LANHAI Dredging Engineering is a company which develops and manufactures dredging pump, pump parts, cutter heads, drag heads and components for cutter suction dredgers and trailing suction hopper dredgers.

Reduce downtime and operational costs with proven high-performance wear parts, trusted by leading dredging companies, fast delivery, and competitive pricing.

R&D and Testing:

For full‑cycle product development, we deploy professional tools including CFD hydraulic design software, Computer‑Aided Manufacturing (CAM) systems, CAPP computer‑aided process planning software, simulation analysis platforms, finite‑element analysis software and 3D design software.

Our product development covers the complete workflow: hydraulic design, structural design, 3D computer modelling, 3D computational fluid simulation & calculation, and computer‑aided simulated operational testing.

Through continuous dedication and technical pursuit, our manufactured products are comparable to pump series from established international brands, ranking among the industry’s top performers.

Equipped with advanced digital testing platforms, experienced processing and inspection teams, our workshop houses high‑precision inspection gear: 3D scanners, handheld spectrometers and hardness testers.

We fully conform to GB/T19001‑2016 / ISO 9001:2015 quality system standards and rigorously follow our quality, environmental, occupational health & safety management manuals. This safeguards product quality and supports precise custom‑made solutions for customers.
