1935	Established as Daito Kogyo Inoue Seisakujo. Manufactured gear pumps for machine tools, gear pumps for hydraulic pressure, and universal ball joints.
1944	Reorganized as Daito Kogyo Co., Ltd.
1947	Developed and manufactured high-pressure gear pump for hydraulic pressure.
1950	As the chemical industry developed, R&D and production of gear pumps having resistance to heat, resistance to acid/alkali, and for high-viscosity liquids started.
1952	A mechanical seal was used for the shaft seal of gear pumps to give vacuum resistance, enabling the suction of liquid from vacuum tanks, transportation, and other uses.
1953	Osaka Office opened.
1954	Factory 2 constructed.
1961	Omiya Factory constructed. Commercial production facilities of compact and standard gear pumps completed.
1963	Capital increased to 60 million yen.
1967	Gear pumps for high polymer chemistry spinning dope developed.
1969	Series of NS type sanitary pumps for high viscosity liquids developed.
1971	Factory 2 renovated, test facilities for gear pumps constructed.
1983	Compact, high-speed FR-type gear pump for diesel oil/kerosene developed.
1986	Assembly plant of Omiya Factory completed.
2003	Seal-less gear pump MC type developed.
2013	Our heat-resistant seal-less gear pump received the first prize of Arakawa-ku’s New Products and Technologies Award. The company received the first prize of Tokyo Management Innovation Plan.
2014	5-axes control vertical machining center, 3D coordinate measuring machine, gear measuring machine and surface roughness measuring machine introduced.
