Chains employed for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage remedy services as well as other water treatment method services require especially higher resistance to corrosion and put on since they are right exposed to sewage and sludge. A filth removing chain is moved at a reasonably speedy pace on an just about vertically set up rail, however the operation frequency is low, so WS Sort Roller Chain is utilized. Conversely, a chain for raking up and/or out dirt is driven at a very slow pace and doesn’t demand rollers, so WAS Sort Bush Chain is utilised.
Eighteen forms of WS Form and 6 types of WAS Kind Chain can be found.
(a) WS Form Roller Chain
A WS Style Roller Chain is made to supply large corrosion resistance and dress in resistance for lengthy services during the severe natural environment of water remedy applications.
Since the operating time of this sort of gear is relatively short, pins and bushings of hardened stainless steel as well as other elements are produced of special alloy steel to make sure smooth bending in the chain, and outstanding wear and corrosion resistance.
(b) WAS Form Bush Chain
Heat treated stainless steel presents this chain with exceptional efficiency for corrosion resistance and wear resistance.

BF Type Bushing Chain for Water Treatment Drive Unit
This chain is applied to connect water remedy equipment to a power supply. Within the past, JIS/ ANSI sort roller chains were made use of. For enhanced corrosion resistance, all the components are now made of 13Cr stainless steel. Since the chain is operated at a slow pace, a bushing chain devoid of rollers is made use of. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture seven forms of BF Variety Bushing Chains in the range from 120 to 240, including heavy-duty style.
