Chains applied for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage remedy facilities along with other water remedy amenities demand particularly high resistance to corrosion and wear since they’re right exposed to sewage and sludge. A filth getting rid of chain is moved at a reasonably fast velocity on an almost vertically installed rail, though the operation frequency is low, so WS Variety Roller Chain is used. Conversely, a chain for raking up and/or out filth is driven at a really slow speed and does not need rollers, so WAS Kind Bush Chain is used.
Eighteen types of WS Variety and six types of WAS Style Chain can be found.
(a) WS Kind Roller Chain
A WS Form Roller Chain is built to deliver substantial corrosion resistance and wear resistance for prolonged support inside the serious atmosphere of water treatment applications.
Since the operating time of this type of equipment is comparatively quick, pins and bushings of hardened stainless steel together with other elements are made of unique alloy steel to be sure smooth bending with the chain, and fantastic wear and corrosion resistance.
(b) WAS Type Bush Chain
Heat handled 
stainless steel presents this chain with superb functionality for corrosion resistance and wear resistance.
BF Style Bushing Chain for Water Treatment Drive Unit
This chain is utilized to connect water treatment method equipment to a electrical power source. While in the past, JIS/ ANSI variety roller chains have been applied. For enhanced corrosion resistance, all the parts are now made of 13Cr stainless steel. Because the chain is operated at a slow speed, a bushing chain with out rollers is used. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture seven forms of BF Style Bushing Chains in a range from 120 to 240, such as heavy-duty form.
