Factory Acceptance Checks for Horizontal End-Suction Pumps
Define pass or fail criteria for a horizontal end-suction centrifugal pump FAT using the brief's reference limits: 2,321 m³/h flow, 160 m head and 16 bar working pressure.
Before signing off a factory acceptance test for a horizontal end-suction centrifugal pump, decide how the pump will be judged at its rated point and at the edges of its duty. A practical approach is to fix the test fluid, the rated flow and head, and the acceptance tolerance in the purchase order, then require the supplier to state the test stand's capability against the brief's reference values of 2,321 m³/h maximum flow, 160 m maximum head and 16 bar maximum working pressure. Treat these as catalog reference values, not as guaranteed results for the supplied model.
Ask whether the test will use water, as the application states, and at what temperature and suction conditions. Request the head-flow curve, efficiency and power readings at rated point plus shut-off and run-out checks, and agree pass or fail bands in advance. For pressure integrity, confirm the hydrostatic test pressure and duration and how leakage is judged. Vibration, bearing temperature and seal leakage should each have a recorded limit rather than a visual impression.
Before requesting a quote, confirm with the supplier which tests are standard, which are optional, what instrumentation is calibrated, how results are documented, and who witnesses acceptance.
