• What technical advantages make the LM-QHB stand out?

  • Key features include a stamped-formed main unit for enhanced hydraulic efficiency, an integrated lifting design enabling rapid underwater installation, and dual mechanical seals along with multiple motor protections to ensure reliability in demanding environments.

• Does the installation of this equipment require pre-embedded parts?

  • No, only the wall-penetration pipe requires pre-embedding during the construction phase. Guide rods and lifting rods are secured using expansion bolts (ASTM A193 B7) and do not require additional pre-embedded components, simplifying the installation process and reducing construction complexity.
