Quality Assurance
Every Pump Tested Before Dispatch
Meibao's in-house quality system covers the full production cycle — from raw material chemistry to 48-hour run testing — so you receive a pump that performs exactly as specified.
Flow Testing
Wet test bench verification of Q-H curve, flow stability, and efficiency at rated duty point
Head & NPSH
Measured head at multiple flow rates; NPSH req. verified at full operating range
Vibration & Noise
ISO 10816 / ISO 3744 compliant measurement; results reported per pump
Pressure Testing
1.5× rated pressure held for 30 minutes — zero leakage required
48-hr Run Test
Continuous dry-run and wet-run test before dispatch — bearing temp, noise logged
