First Pump® SHG Super-Heavy-Duty Gravel and Dredge Pumps
Engineered for Extreme Abrasion and Large-Particle Slurries
The First Pump® SHG Super-Heavy-Duty Grave and Dredge Pump represents the pinnacle of third-generation hydraulic technology, designed to deliver unmatched performance in the most demanding dredging, mining, and industrial applications. Built to handle highly abrasive slurries with large particles up to 203mm in diameter, these pumps combine cutting-edge engineering with robust construction to maximize efficiency, durability, and operational flexibility.
Key Features & Innovations
Advanced Hydraulic Design: Optimized for high flow rates (180–5800 m³/h) and heads (20–85 m), ensuring superior performance without compromising wear resistance.
Most Wear Duty Construction: High-chrome A05, Super-chrome A61 and Ultra-chrome A14 Alloy proprietary abrasion-resistant material extends service life in extreme conditions, ideal for gravel, sand, and slag applications.
Unlined, Heavy-Duty Structure: Engineered to pass large solids effortlessly, eliminating the need for liners and reducing maintenance downtime.
Adjustable Outlet Direction: Rotatable in 45° increments (8 positions) for flexible installation.
Multiple Drive Options: Compatible with direct drive, V-belt, hydraulic coupling, or reducer systems for seamless integration into diverse setups.
Versatile Shaft Seals: Choose from packing, auxiliary impeller, or mechanical seals to suit operational demands.
Grease-Lubricated Taper Roller Bearings: Heavy-duty bearings with high service factors reduce ownership costs by eliminating oil recirculation systems.
Technical Specifications
Max Particle Size: 203mm
Working Pressure: Rated to 1150 kPa
Flow Capacity: 180–5800 m³/h
Head Range: 20–85 m
Sizes Available: 150–400mm inlet/outlet diameters
Why Choose the SHG Gravel Pump?
Low Total Cost of Ownership:
No oil recirculation pumps required.
Reduced gland water consumption via close-tolerance lantern restrictors.
Ease of Maintenance:
Removable shaft sleeve (hardened or ceramic-coated) and split release collar simplify component replacement.
Robust one-piece casting with quick-adjust impeller clearance minimizes downtime.
Extended Service Life:
Large casing volume lowers internal velocities, reducing wear.
Side sealing vanes prevent solids intrusion into gland areas.
Heavy-duty shaft and cartridge bearings ensure reliability under heavy loads.
Applications
Ideal for pumping abrasive, large-particle slurries across industries:
Mining & Aggregates: Iron ore, coal, copper, gold, gravel, and mineral sands.
Dredging: River sand extraction, inland dredging, and mining vessels.
Industrial Processing: Slag granulation, sugar beet handling, and food production.
Infrastructure: Slurry discharge in tunneling (e.g., shield engineering) and hydrotransport.
Engineered for Excellence
The SHG series of gravel and dredge pumps leverage over six decades of expertise in coarse-particle pumping, offering a proven solution for severe-duty environments. Optional Accumin automatic lubrication systems enhance reliability in deck-mounted dredging setups, delivering precise lubricant dosing to critical components.
First Pump® SHG Gravel and Dredge Pumps: Where innovation meets endurance. Trusted globally for dredging, mining, and industrial challenges, it’s the ultimate choice for operators prioritizing efficiency, durability, and low lifecycle costs.
Explore the full range to meet your gravel and sand pumping needs—any application, any challenge.
