Kaczmarek - DIAMIR DN/OD 400 (GŁADKA)

The Kaczmarek DIAMIR smooth series is a complete external sewerage system built for fast, reliable installation. Centered around a 400 mm smooth-walled PVC shaft, this range handles residential, commercial, and light industrial drainage. Every part is designed to work together, which cuts down on on-site cutting and custom fitting. The bright orange color makes pipes and fittings easy to spot during assembly, while the smooth interior keeps water flowing freely and prevents blockages.

Flexible Shaft & Manhole Configurations

Installers can pick between 2-meter and 6-meter smooth PVC shaft pipes, plus a 375 mm telescopic extension for quick depth adjustments. The system supports both standard manhole builds and custom setups. Whether you need a straight drop or a multi-level layout, the modular design adapts to ground levels and pipe gradients without extra adapters. The smooth bore reduces friction, making routine maintenance and high-pressure jetting much easier.

Junction Boxes (Kineta) & Connection Options

The series includes PP junction boxes in two main types: TYP1 through-flow and TYP2 collection. Available with 160 mm or 200 mm inlet connections, these fittings handle 180-degree straight flows or 135/225-degree branch connections. Each kineta comes with a pre-installed rubber seal for a watertight joint. The orange PP material resists corrosion and chemicals, ensuring long-term performance in wet sewer environments.

Covers, Extensions & Surface Load Ratings

Surface access is handled by a wide range of covers matched to your traffic zone. Light-duty areas use black PP covers rated A15 (1.5 tons). Heavier zones get cast iron covers in B125 (12.5 tons) or D400 (40 tons) classes. For deeper shafts, concrete conical sections and steel covers provide extra strength. The telescopic riser and rubber sleeve seals allow quick height adjustments without breaking the pipe, saving time and material waste.

Why Installers Choose the DIAMIR Smooth System

This series cuts installation time and reduces guesswork. All parts are standardized to DN/OD 400 mm, meaning fewer special orders and less on-site modification. The smooth PVC walls, sealed PP fittings, and load-rated covers create a durable, leak-proof network that meets modern drainage standards. Whether you are laying a new sewer line or upgrading an existing one, the Kaczmarek DIAMIR system delivers consistent performance, easy maintenance, and a clean, professional finish.
