Plastic 1" Pumps
Plastic 1" Pumps are heavy-duty, corrosion-resistant pumps engineered for high-flow transfer and circulation of highly aggressive chemicals, abrasive slurries, and ultrapure process fluids. Characterized by 1-inch NPT or flanged connections, these pumps are constructed from industrial-grade thermoplastics like polypropylene (PP), PVDF (Kynar®), or PTFE-lined materials, offering near-universal chemical compatibility where metal alloys would rapidly corrode or fail. Common designs in this category include large-capacity sealless magnetic drive centrifugal pumps, heavy-duty air-operated double-diaphragm (AODD) pumps, and recessed impeller vortex pumps, all built for durability, safe containment, and low maintenance in severe service environments.
These pumps are fundamental to demanding industrial processes in chemical manufacturing, aggressive wastewater treatment, metal finishing, and pulp & paper production. They are specified for critical applications such as bulk acid and solvent transfer, chemical batching, abrasive slurry pumping, and filtration system recirculation. The 1" connection size provides significant flow capacity for main process lines, while the all-plastic wetted construction ensures long-term reliability, prevents product contamination, and eliminates galvanic corrosion, making these pumps a cornerstone for safe and efficient operation in the most challenging corrosive and abrasive applications.
