Chains employed for collecting accumulated sediment in setting basins and sedimentation basins or getting rid of the collected sediment in sewage treatment method amenities along with other water therapy services require in particular high resistance to corrosion and put on because they’re immediately exposed to sewage and sludge. A filth getting rid of chain is moved at a fairly fast speed on an almost vertically installed rail, however the operation frequency is lower, so WS Style Roller Chain is utilised. Conversely, a chain for raking up and/or out dirt is driven at an incredibly slow speed and does not require rollers, so WAS Type Bush Chain is employed.
Eighteen kinds of WS Variety 
and six types of WAS Type Chain are available.
(a) WS Kind Roller Chain
A WS Type Roller Chain is made to provide high corrosion resistance and wear resistance for prolonged support within the extreme natural environment of water treatment applications.
Because the operating time of this type of products is relatively short, pins and bushings of hardened stainless steel and other parts are produced of particular alloy steel to be sure smooth bending from the chain, and great dress in and corrosion resistance.
(b) WAS Form Bush Chain
Heat taken care of stainless steel presents this chain with superb functionality for corrosion resistance and dress in resistance.
BF Variety Bushing Chain for Water Remedy Drive Unit
This chain is made use of to connect water treatment method tools to a electrical power source. Within the previous, JIS/ ANSI type roller chains were applied. For enhanced corrosion resistance, all the parts are now made of 13Cr stainless steel. Because the chain is operated at a slow speed, a bushing chain with no rollers is applied. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 kinds of BF Form Bushing Chains in a vary from 120 to 240, including heavy-duty type.
