CQF Polypropylene plastic magnetic drive pump

A compact, magnetically‑driven centrifugal pump engineered for corrosive and volatile liquids. The pump body, cover and impeller are injection‑molded from reinforced FRPP (polypropylene) to provide broad chemical resistance to many acids, alkalis and salts and to resist outdoor atmospheric exposure and cracking. The magnetic drive eliminates a dynamic shaft seal, reducing leak risk and making the unit suitable for toxic, flammable or volatile fluids.

Key features

• Corrosion‑resistant construction: pump casing, cover and impeller in engineering FRPP (reinforced polypropylene) for chemical resistance and UV/outdoor durability.
• Sealless magnetic drive: containment by magnetic coupling removes the conventional shaft seal, lowering leak risk and maintenance for hazardous liquids.
• High‑durability wetted components: shaft and wear rings available in ceramic or silicon nitride; static/dynamic rings filled with PTFE to improve wear and chemical resistance.
• Flexible connections: inlet and outlet can be supplied with flanged or pipe (threaded) connections to match existing piping.
• Compact, low‑noise design: small footprint and quiet operation, suitable for installation in chemical processing, electroplating, pharmaceutical, food, petroleum, dyes, metallurgy, research labs and other industrial systems.
• Explosion‑proof option: can be coupled with an explosion‑proof motor for pumping flammable or explosive media.

Typical applications

• Transfer and circulation of acids, alkalis, solvents and salt solutions
• Handling toxic or volatile liquids where leak prevention is critical
• Support for filtration systems and closed circulation loops
• Electroplating baths, chemical processing, lab and pilot plants

Materials and wetted parts

• Pump body, cover, impeller: FRPP (reinforced polypropylene)
• Pump shaft: ceramic or silicon nitride
• Static/dynamic rings: ceramic or silicon nitride with PTFE fill

Benefits for procurement teams

This magnetic drive polypropylene pump offers a low‑maintenance, leak‑minimizing solution for corrosive and hazardous liquids. Its robust FRPP construction and ceramic/silicon‑nitride wear parts extend service life in aggressive chemistries while the sealless design reduces environmental and safety risk. Specify flange or pipe connections and an explosion‑proof motor option where required by site safety standards.
