Chains employed for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage treatment method facilities and other water treatment facilities demand in particular substantial resistance to corrosion and put on due to the fact these are right exposed to sewage and sludge. A dirt removing chain is moved at a rather quickly velocity on an practically vertically installed rail, however the operation frequency is very low, so WS Sort Roller Chain is made use of. Conversely, a chain for raking up and/or out filth is driven at a really slow speed and won’t require rollers, so WAS Variety Bush Chain is utilised.
Eighteen kinds of WS Kind and 6 kinds of WAS Sort Chain are available.
(a) WS Variety Roller Chain
A WS Style Roller Chain is made to supply high corrosion resistance and dress in resistance for lengthy service inside the severe atmosphere of water therapy applications.
Since the working time of this type of equipment is relatively brief, pins and bushings of hardened stainless steel and also other parts are manufactured of particular alloy steel to make certain smooth bending of the chain, and superb put on and corrosion resistance.
(b) WAS Form Bush Chain
Heat handled stainless steel offers this chain with excellent performance for corrosion resistance and wear resistance.

BF Type Bushing Chain for Water Treatment Drive Unit
This chain is applied to connect water remedy gear to a energy supply. While in the past, JIS/ ANSI sort roller chains have been used. For enhanced corrosion resistance, all the components are now produced of 13Cr stainless steel. Because the chain is operated at a slow velocity, a bushing chain without rollers is utilized. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture seven types of BF Style Bushing Chains in a vary from 120 to 240, together with heavy-duty kind.
