Chains applied for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage treatment method services and various water treatment facilities call for specifically substantial resistance to corrosion and put on because they are right exposed to sewage and sludge. A grime removing chain is moved at a rather quick pace on an almost vertically installed rail, however the operation frequency is minimal, so WS Type Roller Chain is utilised. Conversely, a chain for raking up and/or out filth is driven at a very slow velocity and does not call for rollers, so WAS Style Bush Chain is employed.
Eighteen kinds of WS Type and 6 types of WAS Kind Chain can be found.
(a) WS Type Roller Chain
A WS Variety Roller Chain is intended to provide substantial corrosion resistance and dress in resistance for long services while in the significant environment of water treatment method applications.
Since the working time of this kind of tools is comparatively quick, pins and bushings of hardened stainless steel and also other parts are produced of particular alloy steel to make 
sure smooth bending in the chain, and excellent wear and corrosion resistance.
(b) WAS Type Bush Chain
Heat taken care of stainless steel presents this chain with fantastic overall performance for corrosion resistance and put on resistance.
BF Form Bushing Chain for Water Treatment method Drive Unit
This chain is used to connect water treatment method equipment to a energy supply. During the previous, JIS/ ANSI kind roller chains had been utilised. For enhanced corrosion resistance, all the components are now manufactured of 13Cr stainless steel. Because the chain is operated at a slow speed, a bushing chain without having rollers is utilized. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 forms of BF Form Bushing Chains within a vary from 120 to 240, like heavy-duty variety.
