The twin screw pumps are self-priming, dry-running and resistant positive displacement pumps made of stainless steel or cast steel. They are designed for pressure ranges up to 25 bar, but can also be used in pressure ranges up to 50 bar. The range could be devided to 5 different pump sizes to cover a wide range of applications. The pumps can pump both volatile liquids such as petrol (short-chain HCs) and viscous substances such as bitumen.

The single-flow technology is extremely eco- nomical and, depending on the version, can be easily integrated into the existing system technology. Thanks to the design, individual components such as seals are easy to replace in just a few simple steps, making the pumps particularly efficient.

Overview of features of single-flow twin screw pump technology:

• flying bearing
• wide speed range
• various screw pitches and profile shapes for all applications
• extremely good suction properties due to very low NPSHr
• low pulsation and low shear
• flexible: pumping from diesel to heavy oil
• large viscosity band
• easy to maintain due to easy access to conveying elements and mechanical seal
• various material versions
