A C E 3 1122.03 G BACE3Std LineFlow volume:10 - 180 l/min Max differential pressure: 16 bar Applications: Circulation, lubrication and transferA C E 3 1122.03 G Bwww.imo.se21.1 FunctionalityThe Std Line (standard) ACE pump comes in two executions; Lube Line and Fuel Line. The main difference is the shaft seal design; (V-Seal) - optimized for light duty and (T-Seal) - heavy duty respectively.The ACE pump is used for a number of different fluids:Lubrication oil, fuel oil, vegetable oil, hydraulic oil and other hydraulic fluids, polymers, emul-sions and any non-aggressive fluid with sufficient lubricating properties.If requested, the ACE pump may be certified according to any of following classification societ-ies: DNV, BV, LRS, ABS, RS, GL, RINA, KR, NK, RMR or CCS.1.2 ApplicationsTypical applications are:- Lubrication of diesel engines, gears, gas and steam turbines, hydro turbines and paper ma-chines- Circulation for cooling and filtration in large machineries, hydraulic systems and transformer oil for insulation in transformers- As transfer pumps onboard vessels, in power plants, oil factories, refineries, tank farms etc - Fuel supply duties for engines - Supply and circulation of fuel oil1.3 InstallationThe pump is designed to be flange-mounted to its electric motor via a connecting frame and a flexible shaft coupling. By the angle bracket, the pump may be mounted horizontally or verti-cally.The ACE pump can also be mounted on valve blocks called T4 or T5.As standard, the pump is delivered including counter flanges (IMO AB design).For more information about installation, see Installation and Start-up instruction for low pres-sure pumps.A C E 3 1122.03 G Bwww.imo.se 3A C E 025N 3 N VB PPump seriesACE SizePower rotor diameter [mm]025, 032, 038LeadL and K = Low lead N = Normal lead D = High lead GenerationDesign generation 3Material in pump bodyN = Nodular cast ironShaft seal designV = Carbon/Stainless steel, elastomers in Viton (Lube Line)T = Silicon Carbide/Silicon Carbide, elastomers in Viton (Fuel Line)MountingB = Flange mountingValveP = Pressure relief valve with spring for max. 16 barSpecial designCode group omitted for standard design (A-number)A C E 3 1122.03 G Bwww.imo.se43.1 Pressure InformationPressure relief valveThe pump is equipped with an integral pressure relief valve with internal return, limiting the differential pressure across the pump and protecting the pump. Should the discharge line be blocked, the relief valve will open by the pressure.The valve is adjustable for different opening pressures. The value of the pressure limit can be set at the factory and should be adjusted at installation (see Installation & Start-up in-struction for low-pressure pumps).The maximum pressure accumulation varies with pump size, speed and viscosity, but will normally not exceed 4 bar.The valve has a maximum set pressure of 16 bar.Inlet pressureMinimum inlet pressure (suction capability) is dependent on fluid viscosity and rotation speed. It increases with decreasing viscosity and decreasing speed. Information about mini-mum inlet pressure for each individual duty case can be obtained from IMO AB or pump selection software WinPump.Maximum inlet pressure is 7 bar.Discharge pressureMaximum discharge pressure is 16 bar.Differential pressureMaximum differential pressure is 16 bar but reduced at low viscosities according to table belowViscosity [cSt] 1,4 2 6 10 >12Max. diff. pressure [bar] 6,9 8 12,4 15 16Refer to your IMO representative or use the pump selection software WinPump to determine the exact operating limits.3.2 Driver informationDriver typeThe pump is designed to be connected to an electrical motor via a flexible shaft coupling.SpeedThe maximum speed is 3600 rpm. For higher speeds, contact IMO AB.RotationThe pump is designed to operate in one rotational direction only, as standard clockwise when facing the shaft end. Pumps for CCW operation can be delivered on special request.For shorter periods of time, a few minutes for emptying a discharge line, the pump may be operated in reverse direction, provided the back pressure is limited to 3 bar.A C E 3 1122.03 G Bwww.imo.se 53.3 Sound levelTypical pump sound levels refer to free field conditions at a distance of 1 m from the pump. Noise of driver excluded in the quoted figures. The sound levels are measured at a discharge pressure of 5 bar, speed 2940 rpm and viscosity 40 cSt, according to ISO-3741.Size 025 032 038Sound level dB [A] 58 58 583.4 Moment of InertiaMoment of intertia [10-6 kgm 2]Size 025 032 038Value 49 72 1943.5 Fluid viscosityLube Line seal (Seal version code V):1,4 – 800 cSt for Lube and hydraulic oil Fuel Line seal (Seal version code T):1,4 – 3500 cSt for Fuel oilFor higher viscosity, contact IMO AB.3.6 Fluid temperatureLube Line (Seal version code V): -20 – +90 °C Fuel Line (Seal version code T): -20 – +155 °CA C E 3 1122.03 G Bwww.imo.se64.1 Ball bearingThe pump is fitted with an internal ball bearing which continously is being greased by the hand l ing media.4.2 Design materialModel Material pump Material rotor Material idler Material seal Material Elastomers ACE NV Nodular castironSteel, surface treated Cast iron, sur-face treated Carbon/Silicon carbideViton ACE NTNodular cast ironSteel, surface treatedCast iron, sur-face treatedSilicon carbide /Silicon carbideVitonA C E 3 1122.03 G Bwww.imo.se 7025L 025N rpm l/min kW l/min kW1470 10,0 0,313,5 0,4 1770 12,9 0,4 17,7 0,5 2950 24,5 0,9 34,1 1,0 3550 30,4 1,142,5 1,3032L 032Nrpm l/min kW l/min kW1470 22,8 0,535,9 0,8 1770 29,0 0,7 44,6 1,0 2950 53,3 1,3 79,0 1,9 3550 65,6 1,796,4 2,4038K 038N 038D rpm l/min kW l/min kW l/min kW1470 45,5 1,055,8 1,3 59,1 1,21770 57,1 1,3 70,5 1,7 76,2 1,52950 102,9 2,5 128,4 3,2 143,9 2,93550 126,2 3,2157,9 4,1178,2 3,6Typical performance values at 5 barFlow calculated at 26 cSt, power at 260 cSt.A C E 3 1122.03 G Bwww.imo.se8A C E 3 1122.03 G Bwww.imo.se9P o s N o D e n o m i n a t i o n1020 C o m p l e t e p o w e r r o t o r(112) B a l a n c i n g p i s t o n 113 K e y 122 B a l l b e a r i n g 125 S e c o n d a r y s e a l 125A R e t a i n i n g r i n g 202 I d l e r r o t o r 351 B a l a n c i n g b u s h 401 P u m p b o d y 440 R e t u r n v a l v e 451 S c r e wP o s N o D e n o m i n a t i o n 453 S c r e w 462 P l u g 462A S e a l i n g w a s h e r 463 P l u g 463A S e a l i n g w a s h e r 501 F r o n t c o v e r 506 G a s k e t 509 S h a f t s e a l 537 D e a e r a t i o n p l u g 537A S e a l i n g w a s h e r 551 R e a r c o v e r P o s N o D e n o m i n a t i o n556 G a s k e t557 P l u g 557A S e a l i n g w a s h e r 6000 C o m p l e t e v a l v e e l e m e n t (605) O -r i n g (608) V a l v e s p i n d l e (608A ) T e n s i o n p i n (6120) C o m p l e t e r e g u l a t i n g n u t (613) P i n (614) V a l v e p i s t o n (615) V a l v e s p r i n g7.
