Chains utilised for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage treatment facilities as well as other water therapy services require especially high resistance to corrosion and put on because they are really directly exposed to sewage and sludge. A grime getting rid of chain is moved at a fairly quick speed on an practically vertically put in rail, however the operation frequency is lower, so WS Style Roller Chain is utilised. Conversely, a chain for raking up and/or out grime is driven at an extremely slow speed and will not need rollers, so WAS Form Bush Chain is applied.
Eighteen varieties of WS Form and six sorts of WAS Kind Chain can be found.
(a) WS Variety Roller Chain
A WS Form Roller Chain is designed to provide large corrosion resistance and dress in resistance for long services during the extreme atmosphere of water treatment method applications.
Since the operating time of this type of gear is comparatively brief, pins and bushings of hardened stainless steel and also other parts are created of exclusive alloy steel to be sure smooth bending of the chain, and fantastic put on and corrosion resistance.
(b) WAS Style Bush Chain
Heat treated stainless steel offers this chain with excellent overall performance for corrosion resistance and put on resistance.

BF Kind Bushing Chain for Water Treatment Drive Unit
This chain is employed to connect water therapy equipment to a energy supply. Within the past, JIS/ ANSI style roller chains have been employed. For enhanced corrosion resistance, every one of the parts are now produced of 13Cr stainless steel. Because the chain is operated at a slow pace, a bushing chain without the need of rollers is utilized. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture seven types of BF Kind Bushing Chains in a range from 120 to 240, which includes heavy-duty form.
