Chains made use of for collecting accumulated sediment in setting basins and sedimentation basins or getting rid of the collected sediment in sewage therapy services together with other water therapy services demand specially higher resistance to corrosion and put on since they are immediately exposed to sewage and sludge. A filth getting rid of chain is moved at a reasonably speedy pace on an pretty much vertically installed rail, however the operation frequency is reduced, so WS Variety Roller Chain is employed. Conversely, a chain for raking up and/or out filth is driven at an extremely slow velocity and will not call for rollers, so WAS Style Bush Chain is applied.
Eighteen kinds of WS Sort and 6 forms of WAS Form Chain can be found.
(a) WS Sort Roller Chain
A WS Sort Roller Chain is built to supply large corrosion resistance and dress in resistance for long service in the extreme surroundings of water remedy applications.
Because the working time of this kind of gear is comparatively quick, pins and bushings of hardened stainless steel along with other components are created of specific alloy steel to make certain smooth bending in the chain, and fantastic put on and corrosion resistance.
(b) WAS Type Bush Chain
Heat treated stainless steel supplies this chain with outstanding effectiveness for corrosion resistance and put on resistance.
BF Form Bushing Chain for Water Remedy Drive Unit
This chain is utilized to connect water remedy products to a power supply. While in the past, JIS/ ANSI style roller chains were utilized. For enhanced corrosion resistance, all the components are now manufactured of 13Cr stainless steel. Because the chain is operated at a slow velocity, a bushing chain with no rollers is applied. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 kinds of BF Type Bushing Chains in a range from 120 to 240, like heavy-duty form.
