Inside PEILI RO pump manufacturing
Pre-assembly Zone 2, 6S on the floor, servo lines, and 12 kg leak on every serial — what OEM buyers actually see in Jiangmen.
Field notes
What we tell OEMs before the sample ships.
Specification, noise, dual-source fit, and the leak benches behind a PEILI serial. Written for purchasing and engineering — not a catalog dump.

What a 12 kg leak test actually means
Sampling lotteries flood kitchens. Hydrostatic leak on every serial is how an OEM stays off review sites.
