Product Overview

The CQF fluoroplastic magnetic drive pump is a sealed centrifugal pump specifically designed for the safe transfer of corrosive media. All wetted parts are made of reinforced polypropylene (PP) injection-molded, significantly enhancing corrosion resistance and expanding its application range. This pump is resistant to most organic and inorganic acids, bases, and salts, suitable for outdoor atmospheric exposure, and offers excellent stress corrosion cracking resistance. It is an ideal choice for handling corrosive chemical liquids without leakage.

Model Designation

CQF Fluoroplastic Magnetic Pump type

Key Features

  • Magnetic Drive Design: Utilizes a fully static sealing system to ensure zero leakage operation.

  • Excellent Corrosion Resistance: Reinforced polypropylene components make it suitable for a variety of corrosive media.

  • Low Noise Operation: Compact design reduces operating noise.

  • Environmental Safety: Ideal for the transfer of flammable, toxic, and corrosive liquids.

Service Conditions

  • The pump is suitable for normal operating conditions, ensuring the proper flow and pressure output.

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

  • All fasteners must be securely tightened before use to ensure safety and stability.

Protection Features

  • Overload Protection: Prevents damage to the pump during overload operation.

  • Overheating Protection: Automatically stops the motor when the temperature exceeds preset limits to prevent overheating.

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

Selection Criteria

When selecting the CQF fluoroplastic magnetic drive pump, the following standards should be considered:

  • Medium Type: Select a pump suitable for the characteristics of the medium being transferred.

  • Operating Environment: Choose a model suitable for indoor or outdoor use, based on the installation environment.

  • Flow and Head Requirements: Choose the appropriate flow and head capacity according to the system requirements.
