First Pump® G/GH Heavy-Duty Gravel & Dredge Pumps
Engineered for Extreme Abrasion and Coarse-particles
First Pump® G/GH range of coarse-particle pumps delivers unmatched performance in handling highly abrasive slurries with large particles. Designed for demanding industries like dredging and gravel, these pumps combine high efficiency, low maintenance, and reduced ownership costs to provide reliable, long-term solutions for the most challenging applications.
First Pump® G/GH gravel & Dredge pumps are crafted using a variety of our proprietary advanced metals, including the remarkable Super-chrome A61 alloy. This selection of materials significantly enhances the pumps' abrasion resistance, enabling them to perform optimally in the most arduous applications, particularly in dredging and gravel - related operations.
Tailored Solutions for Diverse Challenges
G Series Gravel Pump
• Legacy of Excellence: For over 40 years, the G pump has set the standard for inland dredging and short-distance tunneling.
• Key Strengths:
• Ideal for moderate-head applications (10–60m) and shorter-distance slurry transport. • Optimized for inland subsoil dredging (rivers, lakes) and slag granulation plants. • High-efficiency handling of coarse particles like gravel, sand, and industrial slag. |
GH Series High-head Gravel Pump
• Next-Generation Power: Engineered for extreme workloads and extended operational ranges.
• Key Strengths:
• Built for high-head dredging and long-distance tunneling pipelines (e.g., marine environments, mining operations). • Reinforced components to withstand sustained high-pressure pumping. • Superior performance in precious metal processing (gold, platinum) and heavy industrial slag handling. |
Shared Innovations & Advantages
Advanced Abrasion Resistance
High-chrome Alloy Wear Parts: High-chrome Alloy A05, Super-chrome Alloy A61, Proprietary materials provide unmatched wear resistance, even in slurry environments with large, sharp-edged particles.
Unlined Construction: Eliminates liners, enabling direct handling of coarse solids without clogging or performance loss.
Cost-Saving Design
• Eliminates Oil Recirculation Pumps: Heavy-duty grease-lubricated bearings reduce energy costs and maintenance complexity.
• Reduced Gland Water Consumption: Close-tolerance lantern restrictor minimizes water usage, lowering operational expenses.
Effortless Maintenance
• Quick-Change Shaft Sleeve: Removable hardened steel or ceramic-coated sleeve protects the shaft and simplifies replacements.
• Split Release Collar: Streamlines impeller removal in larger pumps for faster servicing.
• One-Piece Casting: Robust design reduces through-bolt usage and simplifies impeller adjustments.
Extended Service Life
• Low-Velocity, Large-Volume Casing: Minimizes internal wear from abrasive particles.
• Side Sealing Vanes: Prevent solids intrusion into gland areas, reducing pressure and component degradation.
• Heavy-Duty Bearing Cartridge: Removable cartridge with large-diameter shaft maximizes bearing longevity.

Applications
First Pump® G/GH range of gravel and dredge pumps delivers industry-leading durability and efficiency in transporting highly abrasive slurries with large particles.
Engineered with durable all-metal, unlined construction, these pumps are designed to manage abrasive materials such as sand, along with large solids like rocks and shells. Their robust design makes them ideal for applications requiring the movement of coarse solids, including gravel handling, food processing (e.g., sugar beet operations), and industrial settings such as slag granulation facilities.
Ideal Applications
• Dredging: River, marine, and environmental sediment removal.
• Tunneling: Slurry transport in short- (G) or long-distance (GH) pipelines.
• Mining & Minerals: Coal, iron ore, bauxite, diamonds, and precious metals.
• Industrial: Slag granulation, aggregate processing, and even food-grade applications (e.g., sugar beet transport).
Enhanced Reliability with Accumin Systems
For deck-mounted installations, integrate the Accumin® automatic lubrication system to ensure consistent, precise lubrication of critical components, further boosting pump uptime and reliability.
Why Choose First Pump® G/GH?
• Proven Durability: Decades of field-tested performance in extreme conditions.
• Customizable Solutions: Tailored configurations for particle size, head, and distance requirements.
• Global Support: Expert technical guidance and rapid service from our engineering team.
