Chains applied for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage therapy facilities as well as other water therapy amenities need primarily higher resistance to corrosion and dress in considering the fact that these are immediately exposed to sewage and sludge. A grime getting rid of chain is moved at a rather quick speed on an nearly vertically installed rail, though the operation frequency is minimal, so WS Form Roller Chain is applied. Conversely, a chain for raking up and/or out dirt is driven at a really slow pace and won’t demand rollers, so WAS Type Bush Chain is employed.
Eighteen kinds of WS Type and 6 forms of WAS Sort Chain are available.
(a) WS Style Roller Chain
A WS Style Roller Chain is built to deliver substantial corrosion resistance and put on resistance for prolonged services during the extreme natural environment of water treatment method applications.
Since the working time of this sort of products is relatively short, pins and bushings of hardened stainless steel and other elements are produced of special alloy steel to guarantee smooth bending from the chain, and outstanding wear and corrosion resistance.
(b) WAS Type Bush Chain
Heat taken care of stainless steel supplies this chain with excellent efficiency for corrosion resistance and dress in resistance.
BF Variety 
Bushing Chain for Water Remedy Drive Unit
This chain is utilised to connect water remedy equipment to a power source. During the past, JIS/ ANSI kind roller chains had been utilised. For enhanced corrosion resistance, every one of the elements are now manufactured of 13Cr stainless steel. Since the chain is operated at a slow speed, a bushing chain devoid of rollers is employed. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 varieties of BF Sort Bushing Chains within a vary from 120 to 240, which include heavy-duty sort.
