Overview

The document details the GPD rubber sealing system designed for reliable, quick sealing of cables and pipes in construction and distribution networks such as electricity, gas, and water. It supports both high and low construction applications including drilled walls, embedded pipes, and bayonet cable systems.

Product Description and Functionality

The GPD system uses rubber seals compressed by hexagonal nuts to ensure durable, gas- and water-tight sealing under pressure. Metal parts are made from A2 stainless steel (A4 optional), and sealing elements are primarily EPDM rubber, with alternatives like NBR, EPDM-silicone (for potable water), or FPM available on request.

Advantages

• Customizable for specific applications
• Gas and water tightness up to 10 bar pressure
• Retrofit capability after installation
• Short installation time
• Sound insulation
• Rodent protection

Seal Variants and Applications

Closed Seals

Used for protection against non-pressurized and pressurized water. Single-layer seals suit non-pressurized water (tightness up to 1.5 bar), double-layer seals for pressurized water (up to 5 bar). Installation only during initial construction.

Split Seals

Allow installation after cable or pipe placement, suitable for both non-pressurized and pressurized water protection, facilitating easier mounting in complex setups.

Interchangeable Inserts

Enable flexible sealing regardless of pipe occupancy. Inserts can be replaced to adjust cable or pipe occupancy without removing the entire seal.

Product Nomenclature and Ordering

Detailed ordering codes cover various seal types (closed, split, single/double-layer, with inserts, with flanges). Parameters include outer seal diameter, inner diameter of drilled hole or embedded pipe, number and diameter of cables or pipes.

Maximum Occupancy and Dimensions

Tables specify maximum cable/pipe diameters and quantities for different GPD seal outer diameters, including versions with interchangeable inserts, ensuring correct sizing for installation needs.

Embedded Pipes for Penetrations

Embedded pipes are supplied per wall thickness and concreted into formwork. Special versions exist for fiber cement and alloy steel pipes, with fixed and flexible flanges compliant with DIN 18195 part 9.

• Plastic pipes with central flange (60–500 mm diameter)
• Alloy steel pipes with welded central flange (60–1500 mm diameter)
• Fiber cement pipes with labyrinth rings, asbestos-free (80–1500 mm diameter)

Additional flange options include fixed/flexible and split flanges for retrofitting, allowing sealing before walls or ceilings.

Material and Pipe Types

The document lists pipe materials and standards such as copper, steel with plastic coatings, PE, PVC, with corresponding DIN/EN standards and nominal diameters.

Installation and Quality Assurance

Replacement parts are provided only for defects due to material faults, excluding damage from transport, storage, or improper installation. The system complies with current technical guidelines, with technical changes reserved. Proper installation instructions must be followed for all UGA products.

Additional Document Note

A brief section titled "unanji premer cevi" addresses pipe external diameters but contains minimal information and an explicit disclaimer that all data is provided without warranty or guarantee.

Key takeaway: The document primarily serves as a technical overview of the GPD sealing system with detailed product specifications, installation guidelines, and ordering information, while the pipe diameter section is limited and non-committal regarding data reliability.
