CG/CGH heavy-duty gravel pumps are primarily used to transport mixed media containing sand, gravel, slurry, and other solid particles. Depending on the specific model, they can be applied in sand and gravel mining, river dredging, port dredging, mine tailings discharge, land reclamation projects, and industrial sediment transport.

Compared with standard clean water pumps, heavy-duty gravel pumps must handle issues such as particle impact, abrasion, concentration fluctuations, and pipeline sedimentation. Therefore, model selection cannot rely solely on the pump's discharge size, motor power, or nominal flow rate; the medium properties and the entire conveying system must also be verified.

Based on technical evaluations, CG/CGH heavy-duty gravel pumps can be used for: sand and gravel conveying; river, lake, and port dredging; waterway maintenance and underwater dredging; land reclamation and sea enclosure projects; mine and tailings slurry discharge; integration with dredgers and desilting equipment; cleaning of sedimentation basins and mortar pits; and the transport of industrial slurries containing large particles.

Particle sizes, particle shapes, and solid contents vary significantly across different projects. Even when all classified as "gravel media," fine sand, coarse sand, rounded gravel, and sharp crushed stone present distinct requirements for the pump.

When selecting a model, it is recommended to provide the flow rate, head, maximum particle size, particle shape, solid content, slurry density, conveying distance, pipe diameter, and daily operating hours. The final model and materials should be confirmed according to actual operating conditions.
