From;    Author:Stand originally

Odd screw pump was 1932 invent by French engineer Moineau, make a product by company of German PCM pump. 3 screw pump was 1931 be invented by Swedish IMO company and make. Factory of pump of industry of city of our country Tianjin develops a success at the beginning of 60 time marine high-pressured little flow 3 screw pump, patulous for major of pump of odd, double, 3 screw factory. Factory of Shenyang water pump produces pump of double, 3 screw at development of 60 time metaphase, 70 time develop a success 5 screw pump. After the 2AC screw milling machine of the production technique that factory of Tianjin industry pump recommended German Allweiler company 1984 and British Holroyd company and equipment of form a complete set, our country just begins batch to produce screw pump. Lagged behind 20 years full than abroad.
