BF Style Bushing Chain for Water Treatment Drive Unit
This chain is utilised to connect water treatment method products to a electrical power source. While in the previous, JIS/ ANSI type roller chains were applied. For 
enhanced corrosion resistance, the many components are now produced of 13Cr stainless steel. Since the chain is operated at a slow velocity, a bushing chain devoid of rollers is applied. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 forms of BF Variety Bushing Chains within a vary from 120 to 240, including heavy-duty variety.
Chains utilised for collecting accumulated sediment in setting basins and sedimentation basins or getting rid of the collected sediment in sewage remedy amenities and also other water treatment services require particularly substantial resistance to corrosion and put on since these are immediately exposed to sewage and sludge. A filth removing chain is moved at a somewhat rapid pace on an practically vertically installed rail, though the operation frequency is minimal, so WS Type Roller Chain is employed. Conversely, a chain for raking up and/or out filth is driven at an extremely slow velocity and does not call for rollers, so WAS Form Bush Chain is utilised.
Eighteen varieties of WS Style and six kinds of WAS Kind Chain are available.
(a) WS Kind Roller Chain
A WS Variety Roller Chain is built to supply higher corrosion resistance and wear resistance for lengthy support while in the severe surroundings of water treatment applications.
Since the working time of this type of tools is relatively short, pins and bushings of hardened stainless steel and other parts are made of exclusive alloy steel to be sure smooth bending with the chain, and outstanding dress in and corrosion resistance.
(b) WAS Variety Bush Chain
Heat taken care of stainless steel provides this chain with excellent effectiveness for corrosion resistance and put on resistance.
