How does a framo pump work?
The Framo cargo pump is a vertical single-stage centrifugal pump powered by a hydraulic motor for safe and efficient operation. The cargo pump has a built-in hydraulic motor connected to the impeller by a short independent shaft. Motor, shaft and bearings are lubricated and cooled by the hydraulic driving oil.
Why vacuum drain is there in Framo pump?
The vacuum drain line is equipped with a nozzle. The nozzle mixes the remaining liquid in the drain line with the internal tank atmosphere. This will reduce the weight of the liquid column. Consequently, the remaining liquid column can be emptied by means of a “vacuum” system on deck.
What is high capacity mode in a framo hydraulic system?
When starting the first main power pack, two feed pumps will automatically start before the power pack is started. This is called high capacity mode of feed system. This is to keep the feed pressure on the suction side of the main hydraulic pump.
What is the requirement of a cargo pump designed for a Framo system?
High or low temperature, volatile and dangerous cargoes The Framo cargo pump is designed for any cargo temperatures prevailing in tankers. The pump is continuously temperature controlled by the circulating hydraulic drive oil. The Framo cargo seal arrangement is exposed to static cargo tank pressure only.
When tank cleaning is done run the Framo pump at?
6.2 Before tank cleaning is finished, close pump s cargo discharge valve and open stripping valve to allow an increase in water level. Run the pump at approximately 110 bar against closed cargo pump discharge valve for 1-2 minutes to clean the cargo pump.
What is the requirement of a cargo pump designed for a framo system?
At what temperature of sea water the inert gas quality is good?
Low pressure seawater supply (approx. 1.5 bar) to deck seal leads to alarm and shutdown of blower. High inert gas temperature (approx. 70 deg C) leads to alarm and shutdown of blower.
How does the Framo submerged ballast pump work?
The Framo submerged ballast pump is a centrifugal pump, designed for installation inside the ballast tanks. The pump unit is mounted inside the air separator and protected by a cofferdam. A fail-safe design ensures that impeller will always be immersed in water. This is a compact design which saves space and makes the installation easy.
What is the Framo hydraulic cargo pumping system on ships?
Framo Hydraulic Cargo Pumping System on Ships. The framo hydraulic cargo pumping system is designed for a flexible and safe cargo and tank cleaning operation on ships. It consists of one hydraulic motor driven cargo pump installed in each cargo tank, ballast pumps, tank cleaning pumps, portable pumps and other consumers,…
What sizes does the Framo reversible propeller pump come in?
The Framo reversible propeller pump is supplied in three sizes, DN250, DN300 and DN400, with capacities ranging from approx. 200 m3/h to 2.200m3/h The pump is cathodic protected by a zinc-anode. A B C D E 250 300 400 See pump spec. 157 188 169 415 469 586 215 240 300 550 700 800 A B C D E
How does the Framo pump prevent oil leakage?
As you might have guessed, there is something in the Framo pump to prevent that. There is hydraulic seal that prevents hydraulic oil leakage to the cargo side. And there is cargo seal that prevents cargo leaking into the hydraulic side. But seals can leak overtime, right? so if any of these seals are leaking, how would we know?
