SPB6 Barrier fluid system
with bladder accumulator

Merkmale

Pressurized barrier system (closed circuit) for use in seal systems with high pressures and/or for hazardous/environmentally harmful processes. The SPB6000A4 (Plan 53B) range is available with a pressure accumulator, cooler (finned tube, water or air cooler with fan) and a wide range of instruments.
A refilling unit has to be provided.

Vorteile

  • Pressurization is by means of a pre-loaded bladder accumulator
  • The nitrogen is separated from the barrier medium by membranes in the accumulator: nitrogen cannot get into the barrier medium or process medium
  • Barrier pressure is created without any need for connection to a nitrogen supply
  • Available with finned tube, water or air coolers with fan
  • Modular system: combination with a wide range of system components/instruments possible

Standards und Freigaben

  • API 682 / ISO 21049
  • API 682 4th ed. Cat. 2/3 - 3CW-FB
  • API 682 4th ed. Cat. 2/3 - 3CW-BB
  • API 682 4th ed. Cat. 2/3 - 3CW-FF
  • API 682 4th ed. Cat. 1 - 3CW-FB
  • Compliant to TA Luft (German Clean Air Act)

Funktionsbeschreibung

The SPB6000A4 is designed to perform the following functions of a barrier system:

- To pressurize the buffer chamber
- As leakage compensation
- To cool the seal

Pressurization (> process pressure) prevents the process medium from getting into the barrier circuit or the atmosphere. Pressurization is supplied by a pressure accumulator which is pre-loaded with nitrogen. Circulation in the barrier circuit occurs via the thermosiphon principle or by forced circulation, e.g., with a pumping screw.

Hinweis

Design and production in accordance with EU Pressure Equipment Directive PED 2014/68/EU available.
