Slide Ring Seal for Plunger GD2000P

Product catalog summary
Overview: The document describes the GD2000P slide ring seal for plungers, designed for applications requiring low friction. It features a radial pressure loading system that allows for quicker response to pressure changes compared to conventional seals.
Specifications: The seal is composed of an elastic NBR ring, a PTFE-Bronze compound slide ring, and a POM support ring. It is suitable for use with mineral oil-based media, with alternative materials available upon request for other fluids.
Materials: Standard materials include NBR, PTFE-Bronze, and POM. Alternative materials such as MPF, QVMF, and MDPE are available upon request.
Application Range: The seal is designed for single-acting piston applications with radial pressurization, suitable for use up to 360 bar.
Design Hints: The seal requires specific surface finishes for optimal performance: sliding surfaces (Ra 0.3-0.5 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 elastic ring is expanded and snapped into the groove, followed by the installation of the slide ring and the insertion of the split support ring.
Order Information: The document provides a detailed list of available dimensions for the GD2000P seal, ranging from diameters of 40 mm to 500 mm, along with corresponding reference numbers for ordering.

Gleitring-Dichtsatz für Plunger Slide Ring Seal for Plunger GD2000P Gleitring-Dichtsatz für Plunger Slide Ring Seal for Plunger Der Hunger Gleitring-Dichtsatz für Plunger GD2000P kommt bei Einsatzfällen mit Forderung nach geringer Eigenreibung zum Einsatz. Durch die radiale Druckbeaufschlagung reagiert das System schneller auf Druckanstieg als herkömmliche Dichtungen. The Hunger slide ring seal for plunger type GD2000P is used for applications where low friction is required. Due to its radial pressure loading arrangement, it reacts faster to pressure build up than conventional seals. Der Dichtsatz besteht aus einem elastischen Grundkörper aus NBR, einem Gleitring aus abriebfestem PTFE-Bronze-Compound als Dichtring und einem seitlichen Stützring aus POM. Die Standardmaterialien NBR/PTFE-Bronze/POM eignen sich bei nahezu allen Medien auf Mineralölbasis; bei Verwendung anderer Druckflüssigkeiten steht unsere Anwendungstechnik zur Verfügung. The seal consists of an elastic ring of NBR, a slide ring made of abrasion-resistant PTFE-Bronze-compound which acts as the sealing ring and a lateral POM support ring. In standard materials, NBR/PTFE-Bronze/POM, the seal is suitable for use with mineral oils. For use with other fluids, contact our application engineers for guidance. 113
