Chains applied for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage treatment method facilities and various water therapy facilities demand especially large resistance to corrosion and put on because they can be right exposed to sewage and sludge. A dirt getting rid of chain is moved at a fairly quickly velocity on an pretty much vertically set up rail, although the operation frequency is low, so WS Sort Roller Chain is utilised. Conversely, a chain for raking up and/or out filth is driven at an extremely slow speed and doesn’t need rollers, so WAS Kind Bush Chain is employed.
Eighteen varieties of WS Style and six forms of WAS Style Chain can be found.
(a) WS Kind Roller Chain
A WS Kind Roller Chain is made to deliver large corrosion resistance and dress in resistance for prolonged services in the severe surroundings of water treatment applications.
Since the working time of this sort of equipment is relatively quick, pins and bushings of hardened stainless steel and various components are created of exclusive alloy steel to make sure smooth bending with the chain, and superb dress in and corrosion resistance.
(b) WAS Type Bush Chain
Heat handled stainless steel provides this chain with superb overall performance for corrosion resistance and put on resistance.
BF Variety Bushing Chain for Water Remedy Drive Unit
This chain is applied to connect water remedy equipment to a energy source. During the previous, JIS/ ANSI variety roller chains have been applied. For enhanced corrosion resistance, every one of the parts are now made of 13Cr stainless steel. Because the chain is operated at a slow velocity, a bushing chain without having rollers is utilized. The sprockets are interchangeable with 
JIS/ ANSI roller chain sprockets.
We manufacture 7 kinds of BF Sort Bushing Chains within a range from 120 to 240, which include heavy-duty sort.
