CIRCOR is a leading global manufacturer of mission-critical flow control products and systems, specializing in pumps, valves, and related equipment for demanding industries such as Oil & Gas, Marine, Defense, Chemical & Petrochemical, and Power Generation.
The company operates under several well-known brands, including Allweiler, Houttuin, Imo, Warren, Zenith, and Tushaco, each recognized for reliability and engineering excellence.
Three-screw pumps are compact, high-power-density pumps designed for efficient and uniform fluid flow. Their three intermeshing screws ensure smooth, low-pulsation operation with high overall efficiency, and they handle a wide range of viscosities (0.3 to 100,000 cSt), gas contents and abrasive media. Flow rate is speed-dependent and independent of pressure, ensuring excellent controllability, while the self-priming design enables quiet operation even at pressures above 100 bar. Robust construction and wear-resistant spindles ensure long service life, and advanced materials make them suitable for lubricating oils, fuels and even corrosive or abrasive fluids.
Centrifugal pumps are hydrodynamic machines widely used to move liquids efficiently across many industries. They handle large flow volumes and a wide range of fluids, including corrosive, abrasive, hot, cold and contaminated liquids. Their simple, robust design ensures high reliability and long service life, and they are easy to maintain and repair, reducing downtime and operating costs. Highly efficient for water-like fluids across diverse operating conditions, the technology offers excellent versatility through material selection and customized designs — making it the most widely used pump technology worldwide.
