Chains applied for collecting accumulated sediment in setting basins and sedimentation basins or getting rid of the collected sediment in sewage treatment method facilities along with other water therapy facilities demand especially substantial resistance to corrosion and put on because they’re immediately exposed to sewage and sludge. A dirt removing chain is moved at a reasonably rapid speed on an virtually vertically installed rail, however the operation frequency is minimal, so WS Style Roller Chain is made use of. Conversely, a chain for raking up and/or out grime is driven at a very slow pace and does not require rollers, so WAS Form Bush Chain is utilized.
Eighteen types of WS Kind and 6 sorts of WAS Type Chain are available.
(a) WS Style Roller Chain
A WS Form Roller Chain is intended to supply high corrosion resistance and put on resistance for prolonged support during the serious atmosphere of water treatment method applications.
Because the operating time of this type of products is relatively quick, pins and bushings of hardened stainless steel and also other elements are created of specific alloy steel to be sure smooth bending from the chain, and superb put on and corrosion resistance.
(b) WAS Type Bush Chain
Heat treated stainless steel offers this chain with exceptional functionality for corrosion resistance and dress in resistance.

BF Kind Bushing Chain for Water Therapy Drive Unit
This chain is utilized to connect water remedy products to a electrical power source. Within the previous, JIS/ ANSI style roller chains had been used. For enhanced corrosion resistance, each of the components are now made of 13Cr stainless steel. Because the chain is operated at a slow velocity, a bushing chain with no rollers is used. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture seven kinds of BF Type Bushing Chains in a vary from 120 to 240, which include heavy-duty style.
