Having spent decades in the pump manufacturing industry, I’ve seen firsthand how critical it is to have fire protection systems that never falter when lives and property are on the line. That’s why Shanghai Crowns’ Split Case Fire Pumps are designed with one goal in mind: uncompromising performance when it matters most. These pumps are built around a robust split-case design specifically tailored for firefighting. For industrial complexes, commercial high-rises, and municipal fire departments, these pumps are the backbone of reliable fire suppression. In a recent skyscraper project, three parallel pumps achieved full pressure within 18 seconds during a certification test, meeting GB50974-2014 standards with ease. The combination of cast iron casing and stainless steel shafts means they’ll maintain 95% of their performance even after a decade in harsh coastal environments. At the end of the day, fire protection isn’t about specs on paper—it’s about trust. Our Split Case Fire Pumps earn that trust through decades of refining every detail, ensuring they’re ready to defend what matters most, when it matters most.
