SGH Super-heavy-duty Gravel Pumps

Engineered to handle highly abrasive slurries with particles up to 203mm, the SHG series represents the pinnacle of third-generation hydraulic pump technology. Designed for severe-duty applications in dredging, mining, and industrial sectors, it delivers exceptional efficiency, durability, and operational flexibility.

Key Features of SGH Super-heavy-duty Gravel Pumps

Advanced Hydraulics: High flow rates (180–5800 m³/h) and heads (20–85 m) with maintained wear resistance.
Abrasion-Resistant Construction: Proprietary high-chrome alloys (A05, A61, A14) for extended service life in gravel, sand, and slag.
Unlined Heavy-Duty Design: Enables smooth passage of large solids, eliminating liners and reducing maintenance.
Flexible Configuration: Outlet adjustable in 45° increments; supports multiple drive options and shaft seals.
Efficient Bearing System: Grease-lubricated taper roller bearings eliminate oil recirculation, lowering operating costs.
