Central drive system strong against rain, snow, and freezing! No need for sewage and sludge removal, and it supports a variety of torque.
Our company manufactures driving devices (floating type) for sedimentation pond sludge scraping, used in water supply and drainage systems, thickening, and clarifier fire systems. We offer two types: the center post type "N・SD series" and the center shaft type "VWML series," both of which are centrally driven. Unlike peripheral drive systems, which are prone to slippage of the running wheels due to heavy rain, heavy snow, or freezing, our design ensures stable water quality as there is no mud lifting. 【Features (common to both products)】 ■ Eliminates the need for sewage and sludge removal work, reducing operational costs ■ Equipped with a manual rotation device for easy adjustment, suitable for testing in locations without power ■ The torque meter is mechanical, using a worm gear, providing more stability than electric types ■ Standard equipped with a drive device protection mechanism for safe operation *For more details, please refer to the catalog.

Company information
Established in November 1950, we inherited the business of the former Special Gear Manufacturing Co., which had been active in the industry as a reducer manufacturer since the early Showa period, to manufacture various types of reducers and paddle wheel ash removal devices. Since our establishment, thanks to the support of our customers, our business has steadily developed, completing several capital increases. In May 1973, we built a new factory in Shin-go, Hyogo Prefecture (now Tanba City), enhancing our production system in the reducer division while also developing unique new products in the labor-saving machinery division. In recent years, we have been manufacturing various drive devices for water treatment, aqua aerators, as well as various reducers and small opening and closing devices for gates in rivers and dams, continuing to this day.
