The recommended replacement period is 20 to 30 years. Is there any corrosion or unusual noise in the driving device for the sedimentation pond sludge scraper?
Our sludge scraper drive system is centrally driven, which prevents wheel slip due to bad weather. There is no pulsation in the sludge lifting, ensuring stable treated water quality. The center post type 'N-SD series' achieves compactness by incorporating a worm gear reducer. Changing the scraping speed can be completed simply by replacing the sprocket wheel. The center shaft type 'VWML series' is designed and manufactured for rake drive use. It is equipped with a lifting mechanism for the output shaft, allowing for easy torque adjustment. 【Features】 ■ Standard equipped with a drive protection mechanism ■ Manual rotation device for easy clearance adjustment and measurement ■ Issues can be resolved by raising or lowering the drive unit even if it stops due to over-torque ■ No need for removal work of wastewater and sludge *For more details, please download the PDF or feel free to contact us. ★ This catalog is a digest version; if you would like the full version, please feel free to contact us via the inquiry form.

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.
