Chains used for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage remedy facilities along with other water therapy services demand primarily higher resistance to corrosion and dress in due to the fact they can be right exposed to sewage and sludge. A dirt getting rid of chain is moved at a rather rapid velocity on an nearly vertically installed rail, however the operation frequency is very low, so WS Sort Roller Chain is applied. Conversely, a chain for raking up and/or out filth is driven at a very slow velocity and will not demand rollers, so WAS Form Bush Chain is utilised.
Eighteen forms of WS Kind and six sorts of WAS Type Chain are available.
(a) WS Kind Roller Chain
A WS Variety Roller Chain is intended to 
supply large corrosion resistance and wear resistance for lengthy service during the extreme surroundings of water treatment method applications.
Because the working time of this type of products is relatively quick, pins and bushings of hardened stainless steel as well as other parts are created of distinctive alloy steel to ensure smooth bending with the chain, and excellent dress in and corrosion resistance.
(b) WAS Type Bush Chain
Heat handled stainless steel presents this chain with outstanding functionality for corrosion resistance and put on resistance.
BF Variety Bushing Chain for Water Treatment method Drive Unit
This chain is used to connect water treatment products to a energy supply. While in the past, JIS/ ANSI type roller chains have been employed. For enhanced corrosion resistance, all the parts are now made of 13Cr stainless steel. Since the chain is operated at a slow speed, a bushing chain without rollers is made use of. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 kinds of BF Variety Bushing Chains in the range from 120 to 240, which include heavy-duty type.
