Chains applied for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage remedy facilities and other water treatment facilities need specially high resistance to corrosion and wear because they may be straight exposed to sewage and sludge. A filth removing chain is moved at a reasonably speedy speed on an nearly vertically installed rail, even though the operation frequency is lower, so WS Form Roller Chain is applied. Conversely, a chain for raking up and/or out filth is driven at an extremely slow pace and will not require rollers, so WAS Sort Bush Chain is employed.
Eighteen forms of WS Form and 6 forms of WAS Type Chain are available.
(a) WS Kind Roller Chain
A WS Style Roller Chain is intended to supply high corrosion resistance and put on resistance for extended support within the extreme natural environment of water remedy applications.
Since the working time of this kind of gear is comparatively brief, pins and bushings of hardened stainless steel together with other components are created of special alloy steel to be sure smooth bending with the chain, and great wear and corrosion resistance.
(b) WAS Style Bush Chain
Heat handled stainless steel presents this chain with superb performance for corrosion resistance and wear resistance.
BF Variety Bushing Chain for Water Remedy Drive Unit
This chain is utilized to connect water treatment gear to a power source. Inside the previous, JIS/ ANSI kind roller chains were made 
use of. For enhanced corrosion resistance, the many elements are now created of 13Cr stainless steel. Because the chain is operated at a slow pace, a bushing chain devoid of rollers is employed. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 types of BF Sort Bushing Chains in a range from 120 to 240, including heavy-duty sort.
