Factory Acceptance Tests for a High-Speed Disperser: Defining Pass or Fail
A buyer's guide to setting practical pass or fail checks for a high-speed disperser FAT, using the stated motor power, batch capacity, and speed range as reference points for RFQ and acceptance discussions.
Before signing off a high-speed disperser, decide how you will judge a factory acceptance test: will pass or fail rest on fixed measurements taken at agreed points, or on the supplier demonstrating the machine across its stated range? For a 22 kW unit intended for liquids in 200–1,000 L batches at 0–1,440 rpm, ask the supplier to propose test conditions that match your own product and batch size rather than a generic run.
Useful checks to negotiate include: does the disperser reach and hold the agreed speeds under load, and how is speed verified? What batch volume will be used for the test, and does it sit within the 200–1,000 L reference range? How will mixing performance be judged—by visual observation, sampling, or another agreed method? Ask what instrumentation and records will be provided, and whether the test includes the impeller and controls you will actually receive.
Define acceptance criteria in advance, including tolerances and who signs off. If a check fails, agree the retest procedure and any corrective action before shipment.
Before requesting a quote, confirm with the supplier which tests they can perform, the batch size and product used, how speed and power are measured, what documentation is supplied, and how pass or fail is recorded.
