Chains applied for collecting accumulated sediment in setting basins and sedimentation basins or getting rid of the collected sediment in sewage therapy services and other water treatment services demand primarily higher resistance to corrosion and dress in given that they are really straight exposed to sewage and sludge. A filth removing 
chain is moved at a reasonably quickly velocity on an virtually vertically put in rail, even though the operation frequency is lower, so WS Style Roller Chain is applied. Conversely, a chain for raking up and/or out dirt is driven at a really slow pace and isn’t going to call for rollers, so WAS Style Bush Chain is employed.
Eighteen types of WS Style and 6 sorts of WAS Form Chain are available.
(a) WS Kind Roller Chain
A WS Type Roller Chain is intended to provide large corrosion resistance and put on resistance for extended service inside the extreme natural environment of water therapy applications.
Since the working time of this sort of tools is relatively quick, pins and bushings of hardened stainless steel along with other parts are manufactured of specific alloy steel to make certain smooth bending with the chain, and exceptional put on and corrosion resistance.
(b) WAS Form Bush Chain
Heat taken care of stainless steel supplies this chain with exceptional overall performance for corrosion resistance and put on resistance.
BF Variety Bushing Chain for Water Therapy Drive Unit
This chain is made use of to connect water treatment equipment to a power source. During the previous, JIS/ ANSI style roller chains had been applied. For enhanced corrosion resistance, every one of the components are now made of 13Cr stainless steel. Since the chain is operated at a slow speed, a bushing chain with no rollers is applied. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 types of BF Type Bushing Chains in a range from 120 to 240, including heavy-duty type.
