HYUNDAI SUBMERGED CARGO PUMPING SYSTEM based upon hydraulically driven submerged cargo pumps, is used for chemical and product carriers, crude carriers, FPSO units and others. The system is designed for profitable cargo handling, efficient stripping and tank cleaning. HHI-EMD uses state-of- the-art computer aided design technology and is staffed with a qualified and experienced team of engineers and technicians to design, manufacture and factory test each pump. How It Works Discharging Hi-Well Cargo Pump can be started from the remote control panel or the local control valve. Through the PFC block on the pump top plate, pump always runs at the maximum discharge flow rate without regulating of discharge valve. According to the discharge loads, the pump speed is changed by the hydraulic motor. Hydraulic power package sustains the best operating conditions irrespective of the type of cargos. Power consumption is automatically matched to the discharge situation. Stripping When the cargo tank is almost empty, stripping is started to optimal cargo empty. First, reduce the pump speed to suitable speed for stripping and close the discharge cargo valve, and then insert compressed air, inert gas or nitrogen into the pipestack to empty the cargo in pipestack. During stripping, the pump impeller acts as a non-return valve to prevent cargo from returning to tank. Hyundai submerged cargo pumps also satisfy the class regulation for stripping.
