Sewage Therapy Chain (WS or WAS Form Chain)

Chains made use of for collecting accumulated sediment in setting basins and sedimentation basins or getting rid of the collected sediment in sewage remedy amenities together with other water treatment facilities require especially large resistance to corrosion and dress in due to the fact they may be directly exposed to sewage and sludge. A dirt getting rid of chain is moved at a relatively fast pace on an practically vertically installed rail, although the operation frequency is low, so WS Form Roller Chain is utilized. Conversely, a chain for raking up and/or out filth is driven at an incredibly slow speed and won’t require rollers, so WAS Style Bush Chain is used.
Eighteen sorts of WS Type and six kinds of WAS Sort Chain are available.
(a) WS Style Roller Chain
A WS Kind Roller Chain is intended to provide large corrosion resistance and dress in resistance for long services from the extreme setting of water treatment applications.
Since the working time of this type of gear is comparatively quick, pins and bushings of hardened stainless steel and various elements are produced of specific alloy steel to make certain smooth bending on the chain, and exceptional wear and corrosion resistance.
(b) WAS Kind Bush Chain
Heat treated stainless steel presents this chain with excellent performance for corrosion resistance and put on resistance.

BF Kind Bushing Chain for Water Treatment method Drive Unit
This chain is used to connect water treatment equipment to a energy supply. From the past, JIS/ ANSI type roller chains had been applied. For enhanced corrosion resistance, each of the components are now produced of 13Cr stainless steel. Because the chain is operated at a slow speed, a bushing chain without having rollers is utilised. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture seven varieties of BF Style Bushing Chains in the vary from 120 to 240, together with heavy-duty form.
