PP plastic cover bottom dn 315mm, for manhole with sedimenter inside corrugated riser pipe dn 315mm, without gasket, black color (Diamir 315) 2539911090

Sewer manholes – reliable solutions for wastewater drainage systems

The PP bottom cover dn 315mm is an element of the Diamir sewer manhole system, designed for the construction of gravity sewer networks for various purposes – sanitary, rainwater, combined, industrial, and drainage. Made of polypropylene (PP), it provides a solid and durable closure for manholes with a settling tank, mounted from inside the corrugated trunk pipe dn 315mm. This bottom is dedicated to corrugated RWK pipes with a diameter of 315 mm.

Design and application

The cover functions as the bottom of the manhole, ensuring the stability and tightness of the connection. This is particularly important in places where sediment or rainwater accumulates. The lack of a gasket in the standard equipment allows for flexible adaptation to specific installation conditions – the gasket can be purchased separately, depending on the needs and requirements of the project. The use of plastic provides resistance to corrosion and aggressive chemical substances, guaranteeing long-term operation even in harsh environmental conditions.

Advantages and benefits

• Durability and resistance: Polypropylene is characterized by high resistance to abrasion, impact, and the action of chemical substances present in wastewater.
• Lightweight: Compared to traditional materials (e.g., concrete), the PP cover is much lighter, making it easier to transport and install.
• Flexibility: The possibility of using a gasket locked in the socket or oil-resistant gasket allows adaptation to specific installation requirements.
• Compatibility: Designed to work with corrugated trunk pipes dn 315mm, ensuring easy and secure installation.
• Wide range of applications: Ideal for both the construction of new sewer networks and the modernization of existing installations.
• Simple installation: The cover installation is intuitive and does not require specialized tools or skills. This means time and labor cost savings for the installer.
• Weather resistance: PP plastic is resistant to UV radiation and low temperatures, ensuring reliability even in extreme weather conditions.
• Documentation support: National Declarations of Performance are available for the Diamir system elements, confirming compliance with applicable standards and quality standards.

The PP bottom dn 315mm is a practical solution for professionals and end customers looking for a reliable element for the construction or modernization of sewer systems. It provides safety, durability and ease of installation – all at a competitive price.
