Chains made use of for collecting accumulated sediment in setting basins and sedimentation basins or getting rid of the collected sediment in sewage treatment method services and other water remedy facilities require particularly high resistance to corrosion and put on since they can be straight exposed to sewage and sludge. A dirt removing chain is moved at a comparatively quick speed on an virtually vertically set up rail, though the operation frequency is low, so WS Style Roller Chain is applied. Conversely, a chain for raking up and/or out dirt is driven at an incredibly slow velocity and does not call for rollers, so WAS Type Bush Chain is made use of.
Eighteen varieties of WS Sort and six kinds of WAS Type Chain are available.
(a) WS Sort Roller Chain
A WS Form Roller Chain is made to supply substantial corrosion resistance and dress in resistance for prolonged service within the extreme setting of water treatment method applications.
Since the working time of this sort of products is relatively brief, pins and bushings of hardened stainless steel and various elements are created of unique alloy steel to make certain smooth bending in the chain, and outstanding put on and corrosion resistance.
(b) WAS Kind Bush Chain
Heat treated stainless steel offers this chain with great performance for corrosion resistance and wear resistance.

BF Form Bushing Chain for Water Treatment Drive Unit
This chain is made use of to connect water treatment equipment to a power source. While in the previous, JIS/ ANSI type roller chains were utilized. 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 the need of rollers is employed. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 types of BF Style Bushing Chains in the vary from 120 to 240, which include heavy-duty style.
