Chains made use of for collecting accumulated sediment in setting basins and sedimentation basins or getting rid of the collected sediment in sewage therapy facilities along with other water treatment facilities call for particularly large resistance to corrosion and put on due to the fact these are directly exposed to sewage and sludge. A grime removing chain is moved at a rather rapid speed on an virtually vertically set up rail, though the operation frequency is lower, so WS Style Roller Chain is employed. Conversely, a chain for raking up and/or out grime is driven at an exceptionally slow velocity and will not call for rollers, so WAS Type Bush Chain is utilized.
Eighteen kinds of WS Variety and 6 varieties of WAS Form Chain can be found.
(a) WS Kind Roller Chain
A WS Sort Roller Chain is created to deliver higher corrosion resistance and put on resistance for extended support from the extreme environment of water therapy applications.
Since the working time of this sort of tools is relatively brief, pins and bushings of hardened stainless steel together with other elements are manufactured of specific alloy steel to guarantee smooth bending in the chain, and outstanding dress in and corrosion resistance.
(b) WAS Type Bush Chain
Heat treated stainless steel delivers this chain with superb functionality for corrosion resistance and wear resistance.

BF Style Bushing Chain for Water Treatment method Drive Unit
This chain is made use of to connect water remedy equipment to a electrical power source. In the past, JIS/ ANSI type roller chains had been used. For enhanced corrosion resistance, every one of the elements are now produced of 13Cr stainless steel. Since the chain is operated at a slow pace, a bushing chain with out rollers is used. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture seven sorts of BF Kind Bushing Chains in a vary from 120 to 240, which include heavy-duty kind.
