Quality Control

 Test and inspection. 

 The test is divided into product performance inspection, factory inspection and other tests required. Each new product (including newly designed and newly modified products) must be fully tested for performance (including flow, lift, power, efficiency, cavitation performance, etc.), reliability test, and all tested and stabilized. . Factory inspections include water pressure detection, seal inspection, performance testing (flow, head, current) and user-required inspection items.
