Stainless Steel 1 1/2" Pumps
Stainless Steel 1-1/2" Pumps are heavy-duty industrial pumps engineered for superior strength, corrosion resistance, and cleanability in demanding process and utility applications. Characterized by 1-1/2-inch NPT, flanged, or sanitary connections, these pumps are constructed from austenitic stainless steels—typically Type 304 or 316(L)—providing excellent resistance to oxidation, a wide range of chemicals, and high temperatures. Common configurations in this category include end-suction centrifugal, multi-stage high-pressure, and positive displacement rotary lobe or hygienic pumps, all built to deliver reliable, long-lasting performance in harsh, corrosive, or sanitary environments.
These pumps are the standard for critical applications in industries such as chemical processing, pharmaceutical and biotech (CIP/SIP systems), food and beverage production, marine, and power generation. They are used for high-flow duties like hot water or condensate circulation, aggressive chemical transfer, industrial washdown, and as main supply pumps in sanitary process lines. The 1-1/2" size offers substantial flow capacity for primary utility and process piping, while the stainless steel construction ensures durability, compliance with hygienic standards, and resistance to pitting and stress corrosion, making these pumps a fundamental asset for maintaining process integrity, safety, and operational uptime.
