1.1 FunctionalityThe Std Line (standard) ACG pumps come in two executions; Lube Line and Fuel Line. The maindifference is the shaft seal design, optimized for light duty and heavy duty respectively.
The ACG pumps are used for a number of different uids:Lubrication oil, fuel oil, vegetable oil, hydraulic oil and other hydraulic uids, polymers, emul-sions and any non-aggressive uid with sufcient lubricating properties.If requested, the ACG pump may be certied according to any of following classication 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 ltration in large machineries, hydraulic systems and transformeroil for insulation in transformers- As transfer pumps onboard vessels, in power plants, oil factories, reneries, tank farms etc- For supply and circulation systems
1.3 InstallationThe pump is designed to be ange-mounted to its electric motor via a connecting frame and aexible shaft coupling. By the angle bracket, the pump might be mounted horizontally or verti-cally.
As standard, the pump is supplied without counter anges (DIN type) but they can be includedif requested.
As standard the pump is delivered with the discharge side to the right when seen from thepump shaft side(see below).
For more information about installation, see Installation and Start-up instruction for low pres-sure pumps.
Mounting standard picture M93-0.
On request the pump can be delivered in the opposite direction, M39-0.

3. Technical Data
3.1 Pressure Information
Pressure relief valve
The pump is equipped with an integral pressure relief valve with internal return, limitingthe differential pressure across the pump and protecting the pump. Should the dischargeline be blocked, the relief valve will open by the pressure.The valve is adjustable for different opening pressures. The value of the pressure limit canbe 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 willnormally not exceed 4 bar.
The valve has a maximum set pressure of 16 bar.
Inlet pressure
Minimum inlet pressure (suction capability) is dependent on uid viscosity and rotationspeed. 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 pumpselection software WinPump.
Maximum inlet pressure is 12 bar.
Discharge pressure
Maximum discharge pressure is 16 bar.
Differential pressure
Maximum differential pressure is 16 bar but reduced at low viscosities according to tablebelow
Viscosity [cSt] 1,4 2 6 10 >12Max. diff. pressure [bar] 6,9 8,0 12,4 15 16Refer to your IMO representative or use the pump selection software WinPump to determinethe exact operating limits.
3.2 Driver information
Driver type
The pump is designed primarily for direct drive through a exible shaft coupling.
Under certain conditions other types of drive can be permitted, e.g. gear or pulley drives,which create radial loads onto the shaft end. Permissible radial force varies with pressure,speed and inlet conditions.For radial load requirements, contact IMO AB.
Speed
The maximum speed is 3600 rpm. Max. operating speed may be reduced depending on inletconditions. Contact IMO or use the pump selection software WinPump to nd a correspond-ing speed limit in order to avoid cavitation problems.
Rotation
The pump is designed to operate in one rotational direction only, as standard clockwisewhen 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 beoperated in reverse direction, provided the back pressure is limited to 3 bar.
