PARKER KS ROTARY SEAL

    KS Rotary Seal

    Descriptions

    The Ultrathan® sealing set profile KS has been developed especially for sealing pistons in dual media hydraulic accumulators. It consits of two u-rings of different design
    and compound. The shape of the seals makes them ideal for the permanent separation of the pressurized media e.g. oil and gas with low friction forces.
    The KS can be used in other applications including industrial shock absorbers, hydropneumatic equipment such as feed and counter balance units, hydro-pneumatic
    booster or converter units, pressure transducers and operating cylinders.

    Features

    • Robust seal profile for harshest operating conditions.
    • Extreme wear resistance.
    • Assembly on one-part piston is possible.
    • High extrusion resistance.
    • Excellent media resistance in case of
    suitable compound selection.
    • Suitable compounds available for
    special requirements of the chemical
    process industry.
    • Suitable compounds available for special requirements of the food processing
    industry.
    • Dimensions according to ISO 5597.
    • Installation in closed and undercut
    housings.
    • Additional sizes of machined products
    available on short notice.

    Range of application

    Operating pressure ≤ 350 bar
    Operating temperature -30 °C to +80 °C
    Sliding speed ≤ 3 m/s
    Media Hydraulic oils based on mineral oil and gases

    Compounds
    Parker polyurethane Ultrathan® P5008 is used for the oil side seal and polyurethane
    Ultrathan
    ® P5010 is used for the gas side. When compared to commercial polyurethanes both these compounds have a superior resistance to high temperature and
    lower compression set values.
    Installation
    The performance of profile KS piston seal set is only guaranteed when the green
    colour seal (KH … P5008) is installed on the oil side of the piston and the red colour
    seal (KG … P5010) on the gas side. The general recommendations as shown in our
    hydraulics brochure are applicable to the housing groove and seal installation, e. g. no
    sharp edges, no sharp tools, clean components, etc.
