Molten salt pump application in domestic already has a history of more than 20 or 30 years, mainly in the chemical industry. In the chemical industry, the domestic new technology and complete sets of equipment introduced from abroad, so foreign molten salt pump is introduced into China.

Before 2000, the domestic petrochemical plants, the import of molten salt pump have the upper hand, more than from the quantity and quality of domestic brands, because services cannot be imported brands of molten salt pump localization, bring inconvenience, such as parts supply cycle is long, it is not convenient to on-site technical communication, coupled with expensive imported brands of molten salt pump, then using molten salt pump companies start to look for local services. Probably began in 2005, domestic molten salt pump has been basically replace imported molten salt pump.

Since 2005, jinan Warwick pump industry co., LTD., in the production of fused salt pump number increase at an annual rate of 30%, probably by the end of 2015, Warwick pump industry has more than 1000 the number of users at home and abroad, the main customers for the domestic chemical enterprises, such as petrochina, sinopec chemical enterprises, foreign customers mainly some middle-south Asia countries such as India, Thailand.

Solar-thermal industry application of molten salt pump requires its submerged depth is long, generally for 8 to 12 meters. Because solar-thermal power projects in need of molten salt at around 10000 cubic (100 mw) project, the molten salt reservoir is large, its height decides the submerged depth of the molten salt pump. Chemical industry in the application of molten salt pump, submerged depth generally less than 3 m, based on this, the domestic molten salt pump manufacturers, no results in the projects of field, it is domestic hot project purchasing imported brand of the main causes of molten salt pump.

According to jinan Warwick pump industry knowledge, according to the domestic production of fused salt pump manufacturer has a good technical reserves, whether it be a molten salt pump structure design, the material selection and production of fused salt pump equipment has not much difficulty, can fully meet solar-thermal power generation industry produce of molten salt pump.

According to the current situation, because of foreign brands of molten salt pump has some successful application performance, on the solar-thermal industry are unfamiliar with molten salt pump, molten salt pump is preferred import very realistic, is the right thing to do. But with the development of light industry, domestic molten salt pump will gradually replace the imported brand, because domestic molten salt pump localization and price advantage, after all. Preliminary forecast in 2021, domestic molten salt pump advantages will be fully recognized by people, that is, in 2021, the Chinese will molten salt pump is widely used in light industry, almost completely replace the imported brand.
