Plastic 1/2" Pumps
Plastic 1/2" Pumps are a specialized category of chemical-duty pumps engineered to safely handle aggressive, corrosive, or high-purity fluids where metal components would fail. Characterized by 1/2-inch NPT connections and construction from engineered thermoplastics like polypropylene (PP), polyvinylidene fluoride (PVDF), or chlorinated polyvinyl chloride (CPVC), these pumps offer exceptional resistance to a broad spectrum of acids, bases, solvents, and halogens. Common designs include magnetic drive (sealless) centrifugal pumps, diaphragm pumps, and air-operated double-diaphragm (AODD) pumps, which prioritize safety, leak-free operation, and contamination prevention in sensitive processes.
These pumps are essential in chemical processing, semiconductor manufacturing, water treatment, laboratory, and electroplating applications, where they are used for chemical transfer, filtration loops, chemical metering (dosing), waste stream handling, and recirculation duties. Their non-metallic wetted surfaces eliminate the risk of galvanic corrosion and metallic contamination, while their lightweight design simplifies installation and maintenance. The 1/2" size provides an optimal balance of flow capacity and precise control, making plastic pumps a critical, reliable component for maintaining process integrity and operator safety in challenging corrosive or ultrapure environments.
