Three Common Sealing Methods For Slurry Pumps

Released on Dec. 18, 2018

1. The common sealing form of slurry pump is packing seal. The added filler is in full contact with the shaft. The conveying medium is prevented from passing through for sealing purposes. This kind of sealing form may cause corrosion to the packing when conveying the corrosive material of the slag slurry. Therefore, the sealing pump end of the sealing form cannot transport toxic and corrosive liquids.

2. Mechanical sealing machine

The mechanical seal is that the slurry pump moving ring and the static ring are closely contacted by the spring in the axial direction to achieve the sealing purpose. The mechanical seal is reliable and hardly causes the slurry pump to leak. However, care should be taken to protect the friction surface from wear during installation. The seal is mainly suitable for conveying flammable, explosive, high temperature and high pressure, strong corrosive liquid, and makes up for the shortage of slurry seal pump.

3. Pay impeller seal

The impeller seal prevents the liquid from leaking through the impeller force of the reverse centrifugal force. The impeller shaft seal does not need shaft seal water, and does not dilute the slurry. The seal can be prioritized under the premise that the slurry is not allowed.
