Sewage Treatment Chain (WS or WAS Variety Chain)

BF Type Bushing Chain for Water Treatment method Drive Unit
This chain is applied to connect water treatment products to a electrical power source. In the previous, JIS/ ANSI style roller chains had been employed. For enhanced corrosion resistance, the many components are now produced of 13Cr stainless steel. Because the chain is operated at a slow speed, a bushing chain without the need of rollers is employed. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 types of BF Form Bushing Chains in the vary from 120 to 240, such as heavy-duty style.

Chains utilized for collecting accumulated sediment in setting basins and sedimentation basins or getting rid of the collected sediment in sewage treatment facilities as well as other water therapy amenities require particularly high resistance to corrosion and put on considering the fact that these are straight exposed to sewage and sludge. A grime getting rid of chain is moved at a relatively quickly pace on an virtually vertically installed rail, however the operation frequency is very low, so WS Style Roller Chain is used. Conversely, a chain for raking up and/or out filth is driven at an exceptionally slow speed and doesn’t call for rollers, so WAS Form Bush Chain is used.
Eighteen varieties of WS Style and 6 types of WAS Style Chain are available.
(a) WS Sort Roller Chain
A WS Type Roller Chain is built to deliver high corrosion resistance and dress in resistance for long services in the severe setting of water treatment method applications.
Since the operating time of this type of equipment is comparatively short, pins and bushings of hardened stainless steel together with other parts are produced of special alloy steel to guarantee smooth bending of your chain, and superb wear and corrosion resistance.
(b) WAS Variety Bush Chain
Heat treated stainless steel gives this chain with exceptional efficiency for corrosion resistance and dress in resistance.
