HK International supplied the underwater and inboard pumps for CRCC’s cutter dredger ‘Tia Jian Jiao’. The HK-HE-3LS-216-45-90 for underwater and the HK-HE-3MD-216-45-90 for inboard are high efficiency three-bladed impellers. The pumps were tested at the harbour of Guangzhou and proved to have an 84% efficiency. Currently the dredger is working on the shore of Zhuhai (China) to reclaim land.
