OptiLine Product Description Flow volume: 8 - 175 l/min Max differential pressure: 16 bar Applications: Circulation and transfer

1. Applications 1.1 Functionality The ACE OptiLine pump is used for a number of different fluids: Fuel oil, vegetable oil, hydraulic oil and other hydraulic fluids, polymers, emulsions and any non-aggressive fluid with sufficient lubricating properties. If requested, the ACE pump may be certified according to any of following classification societies: 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 machines - Circulation for cooling and filtration in large...

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 Service, Maintenance and Installaton for ACE OptiLine generation 4). The maximum pressure accumulation varies with pump size, speed...

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. 3.5 Magnetic shaft coupling_ < Torque values (greater than, at least) [Nm] OptiLine pumps: For higher viscosity, contact IMO AB. OptiLine pumps:

The pump is fitted with an internal ball bearing which continously is being greased by the handling media. Model Material pump Material rotor Material idler Material seal Material Elastomers ACE Nodular cast Steel, surface Cast iron, sur- - Viton iron treated face treated During cold start-up conditions, high viscosity could cause the rated torque for the coupling to The IMO OptiLine pump series have a way to warm up the pump by leading steam into small channels at the front cover. This is recommended if cold upstart can be assumed. See Pump Unit Dimensions for dimensions of the connections...

5. Performance Typical performance values at 5 bar Flow calculated at 26 cSt, power at 260 cSt.
