1.1 Functionality
The 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 Applications
Typical 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 oil
1.3 Installation
The 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.

3. Technical Data
3.1 Pressure Information
Pressure relief valve
The 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 pressure
Minimum 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 pressure
Maximum discharge pressure is 16 bar.
Differential pressure
Maximum 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 information
Driver type
The pump is designed to be connected to an electrical motor via a flexible shaft coupling.
Speed
The maximum speed is 3600 rpm. For higher speeds, contact IMO AB.
Rotation
The 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.

3.3 Sound level
Typical 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 58
