(1)Features
With the EagleBurgman DRU system it is
possible to supply barrier fluid to double
and tandem mechanical seals for a broad
range of applications. Pressure boosters
are equipped as standard with all the
necessary system connections and brackets.
System components can thus be installed
to suit all requirements. The maximum
operating pressure of 63 bar applies to the
housing of the pressure booster, i.e. the
process/medium pressure at the connection
must be lower and is conditional on the
transmission ratio:
DRU2063/A001 up to 57 bar
DRU2063/A002 up to 42 bar
Circulation in accordance with API 682/
ISO 21 049: Plan 53C
(2)Advantages
• 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
• Housing is easy to dismantle: all parts are readily accessible for cleaning
• Protective pipe for piston rod made of borosilicate glass: optimum level monitoring
• Sockets with recessed gasket: no contamination of the circuit by thread sealant
• Modular system: combination with a wide range of system components possible
(3)Functional description
The function of the DRU system is similar
in principle to the TS system. The difference
is that the barrier pressure is created by the
reference pressure without any additional
superimposition of nitrogen. The pressure
booster is for storing and cooling the barrier
fluid. Pressurization is by means of a piston
in dependency on the process/medium
pressure. Automatic pressure increase in
accordance with the transmission ratio.
(4)Standards and approvals
• PED 97/23 EC (Design and production in accordance with EU Pressure Equipment Directive)
• ASME VIII, Div. 1 (Design, calculation and production)
(5)Recommended applications
• Refining technology
• Oil and gas industry
• Chemical industry
• Petrochemical industry
(6)Item Description
A Barrier medium IN (G1/2")
connection possible for SPI2063
B Barrier medium OUT (G1/2")
C Process medium (G1/2")
D Coolant IN (tube 15 x 1.5)
E Coolant OUT (tube 15 x 1.5)
F Connection for SPN (G1/8")
The DRU pressure booster must always
be installed higher than the mechanical
seal. The barrier fluid flows via the return
pipe into the vessel and is cooled. The
exchange of fluid takes place by the
thermosiphon principle or by forced
circulation, e.g. with a pumping screw.
Connection pipes to the seal should be
designed with as little resistance as
possible.
