Chains utilised for collecting accumulated sediment in setting basins and sedimentation basins or getting rid of the collected sediment in sewage treatment facilities along with other water remedy amenities require in particular higher resistance to corrosion and put on because they may be right exposed to sewage and sludge. A filth getting rid of chain is moved at a comparatively quick speed on an nearly vertically installed rail, though the operation frequency is very low, so WS Type Roller Chain is utilised. Conversely, a chain for raking up and/or out dirt is driven at an exceptionally slow speed and doesn’t need rollers, so WAS Type Bush Chain is utilised.
Eighteen kinds of WS Form and six types of WAS Type Chain can be found.
(a) WS Sort Roller Chain
A WS Kind Roller Chain is created to provide higher corrosion resistance and wear resistance for long support within the significant natural environment of water therapy applications.
Because the operating time of this type of equipment is comparatively short, pins and bushings of hardened stainless steel as well as other parts are created of particular alloy steel to guarantee smooth bending from the chain, and great dress in and corrosion resistance.
(b) WAS Form Bush Chain
Heat treated stainless steel provides this chain with outstanding effectiveness for corrosion resistance and dress in resistance.

BF Form Bushing Chain for Water Treatment method Drive Unit
This chain is used to connect water treatment tools to a electrical power source. Inside the previous, JIS/ ANSI type roller chains had been made use of. For enhanced corrosion resistance, all of the parts are now produced of 13Cr stainless steel. Because the chain is operated at a slow speed, a bushing chain devoid of rollers is made use of. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 kinds of BF Form Bushing Chains inside a vary from 120 to 240, including heavy-duty kind.
