Product Description

Product Description

(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

    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")

 

Operating and installation diagram for a 
DRU system.

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.
