Sewage Therapy Chain (WS or WAS Type Chain)

BF Type Bushing Chain for Water Therapy Drive Unit
This chain is applied to connect water therapy gear to a power supply. While in the past, JIS/ ANSI form roller chains have been used. For enhanced corrosion resistance, the many components are now produced of 13Cr stainless steel. Because the chain is operated at a slow velocity, a bushing chain without the need of rollers is used. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture 7 types of BF Form Bushing Chains in a vary from 120 to 240, together with heavy-duty kind.

Chains employed for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage treatment method amenities together with other water remedy amenities need particularly higher resistance to corrosion and wear considering that they’re immediately exposed to sewage and sludge. A filth getting rid of chain is moved at a reasonably fast pace on an nearly vertically put in rail, however the operation frequency is minimal, so WS Style Roller Chain is applied. Conversely, a chain for raking up and/or out grime is driven at an exceptionally slow speed and isn’t going to demand rollers, so WAS Sort Bush Chain is utilized.
Eighteen forms of WS Kind and six forms of WAS Sort Chain can be found.
(a) WS Sort Roller Chain
A WS Sort Roller Chain is built to supply large corrosion resistance and put on resistance for prolonged support within the extreme atmosphere of water therapy applications.
Since the operating time of this sort of products is relatively short, pins and bushings of hardened stainless steel along with other components are created of special alloy steel to make certain smooth bending with the chain, and excellent put on and corrosion resistance.
(b) WAS Sort Bush Chain
Heat treated stainless steel delivers this chain with fantastic performance for corrosion resistance and dress in resistance.
