Chains made use of for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage remedy facilities and also other water treatment services call for specifically large resistance to corrosion and put on considering the fact that they can be directly exposed to sewage and sludge. A filth getting rid of chain is moved at a relatively speedy speed on an virtually vertically put in rail, however the operation frequency is very low, so WS Type Roller Chain is utilised. Conversely, a chain for raking up and/or out grime is driven at a very slow speed and isn’t going to call for rollers, so WAS Kind Bush Chain is employed.
Eighteen kinds of WS Form and 6 forms of WAS Variety Chain can be found.
(a) WS Sort Roller Chain
A WS Variety Roller Chain is intended to deliver large corrosion resistance and put on resistance for prolonged support from the extreme environment of water remedy applications.
Since the operating time of this type of tools is comparatively quick, pins and bushings of hardened stainless steel and also other elements are made of exclusive alloy steel to be sure smooth bending in the chain, and outstanding wear and corrosion resistance.
(b) WAS Kind Bush Chain
Heat handled stainless steel presents this chain with outstanding effectiveness for corrosion resistance and put on resistance.

BF Type Bushing Chain for Water Treatment method Drive Unit
This chain is used to connect water remedy products to a electrical power source. Within the past, JIS/ ANSI kind roller chains have been made use of. For enhanced corrosion resistance, the many elements are now made of 13Cr stainless steel. Since the chain is operated at a slow pace, a bushing chain without rollers is utilized. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 forms of BF Type Bushing Chains inside a range from 120 to 240, together with heavy-duty sort.
