Sewage Therapy Chain (WS or WAS Form Chain)

Chains applied for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage therapy facilities and other water remedy amenities require specially substantial resistance to corrosion and put on since they may be immediately exposed to sewage and sludge. A grime removing chain is moved at a fairly rapidly pace on an pretty much vertically set up rail, however the operation frequency is very low, so WS Style Roller Chain is used. Conversely, a chain for raking up and/or out grime is driven at an extremely slow velocity and won’t require rollers, so WAS Variety Bush Chain is used.
Eighteen forms of WS Type and 6 forms of WAS Type Chain are available.
(a) WS Type Roller Chain
A WS Form Roller Chain is intended to provide large corrosion resistance and dress in resistance for lengthy service inside the significant surroundings of water treatment applications.
Because the working time of this sort of gear is comparatively brief, pins and bushings of hardened stainless steel and other elements are created of specific alloy steel to guarantee smooth bending with the chain, and exceptional dress in and corrosion resistance.
(b) WAS Type Bush Chain
Heat taken care of stainless steel delivers this chain with outstanding performance for corrosion resistance and dress in resistance.

BF Sort Bushing Chain for Water Treatment Drive Unit
This chain is utilized to connect water therapy equipment to a power supply. During the past, JIS/ ANSI variety roller chains have been made use of. For enhanced corrosion resistance, all the components are now produced of 13Cr stainless steel. Since the chain is operated at a slow pace, a bushing chain without the need of rollers is applied. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture seven kinds of BF Type Bushing Chains within a range from 120 to 240, such as heavy-duty sort.
