CNNC Jiangsu Nuclear Power Corporation awarded the Phase 3 & 4 contract ( 2 x MW 1060) to Alstom Thermal Power Nuclear and Shaanxi Diesel Heavy Engine Industry Co - to supply emergency diesel generators (EDGs).


They in turn have awarded DESMI with a contract for 44 pumps for different applications at this plant: 28 sets of our ROTAN® Gear (model PD81 /PD41), positive displacement pumps are used to transfer the fuel oil and the lubrication oil to the diesel engine generator.


ROTAN® models CD41EFM are used as discharging sump pumps, PD41 as lube oil charging pumps & fuel oil booster pumpe & fuel oil transfer pump, PD81 as prelubrification oil pumps.


The 14 sets of centrifugal pumps (EHL40-180 / EHL25-180) are used for the high temperature water pre-heating and water treatment purpose as well as discharging sump pumps.
