CNSME PUMP's Slurry Pump Volute Liner

Today we will take a look at the froth pump will encounter what kind of problems, encounter these problems, we should do?

First of all, one of our common problems is that the shaft power of the froth pump is too large, which will cause friction in the foam pump, misalignment or imbalance between the motor shaft and the pump shaft, which will also lead to bearing damage, excessive flow of the froht pump, and too tight belt of the driving device.

At this time, the corresponding solution is to eliminate friction, adjust the motor shaft and pump shaft, replace the new bearing, adjust the running condition of the foam pump, adjust the belt, so that the above problems will be solved.

froth pump also often encounter the problem is that the bearing of the froht pump is overheating, the bearing is easy to damage, replace the new bearing, the bearing grease of the froth pump is too much or too little, add grease to be appropriate, there is debris in the grease, replace the new grease.

The bearing life of the froth pump is too short, the motor end and the pump shaft are not aligned or uneven phenomenon occurs, the motor shaft and the pump shaft can be adjusted, the shaft of the froth pump is bent, it is necessary to replace the new pump shaft, the friction in the froth pump or the impeller is out of balance, we need to eliminate the friction, and then replace the new impeller. When there are foreign bodies in the bearing of the froth pump or improper grease, we can clean the shaft.

The material selection of the impeller of the slurry pump should be determined according to the specific working conditions and the characteristics of the conveying medium. 

Slurry pump impellers are available in a variety of materials, including high chromium cast iron, rubber, polyurethane and Stainless Steel. Each material has its specific advantages and application scenarios:

1.High chromium alloy cast iron: has good wear resistance and corrosion resistance, high hardness, can effectively resist the wear of solid particles. Suitable for conveying high concentration and high hardness slurry.

2.Rubber: has good wear resistance and corrosion resistance, can effectively reduce the noise and vibration of the pump. Suitable for conveying slurry containing corrosive media, such as acid and alkali solution.

3.Polyurethane: has high wear resistance and corrosion resistance, suitable for conveying high concentration, high hardness slurry, with a long service life.

4.Stainless-Steel:

In addition, the material of the slurry pump impeller also includes Cr26 material (high chromium alloy material), which is usually used for desulfurization and other projects. Other metal materials such as A07, A49 and A05 also have their own characteristics, A07 material has a strong abrasion resistance, suitable for strong abrasive conditions; A49 material has high chromium alloy wear resistance and good corrosion resistance, especially suitable for a variety of working conditions such as metallurgy, power plants, coal mines, etc. A05 material price is more civilian, wear resistance is better, a wide range of applications. The corrosion resistance of rubber is better than that of metal flow parts, and it is suitable for particles containing solid particles in the slurry and smooth and without sharp corners.

In summary, the material selection of the impeller of the slurry pump should be determined according to the specific use environment and medium characteristics to ensure the performance and life of the pump.

CNSME Pump, a professional manufacturer and supplier of slurry pumps, is honored to announce our participation in the 2024 Chile Mining Exhibition (EXPONOR CHILE). Our booth is now fully set up, and we sincerely invite industry professionals to visit us.

The 2024 Chile Mining Exhibition will be held from June 3 to June 6 in Atacama Desert, Antofagasta, Chile. This exhibition is one of the most significant events in the global mining industry, bringing together mining companies, suppliers, and experts from around the world, providing a platform to showcase innovative technologies and products.

Our booth number is 221, located in the central area of the exhibition hall. Although the booth size this year limits our ability to fully display all our products, we have prepared detailed product brochures and arranged for professional staff to provide on-site explanations. Here, you will have the opportunity to:
