Product Overview

The CQB-L Vertical Magnetic Drive Inline Pump is a newly developed, inline centrifugal pump based on years of experience in designing and manufacturing horizontal magnetic drive pumps. It combines the built-in installation concept of ISG centrifugal pumps with the leak-free advantage of magnetic chemical pumps. The installation dimensions are the same as the ISG inline centrifugal pump, and the CQB-L series represents the next generation of leak-free inline centrifugal pumps designed for chemical services.

Model Designation

CQB-L Vertical Magnetic Pipeline Pump for Chemical Transfer

Key Features

  • Magnetic Drive Design: Fully static sealing system ensures zero leakage operation.

  • Corrosion Resistance: Reinforced polypropylene (PP) materials enhance corrosion resistance.

  • Compact Design: Vertical inline structure saves installation space.

  • Low Vibration, Low Noise: Smooth operation with reduced noise.

  • Hydraulic Performance: Comparable to traditional CQB magnetic drive centrifugal pumps.

Engineering Overview

The CQB-L pump uses magnetic drive technology, with torque transmitted through a magnetic coupling, completely separating the drive motor from the pumped medium. This design ensures fully sealed liquid handling, eliminating the risks associated with shaft seals and ensuring safe, stable, and leak-free operation, while maintaining comparable hydraulic performance to the traditional CQB magnetic drive centrifugal pump.

Typical Applications

CQB-L Magnetic Inline Pumps are widely used in the following industries:

  • Chemical Processing

  • Maximum Working Pressure: ≤1.6 MPa

  • Maximum Suction Pressure: ≤0.2 MPa

  • Liquid Viscosity: ≤30 × 10⁻⁶ m²/s

  • Liquid Density: ≤1600 kg/m³

The pump is designed for continuous operation under stable hydraulic conditions.

Service Conditions

  • Regular checks on the sealing performance to ensure no leakage.

  • Ensure all fasteners are securely tightened before use to prevent vibration and loosening.

  • Avoid dry running to ensure proper lubrication and cooling functions.

Protection Features

  • Overload Protection: Prevents pump damage during overload operation.

  • Overheating Protection: Automatically stops the motor if the temperature exceeds preset limits.

  • Low Liquid Level Protection: Automatically detects liquid levels to avoid dry running.

Selection Criteria

When selecting the CQB-L magnetic drive inline pump, consider the following criteria:

  • Medium Type: Choose a pump suitable for the characteristics of the medium being conveyed.

  • Installation Environment: Select a pump system suitable for vertical inline installation.

  • Flow and Head Requirements: Choose the appropriate flow and head based on the system needs.
