Plastic-Lined Magnetic Drive Pump

The plastic-lined magnetic drive pump pairs a rugged metal casing with a PFA/ETFE fluoropolymer lining, so a single pump delivers the mechanical strength and pressure rating of a metal body together with the broad chemical resistance of a plastic pump. A permanent-magnet coupling drives the impeller, replacing dynamic shaft seals with a fully sealed static design that is leak-free and eliminates the running, leaking and dripping problems mechanical seals on other pumps cannot avoid. The fluoropolymer-lined wetted path keeps the conveyed medium isolated and uncontaminated, making the pump well suited to strongly corrosive and hazardous chemical media that would attack an unlined metal pump.

Structural features:

• A plastic-lined metal pump body provides both the high strength of a metal pump and the strong corrosion resistance of a plastic pump.
• The impeller and inner magnet are injection-molded as one piece for high strength; the rotating ring uses a high-performance plastic with good wear resistance that resists damage at high speed.
• The pump shaft is made of nano-grade ceramic and SSiC for strong corrosion resistance, suitable for conveying all kinds of chemical liquids.
• The outer magnet uses a high-performance permanent-magnet material with strong, durable performance and no demagnetization; dynamic-balance testing ensures high stability.
• Compact structure, attractive appearance, small footprint, low noise, reliable operation and easy maintenance.

Applications:

Widely used in the chemical, pharmaceutical, petroleum, electroplating, food, photo-processing, scientific research and defense industries for pumping acids, alkalis, oils, rare and valuable liquids, toxic liquids and volatile liquids, as well as for circulating-water equipment and filter presses. It is especially ideal for transferring hazardous liquids that are prone to leakage, flammable, explosive or toxic.
