Chains applied for collecting accumulated sediment in setting basins and sedimentation basins or getting rid of the collected sediment in sewage treatment method facilities and also other water therapy amenities require specially substantial resistance to corrosion and wear because they are immediately exposed to sewage and sludge. A grime getting rid of chain is moved at a reasonably rapid pace on an practically vertically set up rail, however the operation frequency is minimal, so WS Sort Roller Chain is applied. Conversely, a chain for raking up and/or out grime is driven at an incredibly slow pace and won’t demand rollers, so WAS Type Bush Chain is used.
Eighteen forms of WS Variety and 6 forms of WAS Variety Chain can be found.
(a) WS Type Roller Chain
A WS Form Roller Chain is intended to provide higher corrosion resistance and dress in resistance for long services during the serious natural environment of water therapy applications.
Because the working time of this type of tools is comparatively quick, pins and bushings of hardened stainless steel together with other parts are manufactured of special alloy steel to make sure smooth bending from the chain, and outstanding dress in and corrosion resistance.
(b) WAS Form Bush Chain
Heat treated stainless steel offers this chain with outstanding effectiveness for corrosion resistance and put on resistance.

BF Variety Bushing Chain for Water Treatment Drive Unit
This chain is utilized to connect water treatment products to a power supply. From the past, JIS/ ANSI style roller chains were made use of. For enhanced corrosion resistance, all the elements are now made of 13Cr stainless steel. Since the chain is operated at a slow speed, a bushing chain with no rollers is employed. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 types of BF Form Bushing Chains within a vary from 120 to 240, which include heavy-duty type.
