Plastic 1 1/2" Pumps
Plastic 1-1/2" Pumps are high-capacity, industrial-grade pumps engineered for the safe and reliable transfer of highly aggressive chemicals, corrosive waste streams, and abrasive slurries where metallic materials would rapidly fail. Characterized by 1-1/2-inch NPT or flanged connections, these pumps are constructed from premium engineered thermoplastics such as polypropylene (PP), PVDF (Kynar®), or ECTFE (Halar®), offering near-universal chemical resistance to strong acids, bases, solvents, and halogens. Common designs in this category include large sealless magnetic drive centrifugal pumps, heavy-duty air-operated double-diaphragm (AODD) pumps, and recessed impeller vortex pumps, all prioritizing absolute containment, leak-free operation, and resistance to corrosion and erosion in severe service environments.
These pumps are fundamental to demanding processes in chemical manufacturing, aggressive wastewater and scrubber systems, metal finishing, mining, and semiconductor wet bench applications. They are specified for critical high-flow tasks such as bulk acid transfer, chemical batching, abrasive slurry pumping, tank farm operations, and filtration loop recirculation. The 1-1/2" connection size provides substantial flow capacity for main chemical process or waste lines, while the all-plastic wetted construction ensures long service life, prevents metallic contamination, and eliminates galvanic corrosion, making these pumps a cornerstone for safe, efficient, and compliant operation in the most challenging industrial fluid handling systems.
