Since 2005, the spark of an industrial dream was lit in Tianjin under the name "Kairun." The dream was born with a simple yet powerful conviction: to build submersible axial flow pumps with the longest service life and lowest failure rates for our nation.

The journey, however, never paused. From submersible axial and mixed flow pumps to sewage and mining slurry pumps, from individual pump units to self-developed gates and complete system solutions—every stride has been driven by an unwavering commitment to "innovation, customer-first, and the pursuit of excellence."

Nearly two decades of navigating rapid currents have turned the initial spark into a flourishing presence. Today, Kairun operates from a modern production facility spanning 9,000+ square meters, powered by a dedicated team of 200+ professionals in production, R&D, sales, and service.

Kairun is more than a pump manufacturer—we are your intelligent partner in fluid solutions. Guided by integrity, expertise, quality, and service, we stand ready to join hands with you in writing a grander chapter for industrial progress, together.
