5/5/2023 0 Comments Transfer pump![]() The gears have meshing, which doesn’t allow any fluid to pass in between them. As the gears spin against each other, this creates an expanding volume on the inlet side – where water is brought in, trapped in the gear teeth, brought around the gears, and finally squeezed out the discharge. Gear pumps have two gears inside a tight casing. They are also more complicated and require a lot more maintenance. However, gear pumps are more expensive than centrifugal pumps. They don’t need priming, and they are also great for handling viscous liquids, like fuel oil. Gear pumps are a type of positive displacement pump. Advantages and Disadvantages of Centrifugal PumpsĪnother type of oil transfer pump commonly found in ships is gear pumps. These pumps give the highest flow rates of any type of pump. Instead, it will just circulate the air inside the pump.īut because of the way they work, centrifugal pumps can move extremely high capacities of liquid. The impeller will spin, but it won’t pull in anything. If nothing exits the discharge, there won’t be low pressure inside the pump. That’s why centrifugal pumps need priming first. ![]() This design forces the water out of the discharge instead of turning the water around inside the pump.Īs the oil leaves the discharge, this creates low pressure inside the casing, which pulls in even more liquid. The volute casing has a snail shape, where it starts small and expands towards the exit. As it spins, the vanes push water to the sides using centrifugal force – hence the name. Speaking elementarily, the impeller is essentially a spinning disk with vanes that curve outward. The two main components of a centrifugal pump are its impeller and the shape of its volute casing. Once the water exits, it creates low pressure inside the pump, which pulls in more oil. Because of this, the liquid pushes to the sides of the casing and out the discharge. Inside a centrifugal pump, an impeller spins at incredibly high speeds. Running a centrifugal pump dry can have serious consequences, including destroying the impeller inside.Ĭentrifugal pumps work in a certain way that makes dry-running damaging. However, one downside to centrifugal pumps is that they need priming first. These are the most simple, easy to maintain, and affordable types of oil transfer pumps. And the same is true when it comes to moving heavy oils. Centrifugal Oil Transfer PumpsĬentrifugal pumps are by far the most widely-used type of pump in the world. Let’s have a closer look at some of the more popular ones. All of these have their own set of advantages and disadvantages. There are several different types of oil transfer pumps you can find in ships. And if your pump is inadequate, you won’t be able to fuel your ship correctly. If something goes wrong, you will be in a very hazardous situation. That’s why having reliable oil transfer pumps is critical for the marine industry. And can be used for draining oily bilges and moving diesel oil from tank to tank. Oil transfer pumps are also responsible for moving the excess oil in the overflow tank back into the storage tank. Doing this is the primary function of the oil transfer pump. These oils initially go into the ship’s bunker tanks (found in the double bottom) from the port or bunker boat.įrom there, the oil transfer pump then carries the HFO to the settling tank inside the engine room. ![]() Most ocean vessels use HFO (heavy fuel oil) to power their engines. In the marine industry, oil transfer pumps are responsible for transferring fuel oil into and around your ship. What are Marine Oil Transfer Pumps?Īs the name suggests, oil transfer pumps carry oil and other viscous liquids. How and where to install your oil transfer pumpīy the end of it, you’ll know everything you need to know about marine oil transfer pumps.What to look for in an oil transfer pump.The different types of oil transfer pumps.In this article, we’re going to have a complete look at oil transfer pumps: That is why you cannot take any chances with your marine oil transfer pump. Oil transfer is not only essential for a vessel to reach its destination, but it is also very hazardous. One of the most critical pumps to have onboard every ship is the oil transfer pump.
