PRES-VAC ENGINEERING APS
Single stage Cargo pump
• Separation of lubrication oil and cargo
– Protection of cargo from leakage
– Eliminates purge operation
– Low wear cost
-
PRES-VAC ENGINEERING APS
Single stage Cargo pump
• Magnetic drive
– No mechanical seal
– Reduced Maintenance cost
– Enable quick exchange of pump unit
– Large temperature operating range
-
PRES-VAC ENGINEERING APS
• Cargo lubricated bearings
– Top and bottom bearing
– High pressure cargo from discharge pipe
– Cargo is filtered before it is used as lubrication
Single stage Cargo pump
-
PRES-VAC ENGINEERING APS
• Bottom valve
– Self closing
– Prevents return flow at the end of discharging
• Side valve
– Ensure minimum residue in pump well
– Less than 5 liter (below IMO requirements)
