Your fluid transfer systems demand components that withstand constant pressure, chemical exposure, and mechanical stress. When plastic parts fail, pumps seize, systems leak, and operations shut down. Poor-quality components cost more than money—they risk safety, efficiency, and reputation.
Polymar-ASM specializes in high-performance thermoplastic components for fluid transfer applications across Lancaster County and nationwide. From pump bodies to filtration components, our precision injection molding delivers parts that meet the strictest industry standards. With over 40 years serving fluid management manufacturers, we understand what makes components succeed or fail.
Standard plastic parts cannot handle the demands of modern fluid transfer applications. Your systems operate under conditions that push materials to their limits—high pressures, aggressive chemicals, temperature extremes, and continuous operation.
