Diagnosing pump test curves like the senior tester
Test-bench data goes straight to an agent that reads the curve, names the likely fault the way the senior tester would, and drafts the certificate.

- Agentic AIIndustrial IoT
- Edge gateway on the test bench; agent runs on-premise or cloud.
- Flow / pressure / power meters (Modbus), PDF certificates, Tally, WhatsApp
It lives in the head of the senior tester.
He looks at a head-flow curve and says 'impeller rubbing' or 'air leak on suction'. He has seen thousands. The juniors send him photos of the gauge.
- Bench instruments are mixed brands and ages.
- Certificates must follow the standard the customer asked for.
- Failures must be explained in words the fitter will act on.
- 01
Instrument the bench
Flow, head, power and speed are logged automatically per test point.
- 02
Plot against the rating
The curve is drawn against the model's rated duty point and tolerance band.
- 03
Diagnose like the tester
An agent compares the curve with past failures and the tester's notes, and proposes a cause.
- 04
Draft the paperwork
The agent writes the test certificate; the tester signs or corrects it.
- Certificates issued without retyping readings.
- Junior testers get a diagnosis with reasons, not a guess.
- Every failed pump has a recorded cause.
Every test curve paired with the tester's diagnosis and the fix that worked.
- D1Raw bench time series per test point
- D2Model, stage and impeller metadata
- D3The tester's diagnosis and his corrections to the agent
- D4Rework action and retest result
Recorded on site and owned by the plant. The system uses it to keep learning your floor.

Diagnoses match the senior tester.
PILOT MEASUREMENT REQUIRED: agreement rate on failed pumps over a month.
Certificates take less time.
PILOT MEASUREMENT REQUIRED: minutes from test end to issued certificate.
Rework is right first time more often.
PILOT MEASUREMENT REQUIRED: retest pass rate after rework.
