SPO (Plan 53C)

Features

Pressurized barrier system (closed circuit) for use in seal systems with high pressures and/or for hazardous/environmentally harmful processes. The SPO Plan 53C range is available with a pressure booster, cooler (finned tube, water or air cooler with fan) and a wide range of instruments.

Circulation in accordance with API 682 / ISO 21049: Plan 53C

Advantages

  • Pressurization is by means of a pressure booster
  • Automatic setting of the barrier pressure via reference pressure: simple and reliable mode of operation
  • Safe operation even in case of pressure changes
  • 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 and approvals

  • PED 2014/68/EU (Design and production in accordance with EU Pressure Equipment Directive)
  • ASME VIII, Div. 1 (Design, calculation and production)

Functional description

The SPO is designed to perform the following functions of a barrier system:
  • to pressurize the buffer chamber
  • 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 booster in dependency on the process pressure. Circulation in the barrier circuit takes place by the thermosiphon principle or by forced circulation, e.g. with a pumping screw.

Notes

A refilling unit has to be provided.
