MARFLEX ELECTRIC-DRIVEN DEEPWELL CARGO PUMPS

AIMS:

To provide participants with a clear, practical, and in-depth understanding of Marflex electric-driven deepwell cargo pumps, focusing on design philosophy, operation, control systems, maintenance, troubleshooting, and safe cargo handling practices on chemical and product tankers.

OBJECTIVES:

On completion of this course, participants will be able to:

• Understand the design concept and operating principle of Marflex electric deepwell pumps
• Explain why electric-drive deepwell pumps are preferred over hydraulic systems
• Identify and describe all major components: deck arrangement, pipe stack, and pump head
• Operate Marflex deepwell pumps safely under varying cargo conditions
• Apply correct speed control methods based on cargo properties
• Understand oil-lubricated shaft systems and their advantages over cargo-lubricated designs
• Monitor seal integrity, cofferdam condition, and leakage detection
• Carry out correct stripping procedures in compliance with IMO requirements
• Recognise common faults, alarms, and abnormal operating conditions
• Perform routine checks and first-line maintenance safely and effectively
• Improve cargo discharge efficiency while minimizing wear, cavitation, and residual cargo
