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.

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.
Our CNC machined pump impellers go into applications where off-the-shelf castings fail. Typical uses include:
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.
Stop guessing whether a casting will meet your flow curve. Send us your drawing or 3D model, and we'll machine an impeller that matches your design intent exactly.
