Applications: Core flooding, emergency-cooling and residual-heat-removal systems, volume control systems, high-pressure charging, control-rod drive systems, high- and medium-pressure safety injection systems, auxiliary feed-water systems, start-up and shutdown feed-water systems.
RHM/RVM is a key Class II equipment for safety-related and auxiliary systems in nuclear power plants. SEC-KSB's technology is introduced from KSB, which has supplied more than 150 sets of similar products to NPPs around the world over past 4 decades.
SEC-KSB has provided Fuqing 5&6 - China's 1st HPR1000 reactors with RHMs, for which all the technical improvments and verification were done by itself.
Multistage centrifugal pump, double casing and radial split structure, forged casing, stable operation under extreme small flow rate;
Shaft surface strengthening technology, increases the fatigue characteristic and surface hardness;
Quick start without pre-lubrication;
Easy service due to pull-out design;
Patent design of casing wear ring and guide bearing reduces wear and increases operation stability.
