Standard Heavy Duty Gravel Pump XG(H)
Premium XG(H) gravel pumps serve as your ideal heavy-duty pumping equipment for gravel and coarse solids transport. As a professional Chinese manufacturer and supplier, we design this series as horizontal single-shell, single-stage, single-suction centrifugal pumps. All flow components are cast from high-chrome alloy, fitted with 3-blade closed impellers.
Thickened wear-resistant components and extra-wide internal flow channels endow the pumps with outstanding anti-clogging and anti-cavitation capacity, delivering steady operation under harsh heavy-duty working conditions. We supply these pumps at competitive factory bulk prices with fast delivery cycles.
Customers can select either electric motor or diesel engine power units, alongside flexible transmission solutions including direct coupling and belt drive setups. The pumps excel at conveying highly abrasive media mixed with big solid particles like sand and stone aggregates.
Common application scenarios include gravel dredging, sand extraction, tunnel construction, mine slurry transport, metallurgical slag handling, slag pelletization and alumina processing. All spare parts are fully interchangeable with Warman G series gravel pumps for easy replacement.

Features and Benefits
●Superior Anti-Clogging Performance
Adopting a single-casing structure paired with a three-blade closed impeller and large flow capacity design, the pump features ultra-wide internal flow channels. It allows smooth passage of large solid particles such as gravel and sand, effectively preventing blockage during heavy-duty conveying.
●Outstanding Anti-Cavitation Capacity
Designed with low NPSHr requirements, the pump adapts to low inlet pressure working conditions. It effectively avoids cavitation damage and maintains stable, continuous operation in complex on-site environments.
●Long-Lasting Wear and Corrosion Resistance
All wetted parts are fabricated from premium high-chrome alloy materials. The high-strength metal structure delivers excellent abrasion and corrosion resistance, greatly extending the service life of core pump components.
●High-Stability Shaft Design
The optimized large-diameter shaft with short overhang structure effectively reduces shaft deflection and operating vibration. This structural upgrade protects the bearing assembly and significantly prolongs its service life.
●Durable & Easy-Maintenance Bearing System
Equipped with heavy-duty grease-lubricated roller bearings and an integral removable cartridge bearing housing. It ensures reliable long-term operation and allows quick, precise adjustment of impeller clearance for easy daily maintenance.
●Versatile Sealing Solutions
Three mature sealing options are available to match diverse working conditions: packing gland seal, expeller centrifugal seal and mechanical seal, effectively preventing slurry leakage.
●Integrated Reinforced Frame
The rigid one-piece frame stably supports the entire bearing assembly. It adopts a precise positioning structure for convenient impeller adjustment, and uses minimal penetrating bolts to firmly fix the adapter plate, improving overall structural stability.
●360° Adjustable Discharge Direction
With a flexible clamp ring connection structure, the pump outlet can be freely rotated to any angle of 360 degrees, adapting to various pipeline layout requirements and improving installation flexibility.
●Flexible Transmission Modes
Multiple drive options are fully supported, including direct coupling transmission and various V-belt drive modes (top-mounted, side-mounted and reverse top-mounted), enabling flexible adjustment of pump operating parameters to meet different working demands.
