Chains employed for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage therapy facilities and also other water remedy amenities demand primarily higher resistance to corrosion and wear considering the fact that they may be immediately exposed to sewage and sludge. A filth removing chain is moved at a reasonably speedy velocity on an virtually vertically put in rail, though the operation frequency is low, so WS Form Roller Chain is made use of. Conversely, a chain for raking up and/or out 
dirt is driven at an incredibly slow speed and isn't going to require rollers, so WAS Sort Bush Chain is made use of.
Eighteen sorts of WS Variety and 6 varieties of WAS Variety Chain are available.
(a) WS Form Roller Chain
A WS Style Roller Chain is designed to supply high corrosion resistance and put on resistance for prolonged support during the severe surroundings of water therapy applications.
Since the operating time of this type of products is relatively brief, pins and bushings of hardened stainless steel and other elements are created of exclusive alloy steel to be sure smooth bending with the chain, and outstanding put on and corrosion resistance.
(b) WAS Form Bush Chain
Heat treated stainless steel supplies this chain with exceptional effectiveness for corrosion resistance and dress in resistance.
BF Type Bushing Chain for Water Remedy Drive Unit
This chain is utilised to connect water remedy products to a electrical power source. While in the previous, JIS/ ANSI form roller chains have been made use of. For enhanced corrosion resistance, each of the parts are now made of 13Cr stainless steel. Since the chain is operated at a slow velocity, a bushing chain devoid of rollers is utilised. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture seven types of BF Kind Bushing Chains inside a range from 120 to 240, including heavy-duty style.
