Piston pressure booster DRU2000 series

gasnitrogenoil

Features With the EagleBurgmann DRU system it is possible to supply barrier fluid to double and tandem mechanical seals for a broad range of applications. 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 21049: Plan 53C 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 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) Recommended applications Refining technology Oil and gas industry Chemical industry Petrochemical industry 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.
