1.5 Use of alerts and icons
This manual uses “Notes”, “Cautions”, “Warnings”, and
“Dangers” to alert you of important information and
dangerous situations. These alerts (from the least severe
to the most severe) are:
NOTE: “Notes” inform you of important additional
information.
aCAUTION: The equipment, product or surrounding
area can be damaged if the “caution” is not obeyed.
úWARNING: Personnel can be (seriously) injured, or
the equipment can be seriously damaged if the
“warning” is not obeyed.
c DANGER: Personnel can be seriously injured
(resulting in death) if the “danger” is not obeyed.
c DANGER/WARNING: Dangers or Warnings that refer
to the use of the system in potentially explosive
atmosphere – in accordance with the ATEX
Directive 2014/34/EU.
The above icons are the general icons that are used for
“Cautions”, “Warnings”, and “Dangers”. More specic
icons are also used, depending on the type of hazard.
Refer to the following example:
úWARNING – HIGH PRESSURE: The accumulator can
burst if it is over pressurized. Fill the accumulator
slowly; check the pressure gauge regularly.

2 Safety
2.1 682-53B hazards
The following hazards can be present in the 682-53B
system:
• High pressure
• Explosion
• Dangerous chemicals/media
• Temperature (hot surfaces)
• Nitrogen (N2) in the accumulator
• Dangerous moving parts (during installation)
If the 682-53B system has any external leaks, you must
stop the system immediately and have the leak repaired
by qualied personnel.
2.2 General safety
When installing, operating and maintaining the system,
pay particular attention to safety:
• Obey all applicable safety laws and regulations.
• Obey all plant regulations.
• Make sure that only trained and qualied personnel
work on the system. Refer to section 2.3.
• Read and understand each part of this manual.
• Follow the installation, maintenance and operating
procedures exactly.
• Wear the relevant personal protective equipment (PPE).
Refer to section 2.4.
• Never work alone.
• Make sure that adequate safety equipment is installed
in and around the work area: rst aid kits, safety
showers (if applicable), re extinguishers, escape
routes, shut-off valves, etc.
• Make sure that personnel are fully trained on how to
use the safety equipment. A qualied rst aid specialist
must always be available for each shift.
• Read the plant requirements for handling hazardous
materials.
• Check MSDS for relevant information.
2.3 Trained and qualified personnel
Qualied personnel are people who have been authorized
by those responsible for the safety of the Plant to perform
the necessary work, and who can recognize and avoid
possible dangers. The following aspects determine the
qualication of personnel:
• Appropriate training
• Relevant experience
• Knowledge of relevant standards and specications
• Knowledge of accident prevention regulations
• Knowledge of plant regulations and operating conditions

2.4 Personal protective equipment (PPE)
The 682-53B is often used for applications containing
high-pressure, dangerous and/or toxic chemicals. When
operating or maintaining this system, make sure you wear
the appropriate PPE: protective clothing, gloves, safety
glasses, etc.
Always follow local regulations regarding PPE.
If one (or more) of the below icons is shown in the work
place, the equipment must be worn at all time.
When operating outside, PPE to be worn to prevent slip,

3 Environmental Considerations
aCAUTION: You are required by law to dispose
of waste products and end of life equipment,
according to local regulations.
3.1 Disposing of waste products
Any waste products resulting from the use or maintenance
of the 682-53B must be disposed of according to local
environment laws and regulations.
3.2 End-of-life equipment
úWARNING – DANGER CHEMICALS: Dangerous
chemical might be released during removal of the

682-53B System
4 Design Overview
4.1 Purpose of 682-53B
• Prevents a dual pressurized seal from leaking process
media to atmosphere by circulating a pressurized
barrier uid over the mechanical seal.
• A bladder accumulator is applied to isolate the nitrogen
from the barrier uid and establish a higher pressure
than in the seal chamber.
• Regulate the temperature of the barrier uid by
including a heat exchanger with water or air.
• Monitors the performance of the mechanical seal by
measuring (optionally) pressure, temperature, ow and
rell time.
• Lubricate the seal faces.
4.2 Typical 682-53B installations
This section describes typical 682-53B installations. The
exact system design and (optional) components can
vary depending on the options selected. For detailed
information on the 682-53B installation, refer to the GA
drawing(s) in the appendix.

4.4 Parts
Number Part Function
1 Bladder accumulator Stores energy, contains pressurized barrier uid for lubricating and cooling a
pressurized dual mechanical seal
2 Seal cooler
Used for cooling the uid. Three types are available: water cooler, nned tube/
pipe and forced draft air (size depends on the operating conditions). The cooler
can be installed separately if there is insufcient space
3 Pressure transmitter (PT) Used for pressure alarm and monitoring the pressure
4 Block and bleed valve Used to isolate pressure transmitter and vent transmitter side
5 Drain valve Used for draining the system
6 Vent valve Used for venting the system
7 Instrument valve Used for isolating the instrumentation from barrier pressure
8 Block valve Used for closing off the ll inlet line
9 Non-return valve To prevent a backow when opening the block valve
10 Y-strainer Remove solids from barrier uid during lling
