Pumps - Positive Displacement: Market Size & Forecast 2026

The global positive displacement pumps market sits at approximately USD 18 billion in 2025 (base year), growing at 5.5 percent CAGR through 2032 to reach roughly USD 26.3 billion. The category occupies a structurally tight position: stainless steel 316 feedstock accounts for the single largest variable cost in a mid-size industrial unit, the US tariff stack on China-origin pumps now combines Section 122 and Section 301 List 3 obligations for a combined ad valorem burden approaching 35 percent, and EU CBAM transitional reporting on embedded emissions in imported steel components has been live since October 2023. The boring real-world reason this market does not grow faster than 5.5 percent is that the installed parc is mature in North America and Europe, and replacement cycles in water, wastewater, and chemical processing run 7-12 years. > **Analyst Take.** The call is to lock SS316-index
