BF Form Bushing Chain for Water Remedy Drive Unit
This chain is used to connect water therapy tools to a electrical power supply. During the previous, JIS/ ANSI form roller chains were used. For enhanced corrosion resistance, the many parts are now made of 13Cr stainless steel. Since the chain is operated at a slow pace, a bushing chain without rollers is employed. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 sorts of BF Form Bushing Chains in the range from 120 to 240, like heavy-duty variety.

Chains applied for collecting accumulated sediment in setting basins and sedimentation basins or getting rid of the collected sediment in sewage treatment method services together with other water treatment services call for in particular higher resistance to corrosion and wear because they’re directly exposed to sewage and sludge. A grime removing chain is moved at a rather fast pace on an pretty much vertically put in rail, though the operation frequency is reduced, so WS Kind Roller Chain is used. Conversely, a chain for raking up and/or out grime is driven at an exceptionally slow velocity and will not require rollers, so WAS Type Bush Chain is utilised.
Eighteen kinds of WS Kind and six forms of WAS Type Chain are available.
(a) WS Type Roller Chain
A WS Form Roller Chain is made to supply large corrosion resistance and wear resistance for prolonged service during the severe surroundings of water treatment applications.
Since the operating time of this sort of gear is comparatively short, pins and bushings of hardened stainless steel together with other components are created of exclusive alloy steel to ensure smooth bending in the chain, and great put on and corrosion resistance.
(b) WAS Form Bush Chain
Heat treated stainless steel provides this chain with great functionality for corrosion resistance and put on resistance.
