Chains applied for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage remedy amenities together with other water treatment facilities demand primarily 
higher resistance to corrosion and wear because they may be right exposed to sewage and sludge. A dirt removing chain is moved at a fairly quickly velocity on an just about vertically installed rail, although the operation frequency is very low, so WS Sort Roller Chain is employed. Conversely, a chain for raking up and/or out grime is driven at an extremely slow speed and doesn’t require rollers, so WAS Kind Bush Chain is utilized.
Eighteen forms of WS Style and 6 sorts of WAS Form Chain can be found.
(a) WS Type Roller Chain
A WS Kind Roller Chain is made to deliver large corrosion resistance and dress in resistance for extended services in the severe surroundings of water treatment applications.
Since the operating time of this sort of equipment is relatively quick, pins and bushings of hardened stainless steel together with other parts are produced of exclusive alloy steel to make sure smooth bending on the chain, and superb dress in and corrosion resistance.
(b) WAS Type Bush Chain
Heat handled stainless steel provides this chain with superb performance for corrosion resistance and put on resistance.
BF Sort Bushing Chain for Water Remedy Drive Unit
This chain is utilised to connect water therapy products to a energy source. From the previous, JIS/ ANSI sort roller chains have been applied. For enhanced corrosion resistance, each of the parts are now manufactured of 13Cr stainless steel. Because the chain is operated at a slow pace, a bushing chain without having rollers is used. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 kinds of BF Kind Bushing Chains within a range from 120 to 240, like heavy-duty kind.
