What are the main features of sand suction pump

Sand suction pump is equipped with a set of stirring impeller at the bottom on the basis of the main impeller, which is capable of stirring the deposited sludge into a mixed liquid of water and solid particles, thus realizing high-concentration conveying without additional auxiliary equipment. Its unique sealing device effectively balances the pressure inside and outside the oil chamber, ensuring that the pressure at both ends of the mechanical seal remains balanced, maximizing the reliability of the mechanical seal and significantly extending its service life.


In addition, the motor can be added with various protection devices such as water inlet detection, overheating, etc. according to the user's needs, so that the sand suction pump can operate safely and stably even under the harsh working conditions.

The main features of sand suction pump include:
1. sand suction pump adopts dry motor under pump structure, the motor is equipped with mechanical seal, which effectively prevents high-pressure water and impurities from entering into the internal motor.
2. In addition to the main impeller, the sand suction pump is also equipped with a stirring impeller, which is capable of stirring the sludge deposited under water into turbulence for extraction.
3. The impeller, stirring impeller and other main overflow parts are made of high wear-resistant materials, which are wear-resistant, corrosion-resistant, non-clogging and have strong discharging ability, and can effectively pass through large solid particles.
4. sand suction pump is not limited by suction range, with efficient slag suction ability, more thorough dredging effect.
5. No need to equip auxiliary vacuum pump, reducing the investment cost.
6. no additional mixing or spraying device, easier to operate.
7. the motor is submerged in the water, no need to build complex ground protection and fixing device, more convenient management.
8. The stirring impeller directly contacts the sediment surface, and the concentration is controlled by the diving depth, realizing more flexible concentration adjustment.
9. The equipment works underwater, no noise and vibration during operation, and the site environment is more tidy.

10. From the driving end, the pump rotation direction is clockwise.
