Item No. Description
1 Storage tank (capacity 3L)
2 Inlet filter with vented cap
3 Sight-glass or level switch
4 Name plate
5 Overflow G 1/8
  • Designed for varied applications due to
    construction in stainless steel with
    borosilicate sight-glasses suitable for
    highly corrosive media
  • Reliability in operation due to the design of
    combined filling and ventilation filter in the
    hand refill pump
  • Construction design for operating
    pressure up to 200 °C
  • Discharge of leakage is achieved due to
    integrated overflow design
  • To monitor the fluid volume a level switch
    can be installed instead of sight glass
  • Quench fluid systems are employed:
    • To absorb leakage
    • To monitor the leakage rate (e.g. through
      periodic reading of the level in the tank)
    • To lubricate and to cool the outboard
      mechanical seal in a tandem arrangement
    • To prevent icing
    • To protect against dry running
    • To stabilize the lubricating film
    • To exclude air from the media in order to prevent a reaction with oxygen in the air

  • Install the quench fluid tank approx. 1 … 2 m (3.3
    … 6.6 ft) above the mechanical seal. Install
    connection pipes to the mechanical seal with low
    flow resistance. Pipes must vent automatically in
    the direction of the tank. It is imperative that air
    pockets are prevented. The minimum filling level
    must always be above the connection socket at
    the side (in the case of the thermosiphon
  • Quench fluid systems can be operated in two
    different modes:
  • Dead-end quench (Plan 51):
    Quench fluid from an elevated tank. The
    characteristic feature of this principle is that no
    heat is dissipated by the system.
  • Circulation (Plan 52):
    Quench fluid from an elevated tank; external tank,
    pressureless; thermosiphon or forced circulation.
    In this case heat is dissipated by the circulation.
    Cooling capacity by convection is minimal,
  • Circulation in accordance with API 682 / ISO
    21049: Plan 51, Plan 52
  • Quench fluid supply system is employed for
    applications in sealing systems with a wide
    variety of operating parameters for supplying
    quench fluid to double and tandem mechanical
    seals. They act as a convenient fluid reservoir.
    The exchange of fluid takes place by the
    thermosiphon principle or by forced circulation,
    for example with a pumping screw. The
    QFS2000 stainless steel tank is equipped with
    sight-glasses for monitoring the MIN/MAX level
    and can be fastened with a lug fixture. The
    leakage overflow can be selectively discharged.
