Flexible Discs

We offer a range of Flexible Discs designed for progressive cavity pumps. These discs act as shock absorbers, positioned between the gear motor and the mixing shaft that connects to the rotor stator.

Each product description clearly states the specific self-leveling screed pump the disc is compatible with. Additionally, every disc is marked with its product code for easy identification and selection.

    Flexible Discs for Screed Pumps made by SGF

    Flexible discs are essential components in progressive cavity pumps and self-leveling screed machines, ensuring smooth torque transmission while protecting your equipment from shock loads and vibration.

    Installed between the gear motor and the mixing shaft connected to the rotor stator, these discs act as elastic couplings, reducing wear and extending the service life of your entire drive system.

    Our range includes high-quality flexible discs (Hardy discs) compatible with leading screed pump brands such as Putzmeister and Brinkmann. Each product is clearly labeled for quick and reliable selection.

    What Are Flexible Discs?

    Flexible discs (also known as Hardy discs or flexible couplings) are torsionally flexible drive elements that transmit torque while absorbing dynamic loads. Their design combines elastomer materials with reinforced fiber layers, allowing them to dampen vibrations and compensate for misalignment in demanding pump systems.

    Key Advantages of Flexible Discs

    • Shock absorption: Protects gear motors and drive components from torque peaks
    • Vibration damping: Reduces noise and mechanical stress
    • Misalignment compensation: Handles axial, radial, and angular deviations
    • Durable construction: Reinforced materials ensure long service life
    • Maintenance-free: No lubrication required

    These properties make flexible discs ideal for heavy-duty construction applications, especially in screed pumps operating under continuous load.

    Applications in Screed Pumps

    In self-leveling screed pumps, flexible discs play a critical role by:

    • Stabilizing torque transmission between motor and rotor-stator system
    • Preventing damage caused by sudden load changes
    • Improving operational smoothness and efficiency

    This results in reduced downtime and lower maintenance costs on-site.

    Product Compatibility & Selection

    To simplify ordering, each flexible disc in this collection includes:

    • Clear compatibility with specific machine models
    • Technical specifications (dimensions, torque capacity)
    • Unique product codes for fast identification

    This ensures you can quickly find the correct replacement part for your equipment.

    Frequently Asked Questions About SGF Flexible Discs

    What does a flexible disc do in a screed pump?

    It transmits torque while absorbing shocks and vibrations, protecting the drive system.

    Are flexible discs universal?

    No, they are machine-specific. Always check compatibility with your pump model.

    When should I replace a flexible disc?

    If you notice cracks, deformation, or increased vibration/noise during operation.

    Who is the manufacturer of the Flexible Discs?

    The German Company SGF - Süddeutsche Gelenkscheiben Fabrik.
