In addition to the main impeller, adding a set of stirring impellers at the bottom can spray the deposited sludge into turbulence, enabling the water pump to achieve high concentration transportation without auxiliary devices. The unique sealing device can effectively balance the pressure inside and outside the oil chamber, maximizing the reliability of the mechanical seal. The motor adopts various protection measures such as overheating protection and water inlet detection protection, which can operate safely for a long time under harsh working conditions.
Used for extracting sand, silt, coal slurry, fly ash, sludge, tailings slurry, mineral sand, iron ore, rivers, lakes, reservoirs, ports and other sand and silt removal projects for construction purposes. It can also be used for sand removal in sedimentation tanks of industrial and mining enterprises such as steel plants, power plants, iron mines, oil fields, and for sediment removal in sewage treatment plants.

Structural characteristics

1. The whole machine is a dry bottom pump type, and the motor adopts an oil chamber sealing method with a mechanical seal inside, which can effectively prevent high-pressure water and impurities from entering the motor cavity.
In addition to the main impeller, there is also a stirring impeller that can stir the sediment settled at the bottom of the water into turbulence and extract it.
3. The impeller and stirring impeller and other overcurrent components are made of high hardness high chromium cast steel, which is wear-resistant, corrosion-resistant, and has strong drainage ability, and can pass through larger solid particles.
4. The motor is submerged underwater without being limited by suction, with a high slag absorption rate and more thorough dredging.
5. The overall equipment is simplified, no auxiliary mixing or spraying devices are allowed, the operation is simple, and the total investment of the unit is reduced.
6. The stirring impeller is directly close to the sedimentation surface and the concentration is controlled by diving depth. In cases where the medium ratio is high, auxiliary devices can be installed to increase the medium concentration

Conditions of Use

1. The power supply is a 50Hz/380V/660V three-phase AC power supply, and the capacity of the distribution transformer is 2-3 times the rated capacity of the motor.
2. The temperature of the medium shall not exceed 60 ℃ and shall not contain flammable or explosive gases.
3. The maximum weight concentration of solid particles in the medium is 45% for ash residue, 60% for slag residue, and within 40% for slurry concentration.
4. Diving depth of the unit: not more than 60 meters, the minimum diving depth is based on submerging the motor.
5. The working position of the unit in the medium is vertical, and the working state is continuous.

1. Bottom dredging of hydropower station dam
The bottom of the hydroelectric dam is equipped with a water tank, where the water inside the dam is collected and pumped out. The water tank is often filled with sediment, making it quite difficult to handle.
Directly place the submersible sand pump into the water tank for drainage, and at the same time, discharge the sediment together. The water tank will no longer be filled with sediment, and there is no need for manual sand cleaning.
2. Sedimentation cleaning plan for beneficiation plant
There are many sedimentation tanks, emergency discharge tanks, leakage and cleaning collection tanks in the beneficiation plant. The sedimentation of mud and sand in these places needs to be returned to the process or enter the tailings system. Due to the inconvenience of cleaning and transporting with large excavation equipment, manual cleaning is often used, which is labor-intensive and expensive.
The submersible sand pump can mix the sediment into a slurry through strong stirring with a mixing head and pump it at the same time. Provides a convenient method for cleaning sediment.

6. Sedimentation cleaning plan for underground water storage tank - solving the problem of mine mud discharge
Whether it is a metal mine or a coal mine, the underground main water tank needs to be cleaned of sediment before the rainy season arrives every year.
Usually, manual methods are used to clean sediment. The existing problems are high labor intensity, high labor cost, long cleaning cycle, and impact on production for manual cleaning. Use a submersible sand pump to clean sediment and pump mud, achieving mechanization of sediment cleaning.
7. Temporary cleaning of solid sediment in the oxidation ditch of the sewage treatment plant
8. Pumping of tailings from beneficiation tailings dam
According to the requirements of comprehensive utilization of mineral resources and environmental protection, as well as the potential economic value of tailings utilization due to technological advances, the recycling of valuable elements from old tailings and the use of tailings for underground filling are becoming increasingly popular. Using traditional excavator excavation, belt conveyor, and silo feeding methods not only requires high investment but also incurs high operating costs.
The sludge pump tailings recovery unit adopts the latest submersible mixing and mud pumping technology, which uses a powerful flying force mixer to mix the settled tailings particles into slurry, and then pumps it to the required place with a submersible sand pump.
General application
Extracting tailings from the tailings pond for reuse.
Cleaning and repairing of tailings pond.

14. Treatment of various sedimentation tank sludge
The sand pump has the characteristics of high efficiency, energy saving, wear resistance, corrosion resistance, reliable operation, high head, large flow rate (maximum mixed flow rate can reach 10-2000 cubic meters/hour), deep pumping depth (up to 60 meters deep), long conveying distance, and wide applicability. The solid-liquid mixture concentration during transportation can reach 60%. Can be equipped with an electric motor or a diesel generator. During the use of the sand pump, it is important to ensure that the concentration of the medium is not too high to prevent damage to the overcurrent components and affect the service life of the sand pump.
