KSB's Etanorm SYT pumps have been a mainstay of process industries that need to handle high-temperature water or thermal oil. Capable of dealing with fluid temperatures as high as 350°C, these rugged, reliable pumps are available with flow capacities of up to 1,800 m3/h and heads as high as 102 m.Over the past two years, KSB has introduced a number of upgrades designed to reduce maintenance requirements and extend the service life of these dependable workhorses. These include:
- New shaft seal rings that provide bearings with more protection from hot thermal fluids passing through the pump.
- New deep-groove bearings with extra axial clearance to reduce bearing temperature. Bearing grease has been upgraded for improved resistance to dilution from synthetic thermal oils
- Vibration-proof Nord-Lock washers for the impeller nut.
- New upgraded mechanical seals for improved reliability and easier installation.
- Built-in leak detection to provide early warning of incipient seal failure
