Plastic Magnetic Drive Pump

The all-plastic magnetic drive pump is molded entirely from corrosion-resistant engineering plastics — PP, PVC or PVDF — with no metal in the wetted path, making it the economical choice for light-duty transfer of dilute acids, alkalis and other aggressive but ambient-temperature chemicals. A permanent-magnet coupling drives the impeller, so dynamic shaft seals are replaced by a fully sealed static design that is leak-free and eliminates the running, leaking and dripping problems mechanical seals on other pumps cannot avoid. With every wetted part formed from plastics and ceramics, the pump resists a broad range of corrosive liquids while keeping the conveyed medium free of metal contamination.

Structural features:

• Fitted with a branded motor for high efficiency and low noise.
• 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, 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.
