SPO (Plan 53C)

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.

Technical informations

• - 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

 

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.
