Sewage Treatment method Chain (WS or WAS Sort Chain)

Chains applied for collecting accumulated sediment in setting basins and sedimentation basins or getting rid of the collected sediment in sewage treatment services and various water treatment method facilities need particularly high resistance to corrosion and put on considering the fact that these are straight exposed to sewage and sludge. A dirt removing chain is moved at a reasonably fast speed on an virtually vertically set up rail, though the operation frequency is reduced, so WS Style Roller Chain is made use of. Conversely, a chain for raking up and/or out grime is driven at an extremely slow velocity and doesn’t demand rollers, so WAS Kind Bush Chain is applied.
Eighteen kinds of WS Variety and six types of WAS Kind Chain can be found.
(a) WS Kind Roller Chain
A WS Form Roller Chain is made to provide large corrosion resistance and put on resistance for prolonged service inside the extreme setting of water treatment method applications.
Since the operating time of this type of products is relatively brief, pins and bushings of hardened stainless steel and various parts are manufactured of particular alloy steel to make sure smooth bending in the chain, and superb put on and corrosion resistance.
(b) WAS Type Bush Chain
Heat treated stainless steel gives this chain with great overall performance for corrosion resistance and wear resistance.

BF Style Bushing Chain for Water Therapy Drive Unit
This chain is applied to connect water treatment gear to a power source. While in the previous, JIS/ ANSI kind roller chains were employed. For enhanced corrosion resistance, every one of the elements are now made of 13Cr stainless steel. Since the chain is operated at a slow velocity, a bushing chain without rollers is utilised. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture seven kinds of BF Form Bushing Chains in the vary from 120 to 240, together with heavy-duty type.
