In a hemodialysis system, a pump does far more than move fluid from one point to another. The dialysate delivery system must continuously circulate and control dialysate through the dialyzer, where water and solutes are exchanged across a semipermeable membrane. For this reason, stable flow, materia Read More

This guide explains how to evaluate pump material compatibility for safe and reliable chemical transfer. It compares metallic, plastic, and elastomer materials, including stainless steel, Hastelloy, titanium, PTFE, PVDF, polypropylene, FKM, EPDM, and Buna-N. The article shows how temperature, chemical concentration, pressure, abrasion, and dynamic mechanical stress affect pump casings, impellers, seals, diaphragms, and hoses. It also covers industry-specific chemical risks, compatibility testing, cleaning-cycle exposure, and multi-component evaluation, helping engineers prevent corrosion, swelling, embrittlement, leaks, contamination, downtime, and premature pump failure.
