Chains utilised for collecting accumulated sediment in setting basins and sedimentation basins or getting rid of the collected sediment in sewage therapy services and other water treatment services call for especially large resistance to corrosion and dress in considering that they are straight exposed to sewage and sludge. A grime removing chain is moved at a fairly quick pace on an practically vertically put in rail, even though the operation frequency is very low, so WS Style Roller Chain is made use of. Conversely, a chain for raking up and/or out dirt is driven at an extremely slow pace and won’t call for rollers, so WAS Type Bush Chain is utilised.
Eighteen kinds of WS Form and six forms of WAS Form Chain are available.
(a) WS Kind Roller Chain
A WS Type Roller Chain is intended to provide large corrosion resistance and put on resistance for extended services within the serious natural environment of water remedy applications.
Since the working time of this sort of tools is relatively quick, pins and bushings of hardened stainless steel and also other parts are manufactured of exclusive alloy steel to make certain smooth bending of your chain, and great put on and corrosion resistance.
(b) WAS Form Bush Chain
Heat treated stainless steel delivers this chain with great efficiency for corrosion resistance and wear resistance.
BF Form Bushing Chain for Water Therapy Drive Unit
This chain is used to connect water treatment gear to a power source. From the previous, JIS/ ANSI type roller chains had been made use of. For enhanced corrosion resistance, the many components are now made of 13Cr stainless steel. Since the chain is operated at a slow speed, 
a bushing chain with no rollers is made use of. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 sorts of BF Type Bushing Chains in a vary from 120 to 240, including heavy-duty kind.
