What is Daido Machinery Corporation

Founded in 1947, we are an independent pump manufacturer that celebrated our 70th anniversary in July 2017. As a “fluid specialist” and “pioneer of internal gear pumps”, we continue to offer “innovation” and “reliability” in various industrial sectors around the world.

Company Information

As one of the first companies to produce internal gear pumps in Japan, we have developed various improvements and new products over the years, and continued to challenge ourselves as “Daido Machinery Corporation” in sectors such as petrochemistry, pharmaceuticals, food products, and oil to accomplish countless achievements with high-temperature liquid feeding. In addition to the Daido internal gear pumps, we also manufacture and sell reciprocating vacuum pumps, vane pumps, and lobe pumps.
We offer the optimal pumps that match the needs of our customers upon request.

Our Products

Thanks to our advanced techniques and reliability, our products have been trusted by a majority of domestic listed chemical firms and have received high ratings from our users throughout the world. We have a wide range of achievements especially with high-viscosity and high-temperature liquid feeding.

Our internal gear pumps are known for being durable and easy to maintain. The general cost configuration of a rotating machine is said to consist of “15% initial costs, 85% maintenance”. By cutting down the amount of money required for maintenance due to the durability and user-friendliness of our products, we contribute to a total life cost reduction for our users.

We are also concentrating our efforts in expanding overseas. In 2006, we established Daido Hailong Pump(Shanghai) Co., Ltd as a 100% owned local subsidiary in Shanghai, China, and we also have multiple distributors in various countries throughout the world, including our representative office in Thailand. In addition to our affiliate companies, representative offices, and distributors, our business ranges widely throughout Europe (CE Marking), the Middle East, South America, Africa, and Russia.
