Chains utilised for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage therapy amenities and various water remedy services require particularly high resistance to corrosion and wear since they are straight exposed to sewage and sludge. A grime removing chain is moved at a relatively quickly speed on an nearly vertically installed rail, even though the operation frequency is low, so WS Form Roller Chain is applied. Conversely, a chain for raking up and/or out grime is driven at a very slow pace and doesn’t require rollers, so WAS Sort Bush Chain is utilised.
Eighteen types of WS Kind and six kinds of WAS Variety Chain can be found.
(a) WS Style Roller Chain
A WS Variety Roller Chain is built to provide substantial corrosion resistance and wear resistance for extended service within the severe surroundings of water therapy applications.
Because the working time of this type of products is comparatively short, pins and bushings of hardened stainless steel along with other components are manufactured of exclusive alloy steel to ensure smooth bending in the chain, and excellent dress in and corrosion resistance.
(b) WAS Style Bush Chain
Heat handled stainless steel delivers this chain with excellent overall performance for corrosion resistance and wear resistance.
BF Sort Bushing Chain for Water Treatment method Drive Unit
This chain is utilised to connect water treatment method tools to a electrical power source. From the previous, JIS/ ANSI form roller chains were used. For enhanced corrosion resistance, each of the parts are now produced of 13Cr stainless steel. Since the chain is operated at a slow speed, a bushing chain without having rollers is applied. The sprockets are interchangeable with JIS/ ANSI 
roller chain sprockets.
We manufacture seven sorts of BF Kind Bushing Chains inside a vary from 120 to 240, which include heavy-duty kind.
