Pump Seal Installation Precautions
Jun 08, 2017



Water pump seal is one of the most effective ways to turn the mechanical body seal, and its processing accuracy is relatively high, especially the dynamic and static ring, if the disassembly method is not appropriate or improper use, the assembly of the pump seal not only failed to seal Purpose, Pump Seal and will damage the assembled sealing element.

When removing the pump seal, it is strictly forbidden to use the hand hammer and flat shovel to avoid damage to the sealing element.

If there is a pump seal at both ends of the pump, care must be taken during the disassembly to prevent this loss.

If the cover is loose, the sealing surface will be moved, and the static and dynamic ring parts should be replaced and should not be re-tightened. Because in the loose, Pump Seal the friction of the original operation of the trajectory will change, the contact surface of the seal is very easy to be destroyed.

If the sealing element is bound by dirt or agglomerates, Pump Seal remove the condensate and remove the pump seal.

Pump seal installation Note:

(1). Install the left part; mounted on the sealing plate

(2). Then install the right side of the dynamic ring, moving ring with the static ring sealing surface to be clean

(3). Re-install the key and the impeller. Good gasket and nut

Before installation, carefully check the assembly of the number of parts is sufficient, the components are damaged, especially the dynamic and static ring with or without bruises, cracks and deformation defects. Pump Seal If there is a problem, repair or replace the new spare parts.

Check that the chamfering of the sleeve or gland is appropriate and that it must be trimmed if it does not meet the requirements.

The pump seals the components and their associated assembly surfaces, which must be cleaned with acetone or anhydrous alcohol before installation. The installation process should be kept clean, especially moving, static ring and auxiliary sealing elements should be no impurities, dust. Moving, static ring surface coated with a layer of clean oil or turbine oil.

The upper cover should be carried out after the coupling is correct. Pump Seal Bolts should be tightened evenly to prevent the gland section skew, with a stopper or special tools to check the points, the error is not greater than 0.05 mm.
