Shaft Closure BL/SAP
Heavy-duty manhole and shaft sealing system for permanent or temporary containment. Circular one-piece massive 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 features a massive one-piece steel plate and an adapted counter ring. A special round seal is compressed against the shaft walls by bolting the base and counter rings together.
Universal implementation with robust bolting mechanism for industrial-grade compression.
