Mechanical Seals Replacement

Here is a description of the procedures for inspection and replacement of the mechanical seals. Every pump has two mechanical seals.

Look for defects on the sealing surfaces such as scratches or wear. If a replacement is necessary, it is recommended to change all components to ensure proper operation. If an O-rings is deformed or damaged it is recommended also to replace the entire set of O-rings.

Single mechanical seal kit: it contains components 12A to 12J.

Double mechanical seal kit: It contains all components of the single mechanical seal plus components 12K to 12T; in this case the stainless steel seal housing (12J) is replaced by the seal housing (12L) which is already included on the double mechanical seal kit.

The mechanical seal should be installed using your hands only. No special tools are required unless it is indicated. You may use a hook to take out the O-rings from their grooves. Be careful not to scratch the seal faces.
