b) Crack in pipe stack - can occur if the cargo pump is vibrating heavily for some abnormal reasons. A hydraulic oil leak is very rare under normalĬonditions, but if a hydraulic oil leak does occur, there could be three reasons: a) Hydraulic oil seal - the life time is normally very high (>10.000 running hours). If the cargo pump has a hydraulic oil leak you normally have to split the pump to identify the leak. If this is not the case and the cargo leakage is not possible to detect, you have to split the cargo pump and pressure test the main components separately. The reason could be that the 3 bars pressure in the cofferdam is pressing the upper lip (facing the cofferdam) around the pump shaft. Note: If the cargo leakage is not possible to identify and the 3 bar pressure is stabilized for a long period of time during the pressure testing, it is still possible that the cargo seal in the pump is worn out and have to be changed. Use soapy water for better detecting of the possible leakage. After approximately 5 minutes check all flanges around the cargo seal, riser pipe and all other connections for possible leakages. Connect the purging medium to the test flange and increase the pressure to 3 bars.

Dismantle the cofferdam’s riser pipe flange on the top cover plate and install a test flange with pressure gauge (see figure 1). The cofferdam can be pressure tested by blinding off the purging medium relief valve by means of a rubber gasket. So always identify where you have a leak first!

The crew on some ships start to automatically change the pump’s cargo seal as soon as there is a cargo leakage - although the leak may be somewhere else. If a cargo leakage is detected the complete cargo pump’s cofferdam has to be pressure tested to identify the leak. The best way is to pressure test the pump’s cofferdam. If the purging routine has detected a cargo leakage (more than 2 litre / day), and the evaluation indicates that action must be taken, first thing you have to do is to identify the leakage.

How to perform pressure test of FRAMO submersible Cargo Pump

#Framo pump hydraulic motor manual portable

The cargo hose for the portable pump to be tested and maintained according general in forced rules and procedures valid for cargo hoses onboard the vesselįig: Pressure test of FRAMO submersible Cargo Pump.Make a visual control of the complete unit.If excessive leakage is noted, actions must be taken.TK80: remove cofferdam plug and tilt pump to horizontal position. TK 150: remove impeller nut and raise pump head to vertical position. Check cofferdam on pump head for leakage.Drain off approximately one cup hydraulic oil from each of the extension hoses and from the concentric hose.Note! First disconnect the pressure hose, then disconnect the return hose. Disconnect the extension hoses from the hydraulic ring line.Check for hydraulic oil leakages on all connections.Operate at this speed only for a short period. Increase speed until rated discharge pressure, or to max.When water is flowing from the test hose, connect a pressure gauge. Check if the pressure gauge on the control valve is working. Start the pump slowly, and run with low speed.Note! First connect the return hose, then connect the pressure hose. Connect the extension hoses to the hydraulic ring line.Hoist the portable pump into a drum containing fresh water.Install a “Minimess” test coupling and a “Minimess” test hose (equipment in the Test kit) on the blind flange.

The pump discharge flange to be equipped with a blind flange.
