self-priming magnetic drive centrifugal pump with plastic

The self-priming magnetic drive centrifugal pump is designed according to ISO2858 standards, featuring a composite steel and plastic structure for all fluid-contact parts. It incorporates an intermediate coupling, allowing easy maintenance—simply remove the coupling for repairs without dismantling the pipeline or motor.

Performance

• Flow rate: 1.8 to 400 m³/h
• Head: 15 to 125 m
• Max operating temperature: 200°C (plastic magnetic pump)
• Withstanding pressure: 1.6 MPa

Applications

• Conveying strong corrosive chemical media
• Handling organic and inorganic mixed media
• Suitable for chemical, pharmaceutical, food & beverage, environmental protection, and water treatment industries

Key Features & Advantages

• Self-priming function: Automatically expels air and draws in liquid at startup, eliminating the need for external exhaust or pre-filling and simplifying installation and maintenance.
• Plastic material: Pump body made of corrosion-resistant plastics (PP, PVC, PTFE, etc.) suitable for acids, alkalis, salts, and solvents. Lighter and ideal for chemical media.
• Magnetic drive: Magnetic coupling transmits power without mechanical seals, eliminating leakage risks. Perfect for toxic, hazardous, or volatile liquids.
• Centrifugal working principle: Accelerates liquid via impeller rotation, generating centrifugal force to deliver fluid efficiently. Self-priming enables operation without liquid pre-charge.
• No leakage: Magnetic drive eliminates direct contact and sealing problems, making the pump ideal for strict safety or pollution-prevention environments.
• Strong corrosion resistance: Plastic construction withstands harsh chemical media, preventing rust and long-term damage.
• Low maintenance: Simple design and no complex seals make it easier to maintain and reduce routine maintenance needs; magnetic drive avoids seal wear.
• Energy saving & efficient: Efficient power transmission reduces energy loss and operating costs.
• Low noise: Magnetic drive operation ensures smooth, quiet performance.
• Hanging structure: No need for water cooling box when transferring high-temperature media.

Industry Use Cases

• Chemical industry: Transfer of strong acids, alkalis, solvents, and other corrosive chemicals.
• Pharmaceutical industry: Safe, leak-free transfer of solvents, raw materials, and pharmaceutical liquids.
• Food & beverage: Hygienic, leak-free transfer of additives, dairy, flavorings, and liquids requiring non-polluting handling.
• Environmental protection: Conveying corrosive media in sewage, waste liquid, and gas treatment.
• Water treatment: Ideal for locations with difficult suction conditions, such as pools or low liquid levels.
