntable is a one-piece forming structure with no splicing gaps, protected by dustproof lip skeleton seals. The enclosed turntable runs three years without internal maintenance or manual oiling, requiring no refueling or internal cleaning, which drastically lowers your long-term OPEX.
Unlike traditional pumps, our imported dry vacuum pump does not generate heat. It meets international (FTA) pharmaceutical gas standards and operates silently, ensuring that the temperature control of your GMP workshop remains undisturbed.
Batch records and parameter settings are held in the retentive memory of the Siemens PLC, so data written before the interruption is preserved and available when power is restored. The machine stops in a controlled state and requires operator acknowledgement before restarting, so an interrupted batch is never silently resumed. An uninterruptible power supply for the control cabinet is available as an option where site power is unstable.
For standard NJP-7500C models, our lead time is 4-6 weeks. Shipping to major U.S. ports (e.g., LA or New York) typically takes an additional 3-4 weeks.
