Centrifugal pumps, horizontal, multistage sectional type PE 180-140 with sequential arrangement of impellers, are designed for pumping feed water with temperature not more than 180 °C, density (at t=165 °C) 902,5 kg/m3, with hydrogen index from 7,0 to 8,5 pH, with maximum concentration of solid particles 0,1%, maximum size of solid particles 0,2 mm. Pressure at the pump inlet is not more than 0.98 MPa.
For technological needs of the customer it is possible to take water from the intermediate stage to the required parameters.
APPLICATION
- feed water supply to boilers of TPPs.
- other areas of industry with similar parameters of working fluid.
FEATURES/ADVANTAGES:
- the first stage can be designed with a pre-engaged screw, which reduces the required cavitation reserve;
- the optimal ratio of impeller blades to the guide channels reduces vibrations.
- new design of mounting feet simplifies assembly/disassembly; shortens repair times
