Description
FRAMO is a Cargo Pump model, coded ^KAAA. Typical service: support role in cargo; installed across most merchant fleet segments. Installed on oil tanker, chemical tanker, LNG carrier.
Did you know
- Framo, founded as Frank Mohn AS in 1938, introduced the high-pressure, hydraulically driven marine pump in the early 1960s, which was a significant innovation at the time. This led to the development of the concept of one fixed, installed submerged pump for each cargo tank in the 1970s, marking the beginning of Framo's main operation in total cargo handling systems for tankers.
- The FRAMO cargo pump is a core offering within Framo's marine cargo pumping solutions, alongside other specialized pumps like submerged liquefied gas pumps, ballast pumps, and portable pumping systems.
- The FRAMO cargo pump is chosen for its ability to safely and efficiently handle any liquid cargo, regardless of specific weight or viscosity, due to its vertical single-stage centrifugal design and hydraulic motor. Its submerged installation eliminates the need for a pump room, increasing cargo capacity and enhancing safety.

Engineering Knowledge
General engineering guidance only — it may contain errors. Always follow the equipment's own documentation and the judgement of a qualified engineer.
Cargo pump cofferdam cannot be purged (no air, inert gas, or liquid exits check pipe).
Check for insufficient purging medium supply by inspecting valves, hose connections, and the purging medium relief valve (which should open at approximately 3 bar). Also, check the exhaust trap and deck piping for blockages and clear them if possible.
Cargo pump cofferdam is blocked.
Disconnect the check pipe from the pump unit (lower seal house) and carefully purge to determine if the blockage is in the check pipe or the pump/pipe stack cofferdam. Use steam or solvent to dissolve the blockage, or dismantle the pump if necessary. Perform a leak test after reassembly.
Cargo leakage to pump cofferdam is observed.
Perform a leak test on the pump cofferdam system at approximately 3 bar. Check for leakage, using soapy water if needed to locate the source. If a worn cargo seal is suspected, replace the cargo seal set and inspect the ceramic sleeve for damage.
Hydraulic oil leakage to pump cofferdam is observed.
Drain the pump return side before dismantling. Disconnect the pump head/unit from the pipe stack/casing. Pressurize the pump unit return side at approximately 4 bar and check for leakage to the cofferdam side. Leak test the pump pipe stack/casing at a maximum of 7 bar on the cofferdam side and check for leakage to the return side.
Shaft seal is leaking, causing hydraulic oil to enter the cofferdam.
Replace the shaft seal. If feasible, the removed seal can be reconditioned. Evaluate if other changed parts like sleeves or mechanical seals are suitable for reconditioning.
Leaking seal element in flange connection is causing hydraulic oil to enter the cofferdam.
Check the sealing surface for any damage and repair if necessary. When reassembling, replace any damaged seal elements. Ensure bolts are tight and check for pitting corrosion in seal faces.
Crack or pinhole in piping is causing hydraulic oil to enter the cofferdam.
Contact a Framo Service Station for further assistance and repair.
Cargo leakage to cofferdam is caused by a worn cargo seal, but no leakage is detected during a leak test.
Replace the cargo seal set and carefully inspect the ceramic sleeve for any damage or wear. The upper seal lip typically seals when the cofferdam is pressurized, which may mask the worn seal during a leak test.
Cargo leakage to cofferdam is caused by a leaking seal element in a flange connection.
Check for loose bolts and pitting corrosion in the seal faces. Repair any corrosion found and replace damaged seal elements during reassembly.
Cargo leakage to cofferdam is caused by a crack or pinhole in the pump/pipe stack piping.
Contact a Framo Service Station for specialized repair and advice.
