Evolved into a valveless mechanism, achieving more precise and accurate injection with smaller quantities.
Since the launch of Japan's first domestic chemical transfer hand pump (for drums) 35 years ago, the Handy Pro Pump HP series boasts a cumulative record of 100,000 units sold and a reputation for reliability. Through continuous research and development, we are constantly expanding our lineup of shapes and materials to meet customer needs. It is ideal for transferring chemicals from containers such as drums, polycans, pails, one-gallon cans, and cubitainers.

Company information
Water... as it is expressed in the ten teachings, shows us an infinite range of functions. Our company has been deeply involved with water for 50 years. In 1945, at the end of the war, the water supply rate was less than 20%. However, after the war, public health was prioritized in administrative matters, and simple water supply and dedicated water facilities rapidly spread nationwide. As the importance of disinfection in drinking water and food-related equipment became recognized, we began the manufacturing and sales of sodium hypochlorite as a synthetic disinfectant under food additive standards in early 1953. Later, we also produced disinfectants and sterilizers under pharmaceutical standards. In 1958, at the request and guidance of the supervising authorities, we developed the Myojo-type automatic chlorine sterilizer. This marked the beginning of our dual business in machinery manufacturing and chemical production. With the acquisition of patents and an increase in sales volume, we reorganized into a corporation in 1963. The support we received from many people during this time is beyond words. As we celebrate our 50th anniversary, we remain committed to the spirit of service to society and will continue to provide products and services that delight our customers.
