Pump Testing & Performance Analysis

Verifying that an overhauled or newly procured industrial pump performs strictly to design specifications requires rigorous empirical testing under controlled hydraulic conditions. Teflow Pumps provides comprehensive pump performance testing, hydraulic efficiency mapping, dynamic vibration analysis, and hydrostatic pressure testing in our Ahmedabad engineering test-bay facility.

Our test-bay infrastructure features precision calibrated electromagnetic flowmeters, multi-point digital pressure transducers, high-accuracy power analyzers, and variable frequency drive (VFD) controls capable of testing industrial pumps up to 150 kW motor ratings. We evaluate full head-capacity (H-Q) curves across the complete operating spectrum from shutoff head to maximum flow.

Testing protocols strictly conform to ISO 9906 Grade 1 and Hydraulic Institute testing standards. Our engineers record flow rates, total dynamic head, Net Positive Suction Head required (NPSHr), motor electrical input power, and overall wire-to-water hydraulic efficiency, identifying internal hydraulic slippage, impeller trimming discrepancies, and recirculation losses.

Dynamic vibration profiling represents an essential component of our validation protocol. We utilize calibrated triaxial accelerometers to capture real-time FFT vibration spectrums across bearing housings under varying throttle loads, ensuring vibration levels comply strictly with ISO 10816 Class I, II, and III vibration severity limits before equipment release.

For chemical pumps handling hazardous or corrosive media, our test protocol includes high-voltage spark testing across fluoropolymer linings and hydrostatic shell pressure testing up to 25 bar. Every tested pump is supplied with a formal certified test report featuring verified performance curves, electrical power draw logs, and vibration spectrum plots.

Our closed-loop hydraulic test infrastructure incorporates multi-diameter electromagnetic flowmeters, differential pressure transmitters, automated throttling valves, and high-frequency power quality analyzers connected to a centralized digital supervisory data acquisition (SCADA) system. This advanced instrumentation captures continuous high-speed data logs of dynamic head, volumetric flow rate, power draw, and electrical power factor across the full range of pump operation.

NPSH testing is conducted in a dedicated vacuum-sealed test suppression tank. By gradually reducing suction pressure through controlled vacuum evacuation while maintaining constant flow rate, our engineers detect the precise point where cavitation bubbles form and total dynamic head drops by 3% (NPSH3%). This critical measurement verifies that the pump will operate without cavitation erosion in your plant's specific suction piping configuration.

Dynamic vibration profiling is conducted simultaneously during hydraulic performance testing. We place triaxial high-frequency accelerometers on the drive-end and non-drive-end bearing housings of both pump and motor, capturing real-time FFT spectrums across 1X, 2X, blade-pass, and high-frequency bearing defect ranges. This ensures the unit complies strictly with ISO 10816 Class II and III vibration velocity limits across all operating points.

Every tested pump is accompanied by an extensive, certified engineering test dossier. The report includes plotted head-capacity (H-Q) curves, power consumption curves, hydraulic efficiency curves, NPSHr profiles, multi-plane FFT vibration spectrum plots, and certified hydrostatic pressure test certificates signed by our senior quality assurance engineers.
