Chains employed for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage treatment services and also other water remedy services require particularly higher resistance to corrosion and wear given that these are right exposed to sewage and sludge. A dirt getting rid of chain is moved at a rather speedy speed on an nearly vertically installed rail, though the operation frequency is lower, so WS Style Roller Chain is applied. Conversely, a chain for raking up and/or out grime is driven at a very slow speed and will not require rollers, so WAS Kind Bush Chain is employed.
Eighteen sorts of WS Type and six varieties of WAS Style Chain are available.
(a) WS Variety Roller Chain
A WS Form Roller Chain is made to supply higher corrosion resistance and dress in resistance for long services in the serious atmosphere of water remedy applications.
Since the working time of this sort of tools is comparatively brief, pins and bushings of hardened stainless steel together with other parts are produced of specific alloy steel to be sure smooth bending with the chain, and superb wear and corrosion resistance.
(b) WAS Form Bush Chain
Heat taken care of stainless steel gives this chain with outstanding effectiveness for corrosion resistance and wear resistance.

BF Type Bushing Chain for Water Therapy Drive Unit
This chain is applied to connect water therapy tools to a energy source. During the previous, JIS/ ANSI form roller chains had been made use of. For enhanced corrosion resistance, the many components are now created of 13Cr stainless steel. Since the chain is operated at a slow speed, a bushing chain with out rollers is employed. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 varieties of BF Kind Bushing Chains in a range from 120 to 240, like heavy-duty variety.
