7.5.3 Reassambling the motor section
NOTE
Before reassembling the motor section, check that all joints relevant to explosion
protection (flamepaths) are undamaged. Any components with damaged flamepaths
must be replaced. Only use original spare parts made by KSB for explosion-proof
pumps. Observe the flamepath positions specified in the Annex. Secure all screwed
connections closing off a flameproof enclosure with a thread-locking agent (Loctite type
243).
