Polyethylene manhole 7600058500

Product overview
A compact, leak‑tight energy‑dissipating manhole designed to reduce high flow velocities in sewer and stormwater systems. The unit accepts tangential inflow and guides the flow along the circular base toward the outlet, dissipating hydraulic energy to limit erosion and downstream overload. Available in nominal diameters DN 800 and DN 1000 and in multiple heights up to 5 m. When installed with a suitable manhole cover, the unit is compatible with traffic areas.

Key features

• Energy dissipation via tangential inflow and controlled circular flow along the manhole base
• Compact, leak‑tight construction suitable for constrained installation sites
• Installation‑friendly design for straightforward connection and assembly
• Prepared for connection to PVC, PE, ribbed and other common pipe systems

Outlet / connection options

• Outlet with PE pipe and sliding coupling
• Outlet with coupling for ribbed pipe systems
