Product Overview
CQF Fluoroplastic Magnetic Drive Chemical Pump is a horizontal sealless centrifugal pump with fluoroplastic wetted components and magnetic drive for corrosion-resistant chemical transfer.
It eliminates mechanical seal leakage and minimizes maintenance by replacing dynamic seals with magnetic torque transmission in aggressive chemical environments.
It is applied in chemical processing, acid/alkali transfer, and corrosion-prone fluid systems requiring sealed and leak-free operation.

How to Select a Pump Model
- Determine required flow and total head (including system losses).
- Verify fluoroplastic compatibility with chemical media and temperature.
- Confirm working pressure ≤ 1.6 MPa and rated temperature ≤ 130°C.
- Match pump curve with system head & NPSH requirements.
- Evaluate required magnetic torque for viscous or dense media.
Engineering Notes
• Magnetic drive pumps eliminate mechanical seal leakage but require clean or low-viscosity service to maintain bearing lubrication.
• Fluoroplastic materials must be checked for chemical compatibility and temperature tolerance.
• Vortex or radial impeller selection depends on required head and flow balance.
• Pump installation must ensure level alignment and proper suction conditions.
Compliance & Quality Assurance
• Factory hydraulic performance test with rated curves.
• Isolation sleeve pressure integrity testing.
• Magnetic coupling torque verification.
• Material traceability and certification for fluoroplastic components.
• Optional third-party inspection per project requirements.
Safety Notice
• Do not operate under dry-running condition.
• Ensure pump is fully primed and system is degassed before operation.
• Do not exceed rated temperature or pressure limits.
• Disconnect electrical power before maintenance.
