Filtration of bright plating solutions, is required to ensure brilliancy as well as smoothness of deposit and this can be achieved by pressure filtration. In the process of pressure frication the solution is forced filtration, suitable filter media by means of acid and alkaline resistant polypropylene pump fitted with high impact impeller.
This totally enclosed filter unit, as illustrated, consists of disc type filter elements pack, monoblock pump body and P.P. lined container mounted on the wheeled trolley. This unit is suitable for acid and alkaline solutions having temperature upto 90* C, with exception of CHROME.
The components of the filter unit, which remain in contact with acid and alkaline solutions are of rubber, plastic and stainless steel to resist the corrosion action.
