BF Type Bushing Chain for Water Remedy Drive Unit
This chain is made use of to connect water remedy gear to a power source. While in the past, JIS/ ANSI type roller chains had been employed. For enhanced corrosion resistance, all the components are now manufactured of 13Cr stainless steel. Because the chain is operated at a slow speed, a bushing chain without having rollers is applied. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture seven forms of BF Kind Bushing Chains within a range from 120 to 240, like heavy-duty type.
Chains utilized for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage therapy facilities and also other water therapy services demand specially substantial resistance to corrosion 
and wear given that they can be immediately exposed to sewage and sludge. A filth removing chain is moved at a relatively rapidly velocity on an nearly vertically set up rail, however the operation frequency is very low, so WS Form Roller Chain is employed. Conversely, a chain for raking up and/or out dirt is driven at a really slow speed and doesn’t require rollers, so WAS Kind Bush Chain is utilized.
Eighteen forms of WS Type and six sorts of WAS Kind Chain are available.
(a) WS Type Roller Chain
A WS Variety Roller Chain is designed to supply large corrosion resistance and put on resistance for long services inside the severe surroundings of water remedy applications.
Since the operating time of this kind of equipment is comparatively quick, pins and bushings of hardened stainless steel and other components are manufactured of specific alloy steel to ensure smooth bending in the chain, and exceptional put on and corrosion resistance.
(b) WAS Kind Bush Chain
Heat treated stainless steel supplies this chain with outstanding effectiveness for corrosion resistance and put on resistance.
