Asbestos gland packing PAFS
PAFS, woven, polypropylene with an asbestos core, impregnated with a suspension of fluoroplastic with mica.
Application:
PAFS is used in stuffing box seals of plunger pumps working with media: butyl alcohols, ammonium carbonates, at pressures up to 32 MPa, temperatures no higher than +160°C and sliding speeds up to 5 m/s. Centrifugal pumps operating with fluorosilicic acid at pressures up to 0.15 MPa and temperatures no higher than +70°С, sliding speed up to 15 m/s.
Characteristics:
Density, g/cm3: 1.0
pH of the working environment: 0-14
