KSB AG Vertical, Single- or Two-stage Spherical Casing Pump LUVA

Design Vertical, single- or two-stage spherical casing pump with single-entry radial impeller. Hermetically sealed, close-coupled pump without shaft seal. Suitable for maximum inlet pressures and temperatures. Integrated wet rotor motor to VDE / IEEE specifications. Air or heat barrier on option. Motor cooled by external heat exchanger via integratedrecirculat ion system. Product-lubricated bearings, no need forseparate oil supply systems. Designed to TRD (German Steam Boiler Code)standards. Applications In hot water recirculation in forced-circulation or once-through (forced-flow) boilers and combined maximum-pressure boilers. Waste heat recovery in the steel industry.
