Chains applied for collecting accumulated sediment in setting basins and sedimentation basins or getting rid of the collected sediment in sewage treatment services and other water remedy facilities need primarily higher resistance to corrosion and put on considering that they are really immediately exposed to sewage and sludge. A dirt getting rid of chain is moved at a rather fast velocity on an almost vertically set up rail, however the operation frequency is very low, so WS Style Roller Chain is used. Conversely, a chain for raking up and/or out grime is driven at an extremely slow speed and does not demand rollers, so WAS Style Bush Chain is utilized.
Eighteen types of WS Type and 6 forms of WAS Form Chain can be found.
(a) WS Form Roller Chain
A WS Sort Roller Chain is created to supply high corrosion resistance and put on resistance for extended support while in the extreme surroundings of water treatment applications.
Because the operating time of this kind of products is comparatively quick, pins and bushings of hardened stainless steel together with other components are manufactured of special alloy steel to be sure smooth bending with the chain, and outstanding put on and corrosion resistance.
(b) WAS Type Bush Chain
Heat treated stainless steel gives this chain with fantastic overall performance for corrosion resistance and dress in resistance.
BF Sort Bushing Chain for Water Treatment Drive Unit
This chain is made use of to connect water treatment tools to a electrical power supply. Within the past, JIS/ ANSI sort roller chains were applied. For enhanced corrosion resistance, the many parts are now created of 13Cr stainless steel. Since the chain is operated at a slow speed, a bushing chain with no rollers is used. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture seven sorts of BF Form Bushing Chains in a range from 120 to 240, including heavy-duty style.
