IMO AB Triple screw pump
Model: ACF 90N4 IRBO
Max. Differential pressure: 16 bar
The ACF pumps are used for a number of different fluids:
Lubrication oil, fuel oil, vegetable oil, hydraulic oil and other hydraulic fluids, glycols,polymers, emulsions, and any non-aggressive fluid with some lubricating properties.
Typical applications are:
• Lubrication of diesel engines, gears, gas and steam turbines, hydro turbines, paper machines. Main and prelube pump for diesel engines.
• Circulation for cooling and filtration in large machineries and hydraulic systems, pumping transformer oil for insulation in transformers.
• Transfer onboard ships, in oil factories, refineries, tank farms etc.
• Filling of pressure chambers in hydraulic presses.
