Shaft Closure BL/SAP
Heavy-duty manhole and shaft sealing system for permanent or temporary containment applications. Features a robust one-piece circular steel design.
INTERNAL SHAFT SEALING SYSTEM
The BL/SAP is designed for crack-free circular channel inflows, overflows, or installation shafts. It is suitable for both horizontal and vertical implementation.
The closure element consists of a one-piece steel plate and a matching counter ring. A specialized circular seal is compressed against the shaft walls by bolting the base plate and counter ring together.
Universal implementation with robust bolting mechanism for industrial-grade compression.
