Key points for selection and use of slurry pump packing

TIME : 2025-06-26

1、 Characteristics and Applications of Fillers

The slurry pump packing is mainly composed of particles and connecting agents, and has the following characteristics:

Rich material selection: including PTFE (polytetrafluoroethylene), metals, etc.

Easy to install: easy to maintain, easy to replace.

Fillers are widely used in the following scenarios:

Transporting pumps containing particles such as sand, gravel, and sewage;

Transport high concentration slurry pump;

Pumps for transporting high-temperature and high-pressure media;

A pump that transports flammable gases.

2、 Performance of fillers

The performance of slurry pump packing is reflected in the following aspects:

Good wear resistance: can effectively extend the service life of the pump.

Good corrosion resistance: adaptable to different media environments.

Good sealing performance: prevents leakage from occurring.

Easy to operate: low maintenance cost.

3、 Suggestions for selecting fillers

When selecting slurry pump packing, it is necessary to fully consider factors such as medium characteristics, operating conditions, material costs, etc., and weigh the sealing performance and wear resistance of the packing:

Select appropriate packing materials based on the type of pump;

Select the corresponding packing type based on the characteristics of the medium;

Regularly inspect and replace the packing in a timely manner;

Pay attention to the installation sequence and compaction degree of the filling material.

4、 Inspection and maintenance of fillers

For the inspection and maintenance of slurry pump packing, the following points should be noted:

Regularly check the wear of the packing material;

When replacing the packing, it is necessary to ensure the sealing of the packing section;

Pay attention to the compaction degree of the filling material to avoid loosening;

Check the leakage of the packing and adjust the packing status in a timely manner.

5、 Precautions

Different materials of slurry pump packing have different chemical resistance, corrosion resistance, and wear resistance. Therefore, when selecting packing materials, it is necessary to choose suitable packing materials based on the characteristics of the conveying medium and the working environment, while also evaluating the cost and maintenance cost of the packing.

In addition, for parts that are prone to wear, materials with stronger wear resistance can be selected; For areas that are not easily worn, the requirement for wear resistance can be appropriately reduced. While considering the shape of solid particles and the acidity and alkalinity of liquids, materials with high hardness and good wear resistance should also be selected, such as hard nickel, ceramic coatings, and high chromium cast iron materials.

From the above analysis, it can be seen that reasonable selection and use of slurry pump packing can not only improve the working efficiency of the pump, but also extend its service life and reduce maintenance costs.
