Who we are
Factory & quality control
42,000 m² in Beilun, Ningbo: foundry, machining, assembly and test rigs in one plant.
Foundry
In-house casting for iron, ductile iron and high-chrome alloys. Every heat is spectrometer-checked before pouring, and traceability follows the casting to the finished pump.
CNC machining
12,000 m² of machining floor holds ISO 2768-m as the default tolerance class. Critical fits are checked on CMM with reports archived per serial number.
Assembly
One fitter owns each pump from bearing fit to final torque map. Torque values are logged against the serial number.
Test rigs
Performance rigs to 800 m³/h with calibrated instruments. Every pump is hydro-tested at 1.5× working pressure; witness tests are open in person or by video.
