BF Type Bushing Chain for Water Treatment Drive Unit
This chain is utilized to connect water treatment tools to a electrical power supply. Inside the past, JIS/ ANSI type roller chains had been used. For enhanced corrosion resistance, all the elements are now produced of 13Cr stainless steel. Since the chain is operated at a slow speed, a bushing chain devoid of rollers is applied. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture seven sorts of BF Form Bushing Chains in a vary from 120 to 240, such as heavy-duty form.

Chains used for collecting accumulated sediment in setting basins and sedimentation basins or getting rid of the collected sediment in sewage treatment facilities and other water therapy facilities demand particularly higher resistance to corrosion and put on considering that these are directly exposed to sewage and sludge. A grime getting rid of chain is moved at a reasonably rapid speed on an almost vertically set up rail, even though the operation frequency is reduced, so WS Sort Roller Chain is applied. Conversely, a chain for raking up and/or out filth is driven at an incredibly slow pace and doesn’t need rollers, so WAS Kind Bush Chain is employed.
Eighteen kinds of WS Kind and six forms of WAS Type Chain are available.
(a) WS Sort Roller Chain
A WS Kind Roller Chain is made to deliver large corrosion resistance and wear resistance for prolonged support inside the severe surroundings of water therapy applications.
Since the operating time of this sort of gear is relatively short, pins and bushings of hardened stainless steel and other components are manufactured of special alloy steel to make certain smooth bending of your chain, and exceptional dress in and corrosion resistance.
(b) WAS Sort Bush Chain
Heat handled stainless steel gives this chain with superb performance for corrosion resistance and put on resistance.
