Ebara produces high-efficiency and high-performance pumps that meet the required operating conditions by using optimization technology combining the computational analysis of water flow inside the pump, and the unique design methodology of the internal geometry of pumps through simulations under prescribed ideal flow conditions (3D inverse design method).
Ebara has developed compact pumps with high flow based on computational flow analysis and optimization, such as a pump with a flow capacity of 50 m3/s, in which a suction velocity is twice that of conventional pumps.
High-pressure pumps for RO desalination plants, power plants, etc., are operated for long periods of time and required to achieve high efficiency. Flow optimization is indispensable for the design of high-efficiency pumps; for instance, the 3D inverse design method is used to design the shape of an impeller that ensures water flow with minimum energy loss.
Cryogenic pumps are used as main equipment for LNG transfer. The high suction performance required for cryogenic pumps directly leads to the economical effciency of LNG transportation. Pump cavitation deteriorates the suction performance of pumps and causes unstable operation. Ebara designs reliable pumps with high suction performance by using cutting-edge cavitation CFD and optimization based on the 3D inverse design method.
