ITT Industrial Process (IP) is a dynamic business expanding on a global scale. Headquartered in Seneca Falls, New York, IP offers a portfolio of world-leading brands in industrial pumps, valves and monitoring and control equipment, offshore water treatment systems, and plant optimization and efficiency systems, as well as aftermarket services and parts.
ITT Bornemann from Obernkirchen, Germany, has a long history of success as shown in Bornemann's timeline. Since the company was founded in 1853, our goal has been to respond to markets with products and solutions that are technologically outstanding and cost-effective. From that point on, Bornemann has been setting the pace. In 1934, for example, it patented the Twin-Screw Pump with external bearings. In the 1960s, the development of the triple-screw pump and the Progressive Cavity Pump led to more innovative solutions, and in the 1980s, Bornemann's multiphase pumps created commercial opportunities that had been previously unthinkable. Our manufacturing focus nowadays focuses on the twin-screw pumps.
A superior command of technology in nearly all areas of application has made Bornemann a worldwide leader in its field. Sales offices and subsidiaries worldwide ensure that there is immediate and professional support throughout all phases of the production process ranging from detailed advice extending to tailor-made engineering and finally including reliable maintenance of the installed pumps and systems. Efficiency, reliability and a high level of availability are the most important features that distinguish Bornemann pumps and systems.
Bornemann Twin-Screw Pumps are self-priming, double ended positive displacement pumps with external timing gears and bearings. Manufactured in over 80 sizes, their design provides complete axial balancing of the rotating elements and eliminates all metal-to-metal contact within the pump. They can handle virtually any non-homogeneous fluid, regardless of viscosity, lubricity or abrasiveness e. g. seawater, bitumen, molasses, lime, acid, caustic solution or hydrocarbon.
Principle
While pumping there is no metal-to-metal contact within the pump housing. This allows good pumping performance even with non-lubricating and corrosive and contaminated fluids.
As the pump rotates, the intermeshing of the two screws along with the pump housing form chambers. These chambers fill with the pumped fluid and move it from the suction side of the pump to the higher pressure discharge side of the pump.
The pump is designed to allow for reverse flow by simply changing the shaft direction. The suction becomes the dis-charge and vice versa, all without any modifications to the pump.
