Water Pump for A rental company in Europe
A rental company came to us with a water pump programme for Europe. The brief was ordinary and unforgiving at the same time: a fixed launch window, a landed cost that had to survive freight and duty, and a part that had to match an existing sample. This case records what was specified, what went wrong in sampling and how the bulk order landed.
The starting point
- A supplier who changed material without saying so
- Documentation that arrived after the container shipped
- A fitment that looked right on paper and failed on the bench

What was specified
| Part | Water Pump |
|---|---|
| Client | A rental company |
| Market | Europe |
| Volume | 2,000 pieces across 2 specifications |
| Base material | Ceramic Composite |
| Sampling rounds | 2 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | SAE J431 |
How it was resolved
- The specification was rebuilt around Ceramic Composite and the tolerance locked before bulk.
- A pre-production sample was approved and kept as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and ratio specification.
- Documentation shipped with the goods instead of after them.

Result
- 2,000 pieces delivered inside the 10-week window.
- Unit cost held within 1.5% of the original quotation.
- Inspection-related rejection stayed under 0.5%.
- The specification is on file, so reorders reproduce the approved sample.
What we would repeat
Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
