Sewage Treatment Chain (WS or WAS Variety Chain)

BF Form Bushing Chain for Water Treatment Drive Unit
This chain is applied to connect water remedy gear to a energy supply. In the past, JIS/ ANSI style roller chains were made use of. For enhanced corrosion resistance, all of the parts are now manufactured of 13Cr stainless steel. Because the chain is operated at a slow pace, a bushing chain with no rollers is made use of. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 types of BF Style Bushing Chains in a range from 120 to 240, such as heavy-duty sort.

Chains applied for collecting accumulated sediment in setting basins and sedimentation basins or getting rid of the collected sediment in sewage treatment facilities along with other water treatment method services require specifically substantial resistance to corrosion and wear given that they can be straight exposed to sewage and sludge. A dirt getting rid of chain is moved at a rather speedy velocity on an just about vertically set up rail, even though the operation frequency is reduced, so WS Form Roller Chain is utilised. Conversely, a chain for raking up and/or out filth is driven at an exceptionally slow velocity and won’t need rollers, so WAS Style Bush Chain is employed.
Eighteen kinds of WS Type and 6 types of WAS Type Chain can be found.
(a) WS Type Roller Chain
A WS Kind Roller Chain is built to supply large corrosion resistance and put on resistance for long services from the significant surroundings of water treatment method applications.
Because the working time of this kind of equipment is comparatively quick, pins and bushings of hardened stainless steel as well as other parts are created of distinctive alloy steel to make certain smooth bending on the chain, and exceptional dress in and corrosion resistance.
(b) WAS Form Bush Chain
Heat treated stainless steel gives this chain with exceptional functionality for corrosion resistance and dress in resistance.
