Sewage Therapy Chain (WS or WAS Style Chain)

BF Type Bushing Chain for Water Therapy Drive Unit
This chain is applied to connect water treatment equipment to a electrical power source. While in the previous, JIS/ ANSI variety roller chains have been employed. For enhanced corrosion resistance, all of the elements are now manufactured of 13Cr stainless steel. Since the chain is operated at a slow speed, a bushing chain with no rollers is utilised. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 sorts of BF Style Bushing Chains inside a range from 120 to 240, which include heavy-duty sort.

Chains utilised for collecting accumulated sediment in setting basins and sedimentation basins or getting rid of the collected sediment in sewage therapy services together with other water treatment services demand specifically high resistance to corrosion and dress in since they are immediately exposed to sewage and sludge. A dirt getting rid of chain is moved at a comparatively quickly velocity on an virtually vertically set up rail, even though the operation frequency is very low, so WS Form Roller Chain is utilized. Conversely, a chain for raking up and/or out filth is driven at a very slow velocity and won’t require rollers, so WAS Sort Bush Chain is applied.
Eighteen kinds of WS Style and six sorts of WAS Sort Chain are available.
(a) WS Type Roller Chain
A WS Form Roller Chain is designed to deliver higher corrosion resistance and wear resistance for extended support during the significant natural environment of water therapy applications.
Because the working time of this kind of tools is comparatively quick, pins and bushings of hardened stainless steel and various elements are manufactured of unique alloy steel to make certain smooth bending in the chain, and excellent dress in and corrosion resistance.
(b) WAS Form Bush Chain
Heat treated stainless steel delivers this chain with fantastic performance for corrosion resistance and wear resistance.
