Feed water

The SYT range is designed for reliable operation with mineral and synthetic thermal oils, and hot water.

Electrical

• Variable speed operation / intelligent control by KSB frequency inverters.
• Wide range of KSB motors up to IE5.
• Optional automation with PumpDrive.

Mechanical / hydraulic

• Designed to deliver reliable operation with mineral and synthetic thermal oils up to 350 °C.
• Reliable venting during pump operation thanks to patented KSB VenJet® technology.
• KSB single mechanical seals and double mechanical seals in tandem arrangement with quench system deliver maximum operating reliability.
• Additional shaft seal ring.
• Special contour ensuring reliable removal of fluid leakage at the mechanical seal.
• Resistant bearings packed with special grease.
• Confined sealing elements and effective heat barrier.
• Impeller trimming as standard.
• High level of hydraulic efficiency verified experimentally and by CFD.
• "Cracked-joint" design of the coupling hubs enables straightforward assembly and dismantling.
• Double Cardan coupling provides even better compensation for shaft offset (optional).
• Fan impeller ensures efficient cooling (optional for Etanorm SYT).
• Wide range of applications possible: EN PN 16 & ASME.
• ATEX-compliant version available.
• Plain bearings available in carbon/SiC and SiC/SiC (for demanding fluids).
• Certified for marine applications to DNV GL.
• Service-friendly back pull-out design allows casing to remain in the system during maintenance.
• Casing wear rings and forcing screws for maintenance.
