Chains employed for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage treatment facilities together with other water treatment facilities need specifically higher resistance to corrosion and wear due to the fact they are right exposed to sewage and sludge. A grime removing chain is moved at a fairly rapid speed on an nearly vertically set up rail, however the operation frequency is low, so WS Sort Roller Chain is utilized. Conversely, a chain for raking up and/or out filth is driven at an extremely slow velocity and won’t need rollers, so WAS Type Bush Chain is employed.
Eighteen kinds of WS Kind and 6 types of WAS Sort Chain are available.
(a) WS Variety Roller Chain
A WS Variety Roller Chain is designed to provide substantial corrosion resistance and dress in resistance for extended support within the extreme natural environment of water remedy applications.
Because the operating time of this kind of products is comparatively brief, pins and bushings of hardened stainless steel and various elements are made of distinctive alloy steel to make certain smooth bending with the chain, and great dress in and corrosion resistance.
(b) WAS Form Bush Chain
Heat treated stainless steel gives this chain with exceptional performance for corrosion resistance and put on resistance.

BF Type Bushing Chain for Water Treatment method Drive Unit
This chain is employed to connect water treatment gear to a energy source. While in the previous, JIS/ ANSI style roller chains were employed. For enhanced corrosion resistance, each of the parts are now created of 13Cr stainless steel. Since the chain is operated at a slow pace, a bushing chain without rollers is utilized. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 forms of BF Variety Bushing Chains in a range from 120 to 240, including heavy-duty type.
