BF Type Bushing Chain for Water Treatment Drive Unit
This chain is made use of to connect water therapy gear to a electrical power source. While in the previous, JIS/ ANSI variety roller chains have been utilized. For enhanced corrosion resistance, all of the elements are now created of 13Cr stainless steel. Because the chain is operated at a slow speed, a bushing chain without the need of rollers is employed. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 sorts of BF Variety Bushing Chains in the range from 120 to 240, together with heavy-duty sort.

Chains employed for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage therapy services and other water treatment facilities demand particularly substantial resistance to corrosion and wear given that they may be straight exposed to sewage and sludge. A filth removing chain is moved at a rather rapidly pace on an nearly vertically put in rail, although the operation frequency is reduced, so WS Variety Roller Chain is applied. Conversely, a chain for raking up and/or out grime is driven at an extremely slow speed and won’t need rollers, so WAS Style Bush Chain is used.
Eighteen sorts of WS Type and six kinds of WAS Kind Chain can be found.
(a) WS Sort Roller Chain
A WS Sort Roller Chain is made to provide large corrosion resistance and wear resistance for lengthy support in the significant environment of water treatment applications.
Because the working time of this type of equipment is relatively short, pins and bushings of hardened stainless steel together with other parts are produced of distinctive alloy steel to make sure smooth bending of the chain, and fantastic put on and corrosion resistance.
(b) WAS Form Bush Chain
Heat taken care of stainless steel delivers this chain with great efficiency for corrosion resistance and put on resistance.
