Water pump VEY

solarstainless steelcirculation

The VEY and VNY are vertical mixed-flow molten salt pumps with high capacity and medium to high head. Its design includes hydraulics from proven ranges. These pumps have been engineered to balance high efficiency, low submergence, net positive suction head required (NPSHR) considerations, long lifetime and reliability as required for concentrated solar power. High efficiency Perfect pump configuration Low dead height of molten salt in the tank No external consumption Long lifetime and reliability Extensive references and wide experience The VEY and VNY molten salt pumps are used as: Cold and hot molten salt circulation pumps in parabolic trough concentrated solar power plants High-pressure cold molten salt feed pump in central tower concentrated solar power plants Hot molten salt circulation pump in central tower concentrated solar power plants Cold molten salt attemperation pump in central tower concentrated solar power plants Cold molten salt melting and drainage pumps in parabolic trough and central tower concentrated solar power plants Reduces temperature, protects and increases lifetime of the pump bearings Heat barrier between hot/cold sections Extended wear ring zone Clearances calculated considering all the relative expansions Bowl - HT carbon steel, chrome steel, HT stainless steel Impellers - HT carbon steel, chrome steel, HT stainless steel Shaft - HT chrome steel, HT stainless steel Column and discharge head - HT carbon steel, HT stainless steel Suction inducer for very low NPSHR All the impellers and bowls are provided with draining holes Efficient heat shield to limit the heat loss
