CQB Fluoroplastic Magnetic Drive Pump for Leak-Free Chemical Transfer
The CQB fluoroplastic magnetic drive pump replaces a dynamic shaft seal with magnetic coupling and uses F46 or PFA wetted materials for leak-free transfer of hazardous corrosive liquids.
CQB Fluoroplastic Magnetic Drive Pump for Leak-Free Chemical Transfer
Static-seal chemical transfer for hazardous and highly corrosive liquids
The CQB fluoroplastic magnetic drive pump is engineered for services where leakage control and corrosion resistance are both critical. Magnetic coupling transfers motor torque through the containment structure, replacing the conventional dynamic shaft seal. This fully static sealing concept removes a common leakage path and is especially valuable when the liquid is corrosive, flammable, explosive, toxic or otherwise difficult to contain.

How The Magnetic Drive Works
The outer magnetic assembly is driven by the motor and transmits torque to the inner magnetic assembly without a direct shaft penetration through the pump casing. Because the CQB fluoroplastic magnetic drive pump does not depend on a rotating mechanical seal at the atmosphere boundary, the risk of seal-related dripping and vapor release is reduced. Correct operation is still essential: the pump must be filled, cooled and lubricated by a suitable process liquid and must never be allowed to run dry.
Corrosion-Resistant Wetted Materials
The liquid-contacting parts use F46 fluoroplastic lining for broad chemical resistance. PFA material can be selected for higher-temperature configurations. The CQB fluoroplastic magnetic drive pump can be considered for strong acids, alkalis, solvents and oxidizing media when all materials in contact with the liquid are compatible. The exact chemical name, concentration, temperature, density and solids content must be reviewed before selection.
Operating Range
The published family range covers flow rates from 1 to 1600 m³/h and heads from 5 to 125 m. Special PFA configurations can be selected for temperatures up to 160°C after the full duty has been evaluated. These values describe the series envelope; individual sizes operate within specific performance curves. A proper selection uses the normal and maximum duty points together with suction pressure, vapor pressure, system resistance and available NPSH.
Suitable Applications
The CQB fluoroplastic magnetic drive pump is used in chemical production, pharmaceutical processing, petrochemical facilities, chlor-alkali plants, fine chemicals, electroplating, metallurgy, new-energy manufacturing and industrial wastewater treatment. Typical duties include unloading corrosive liquids, feeding reactors, transferring acids between tanks, filter circulation and moving hazardous liquids through enclosed process systems.
Leakage Control Benefits
Eliminating the external rotating shaft seal can reduce routine seal replacement and the environmental concerns associated with visible leakage. The static containment design is useful when operators want a closed transfer path. However, a magnetic drive pump must be protected against dry running, blocked flow, excessive particles and overheating. System design should include appropriate level, flow or temperature protection according to process risk.
Selection Checklist
Please provide flow, total dynamic head, suction condition, operating temperature, liquid composition, concentration, density, viscosity and particle information. Also specify the motor power supply, frequency, installation environment and any hazardous-area requirement. The CQB fluoroplastic magnetic drive pump should not be selected solely by inlet and outlet size because hydraulic performance and internal heat generation depend on the actual duty point.
Installation And Start-Up
Keep the suction line short and airtight, support the pipework independently and remove welding slag or construction debris before commissioning. Confirm that the pump is completely filled and vented, verify motor rotation and open the required valves according to the operating procedure. Avoid dry running, closed-discharge operation for extended periods and sudden process changes. Monitor noise, vibration, outlet pressure and motor current during the first operation.
