An optional feature for both (CVSL & CVDL) series is a “wear sleeve” passing through the orifice of the diaphragm.
The Sleeve will carry the material (e.g. powders, granules etc.) without direct contact with the diaphragm.
This feature helps to enhance the life of the diaphragm and the product safety.
Guide/ Wear Sleeves are available in Silicon Rubber in sizes from 100mm to 200mm & in PU Coated Polyester in sizes from 100mm to 450mm.
