The specification of the concrete plinth is a complete design with dimensions, reinforcement and concrete specs. It is intended for on-site construction. Xylem supplies the specs, but not the plinth.
The concrete plinth is engineered to take all static and dynamic loads, and to limit vibration and noise. The openings around the top give access to the bolts under the pump for the installation and to the service hatch in the suction bend.
Vertical, permanent, dry pump installation. The submersible pump is installed in a dry pit, with flange connection to suction and discharge piping.
