The marine mud pumps used for large-scale dredging have good wear resistance, a wide variety of models, which is convenient for model selection, and can meet the environments with large flow rates and high heads. They are suitable for transporting sand and soil containing solid particles of various sizes, highly abrasive mortar, grout, tailings slurry, slag, etc. They are widely used in sand pumping in rivers, lakes and seas, sand and ore sand pumping in reservoirs, reclamation of land from the sea, sand filling for land reclamation, transportation of fly ash in power plants, transportation of tailings in the metallurgical industry, and in the hydraulic, power, mining and other industries.

Features of Marine Mud Pumps Used for Large-scale Dredging

1. They have the same high-efficiency performance as ordinary clean water pumps.

2. There are a series of various models (with a caliber of 50-300mm), which are suitable for various purposes.

3. The pump body, impeller, etc. are made of wear-resistant materials and can be used to transport media containing mill scale, sand, ore sand, etc.

4. Double-end face mechanical seals made of hard alloy materials and oil-lubricated are used to provide comprehensive and effective waterproofing.

5. A motor protector can be installed to prevent the motor from burning out due to overload, jamming, phase loss, water leakage, etc.

6. An automatic coupling device can be equipped, which is convenient for installation, hoisting, maintenance and repair operations.

7. An automatic control cabinet is equipped, and the pumps can operate alternately automatically.

8. The stirring submersible pump is equipped with a stirring device at the bottom of the pump. When the motor rotates, the stirring impeller impacts the surrounding media in a rotary manner, which can effectively stir up and discharge the surrounding sediments. The impact range is related to the size of the water pump.

Suitable Working Conditions:

1. Cleaning up the sediment in the coal settling pond of the power plant and discharging the coal slag, furnace slag or ash slag after coal combustion in the sedimentation tank.

2. Transporting the water slag of the blast furnace in the steel plant.

3. Cleaning up the precipitation of mill scale in the steel plant.

4. Sucking up fly ash and coal slime in various power plants.

5. Discharging and transporting the high-temperature smelting waste residue in the smelter.

6. Cleaning up the oxidized iron scale sediments in the turbid circulating water system and the swirl sedimentation tank of the steel hot rolling plant.

7. Cleaning up the high-temperature impurities in the sand settling tank of the heating company.

Operating Conditions of Marine Mud Pumps Used for Large-scale Dredging:

1. The normal power supply is a 50Hz/380V three-phase AC power supply. Special power supplies such as 60HZ/440V, 480V, 660V, and 1140V can be customized.

2. The medium temperature shall not be higher than 60°C. A high-temperature resistant motor shall be used if the temperature is higher than 60°C. The medium does not contain flammable and explosive substances.

3. The weight concentration of solid particles in the medium: 45% for ash slag and 60% for slag.

4. The submerging depth of the unit: Subject to submerging the motor, not more than 60 meters.

5. The working position of the unit in the medium is vertical, and the working state is continuous.
