1. Overview

The QHB Series Submersible Recirculation Pump is developed from submersible agitator manufacturing technology. It serves as dedicated equipment for secondary mixed liquor recirculation, denitrification, and nitrogen removal in wastewater treatment plants, and is also applicable to ground drainage projects requiring low-head, high-flow solutions.

2.Application

●  Secondary mixed liquor recirculation

●  Denitrification & nitrogen removal processes

●  Ground Drainage Systems

3.Characteristics    

●  Specifically designed for low-head, high-flow operation.

●  Stamped-formed main unit with excellent hydraulic performance and high efficiency.

●  Integrated lifting design enabling rapid underwater installation.

●  Equipped with dual mechanical seals and multiple motor protection mechanisms to enhance operational reliability.

• 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.
