1/4" Plastic Pumps
1/4" Plastic Pumps are compact, corrosion-resistant pumping solutions designed for low-flow transfer, dosing, and circulation of aggressive or high-purity fluids. Characterized by their 1/4-inch inlet and outlet connections (typically NPT or barbed), these small-scale pumps are constructed from engineered plastics like polypropylene (PP), polyvinylidene fluoride (PVDF), or polytetrafluoroethylene (PTFE). This material selection provides excellent chemical resistance to a vast range of acids, bases, solvents, and ultrapure liquids, making them ideal for applications where metal pumps would corrode or contaminate the process stream. Common types include miniature centrifugal, diaphragm, or peristaltic pump heads often paired with fractional horsepower motors for precise control.
These pumps are essential in laboratory, analytical, medical, semiconductor, and small-scale chemical processing applications where precise metering, leak-free operation, and material compatibility are paramount. They are used for tasks such as chemical feed, coolant circulation, sample analysis, and reagent transfer in OEM equipment and benchtop systems. The combination of small size, broad chemical compatibility, and precise flow control makes 1/4" plastic pumps a critical component for reliable and safe fluid handling in sensitive and demanding micro-scale environments.
