Double-walled pump sumps

Mechanical anchored thermoplastic system

Double-walled BEKAPLAST pump sumps made of thermoplastic are specially designed for use in secondary containments and plants for handling water-polluting substances in accordance with AwSV.

Prefabricated pump sumps with TÜV certificate

Double-walled BEKAPLAST pump sumps with German type approval for use in "LAU-Anlagen" (plants for storage, filling and handling)
For new construction and refurbishments - suitable for the lowest point of the lining at "High" stress level according to TRwS 786
Steuler BEKAPLAST double-wall pump sumps consist of a primary and a secondary plate. The design means that a leakage gap is created between these plates, which can be checked by vacuum or with a leakage tube.
With vacuum monitoring, the requirements according to AwSV §2 Section 17 for "double-walled plants" are fulfilled.
Steuler BEKAPLAST double-wall pump sumps are resistant according to media list 40-1.1 of the Deutsches Institut für Bautechnik (DIBt Berlin).
Media-resistant connection to the BEKAPLAST trench system with technical approval Z-59.21-435 (DIBt Berlin) by certified welders in accordance with DVS leaflets/guidelines
Connection of pump sumps and trenches to lining systems or combined linings on adjacent surfaces via glas-fiber functionalised plate material as per AGI-Detail.

Steuler BEKAPLAST pump sumps and trench systems - sophisticated engineering for thermoplastic lining systems.

Advice, delivery and - if required - complete installation from a single source. And because we see the bigger picture, the perfect connection to the protective systems on the adjacent conductive areas is always included in the package.

The illustrations below represent only a selection of possible detailed designs. The actual design is always determined on a project-by-project basis depending on the specific conditions.
