2 Circulation for cooling and filtration inlarge machineries and hydraulic systems,pumping transformer oil for insulation intransformers. Transfer onboard ships, in oil factories,refineries, tank farms dataInlet pressureMax. inlet pressure is 7 barMin. inlet pressure is shown in theSelection guideDisplacement cm3/rSize,lead 025L 025 NDisplacement cm3/r relief valveThe pump is equipped with an integralpressure relief valve with internal return,limiting the differential pressure across thepump and protecting the pump should thedischarge line be blocked.
3 The valve isadjustable for different opening value of the pressure limit can be set atthe factory and should be adjusted atinstallation (see Installation & Startupinstruction for Low pressure pumps ). Thevalve has a pressure accumulation of bar, so with moderate demands onpressure modulation, it may also be usedfor pressure regulation. The valve has amax. set pressure of 7 pump is designed to be short coupled toan electrical motor IEC size 71. The motorbearing will have to carry a slight axial loadfrom the rotor set. With motors deliveredfrom IMO AB, this load will not significantlyimpair the bearing life speed limitThe maximum speed is 3600 rpm.
4 Forhigher speeds contact IMO ACD pump is designed to operate inone rotational direction only, as standardclockwise when facing the shaft viscosity2-1500 mm2/s. For higher viscosities contactIMO temperature-20 C to 90 C for all types of levelA typical sound level from a pump withstandard driver is 58 dB(A). This value refersto free field conditions at 5 bar, 2940 rpm and40 cSt, measured according to ISO and recommendationVersion NTBP is recommended wheneverthe starting viscosity might exceed 800 otherwise specified, version IVBP will be pressureMaximum differential pressure is 7 bar but is reduced at low viscosities as shown in thetable , mm2/s (cSt)2345678910 Max.
