Std Line Product Description Flow volume: 10 - 180 l/min Max differential pressure: 16 bar Applications: Circulation, lubrication and transfer

1. Applications 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, 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,...

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 instruction for low-pressure pumps). The maximum pressure accumulation varies with pump size, speed and...

3. Technical Data 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 025 032 038 Sound level dB [A] 58 58 58 3.5 Fluid viscosity Lube 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 oil For higher viscosity, contact IMO AB. Lube Line (Seal version code V): -20 – +90 °C Fuel...

The pump is fitted with an internal ball bearing which continously is being greased by the handling media.
