GDSI

Product catalog summary

Overview: The document provides technical specifications and installation guidelines for the GDSI Slide Ring Seal, a heavy-duty sealing solution designed for challenging conditions. It highlights the seal's capabilities, materials, application range, and fitting instructions.

Specifications: The GDSI seal is suitable for high-pressure applications up to 800 bar with reduced extrusion gaps (≤ 0.05 mm). It is compatible with installation grooves per DIN ISO 7425-1 standards. The seal offers improved sealing efficiency, service life, and dirt tolerance compared to the GODI model.

Materials: The seal is made from standard NBR, E-PTFE, and bronze, with alternative materials available upon request, including MPF, QVMF, and MDPE.

Application Range: The GDSI is designed for low friction sealing in heavy-duty applications, suitable for hydraulic oils, water-oil emulsions, and water-glycol fluids. It operates effectively within a temperature range of -35°C to +100°C and a sliding speed of up to 1 m/s.

Design Hints and Surface Finish: The document provides detailed surface quality requirements, including sliding surfaces (Ra 0.1-0.3 µm, Rt ≤ 1.5 µm), groove base (Ra ≤ 0.8 µm, Rt ≤ 3.6 µm), and groove sides (Ra ≤ 2.3 µm, Rt ≤ 15 µm).

Fitting Instructions: The slide ring is expanded over the rod, and the O-ring is inserted into the groove without twisting. The slide ring is then bent into a kidney shape and placed onto the O-ring.

Order Information: The document includes a design table with dimensions and reference numbers for ordering standard versions, ranging from diameters of 15 mm to 900 mm.

Gleitring-O-Ring-Dichtsatz, innendichtend Slide Ring Seal, inside sealing Schwere Baureihe / heavy duty series Gleitring-O-Ring-Dichtsatz, innendichtend, schwere Baureihe Slide Ring Seal, inside sealing heavy duty series Der Hunger Gleitring-O-Ring-Dichtsatz GDSI eignet sich besonders für erschwerte, rauhe Einsatzbedingungen. The Hunger slide ring seal type GDSI is particularly suitable for applications operating under difficult and onerous conditions. Bei reduziertem Passungsspiel (Spaltmaß ≤ 0,05 mm) sind Betriebsdrücke bis 800 bar möglich. Das Wirkprinzip ist gleich dem GODI, jedoch sind Dichtwirkung, Standzeiten sowie die Fähigkeit, Schmutzpartikel einzulagern, höher. Der GDSI ist auch für Einbauräume nach DIN ISO 7425-1 geeignet. With reduced extrusion gaps (gap size ≤ 0.05 mm), pressures up to 800 bar are possible . The sealing function is the same as with the GODI, however, the sealing efficiency, service life and dirt tolerance are better. The GDSI is also suitable for installation grooves in accordance with DIN ISO 74
