Chains utilized for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage treatment method facilities and other water treatment method facilities need especially high resistance to corrosion and dress in 
considering that they are immediately exposed to sewage and sludge. A filth removing chain is moved at a somewhat fast velocity on an just about vertically installed rail, though the operation frequency is low, so WS Style Roller Chain is utilized. Conversely, a chain for raking up and/or out dirt is driven at an incredibly slow speed and will not demand rollers, so WAS Variety Bush Chain is applied.
Eighteen varieties of WS Type and 6 sorts of WAS Form Chain can be found.
(a) WS Style Roller Chain
A WS Sort Roller Chain is intended to deliver higher corrosion resistance and dress in resistance for extended services in the serious atmosphere of water therapy applications.
Since the operating time of this type of equipment is comparatively quick, pins and bushings of hardened stainless steel and various parts are produced of particular alloy steel to make sure smooth bending with the chain, and fantastic dress in and corrosion resistance.
(b) WAS Variety Bush Chain
Heat treated stainless steel offers this chain with exceptional performance for corrosion resistance and wear resistance.
BF Variety Bushing Chain for Water Treatment Drive Unit
This chain is used to connect water remedy products to a power source. Within the previous, JIS/ ANSI form roller chains have been applied. For enhanced corrosion resistance, every one of the elements are now created of 13Cr stainless steel. Because the chain is operated at a slow speed, a bushing chain with no rollers is utilised. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 forms of BF Form Bushing Chains within a range from 120 to 240, like heavy-duty kind.
