Your pump’s efficiency lives or dies by the impeller geometry. We machine every impeller directly from your 3D model or 2D drawing. No generic blanks, no re-engineered approximations. We verify critical dimensions on a CMM before the parts leave our floor.
At a glance: ±0.01 mm tolerance on machined features, 5-axis CNC capability, lead time from 7 working days, no MOQ.
±0.01 mm on bores and mating faces, ±0.05 mm on blade profiles
Surface finish
Ra 0.4 µm on seal surfaces, Ra 1.6 µm standard, as-machined or bead blasted
Balancing
Dynamic balancing up to G2.5 grade (ISO 1940-1)
Inspection
Full CMM report, surface roughness test, material certs
Batch size
1 piece to 10,000 pieces, no MOQ
Lead time
7–15 working days for prototypes, 15–25 days for production runs
Location
Dongguan, China (factory direct, made in China)
Three reasons buyers send us their drawings
1. Batch-traceable quality. Every impeller gets a unique serial number. We track material heat number, tool paths, machine operator, and inspection results for that serial number. If a field failure happens, we can trace it back to the exact batch and process parameters within hours. You get a full traceability document with every shipment.
2. Inspection report per batch. We don't just say "it's within tolerance." You receive a dimensional report with actual measured values, not pass/fail ticks. For critical features like the hub bore and blade tip radius, we include CMM point-cloud data. This saves your QC team hours of re-verification.
3. One factory for CNC + stamping + springs + heat sinks. Your pump assembly might need a stamped housing, a spring-loaded seal retainer, or a heat sink on the motor driver. We run all four production lines under one roof. You send us the full BOM, we coordinate the machining, stamping, spring coiling, and heat sink fabrication. One purchase order, one shipping date, one responsible party.
Where these parts are used
Our CNC machined pump impellers go into applications where off-the-shelf castings fail. Typical uses include:
Chemical transfer pumps handling corrosive media — we machine impellers from 316L or titanium when standard plastics degrade.
Hydronic heating circulators — closed impellers with tight clearances for quiet, efficient operation.
Marine bilge and engine cooling pumps — bronze impellers that survive saltwater exposure.
Medical device fluid handling — small PEEK impellers for dialysis and infusion pumps, where material purity and dimensional repeatability matter.
Fuel and oil pumps for automotive test stands — custom vane profiles machined to match your flow curve.
Aerospace fuel boost pumps — aluminum impellers with thin blades, machined from solid billet for strength.
If your application needs a non-standard blade count, a specific vane angle, or a hybrid material combination, that's exactly what we do best.
Q: What is your MOQ?
A: No MOQ. We machine one prototype for testing or a thousand pieces for production. The unit price drops with quantity, but we won't turn away a single-piece order.
Q: How do you guarantee tolerance and quality?
A: We hold ±0.01 mm on critical features. Every batch gets a CMM inspection report with actual values. We also provide material certificates and, on request, a full PPAP package for automotive or aerospace buyers.
Q: What is your standard lead time?
A: Prototype impellers ship in 7–10 working days after drawing approval. Production runs of 100+ pieces typically take 15–25 working days. We can expedite to 5 days for an emergency replacement.
Q: Can you provide material certificates?
A: Yes. We supply mill certificates for all metals and plastics, including heat treatment reports for aluminum and stainless steel. For aerospace or medical work, we can provide full traceability documentation.
