KSB at WTT Expo 2005
The main focus at the KSB stand is on the company's comprehensive array of pumps and valves for heat transfer applications. For decades now, KSB products have been serving reliably in diverse heating circuits at plants in the chemical, petrochemical, food, wood-processing, textile and paper industries.
Increasingly stringent requirements regarding service life, safety and environmental protection have had major impacts on the designs.
Pump type series like Etanorm SYA (Fig. 1) and HPK feature very high efficiencies. They are fitted with special mechanical seals that are separated from the hot pump space by cooling paths. That way, thermal oil can be pumped at temperatures up to 350°C without cooling and up to 400°C with cooling.
Mag-drive pumps like the Etamagno are designed to rule out per se any escape of fluid. Thanks to a heat barrier between the drive and the hydraulic system, these pumps require no cooling water. A cooling and lubricating circuit that is separate from the main flow protects the plain bearings and containment shell against abrasive wear due to ferromagnetic particles entrained in the fluid pumped.
The Secochem Ex K series is the answer to explosion protection requirements. These canned motor pumps can still be used when conventionally sealed pumps must be ruled out for not satisfying pertinent regulations. Thanks to their external cooler, they can handle thermal oil at temperatures up to 400°C.
KSB also makes and supplies bellows-type globe valves (Fig. 2), non-return valves and strainers made of cast steel, nodular cast iron or grey cast iron for use in heat transfer systems. The hydraulically optimized flow paths of NORI 40 series Y-pattern globe valves make for very low internal pressure losses. Heat transfer systems equipped with these valves save lots of energy. Strainers made of the same kind of bodies as the valves filter solid particles out of the medium, hence protecting high-quality components from damage.
KSB's proprietary "PumpExpert" diagnostic system is also on show in Karlsruhe. This system provides straightforward and precise information on the pump, system and process status and thus helps users prevent expensive downtime and consequential costs.
As a pioneer in the area of large, variable speed pump drives, KSB Frankenthal also present their latest generation of speed control systems for ratings ranging from 0.55 kW to 45 kW. The new "PumpDrive" (Fig. 3) mounts directly on a motor, wall or control cabinet and is available in assorted variants kitted out with optional functions.
