centrifugal pumps and blowers work on the same principal then why centrifugal pumps are needed to be primed but blowers are not?

I think it's exactly as you already pointed out:JaredJames said:Care to expand on that? What is the difference aside from one is primed and one isn't? What causes one to be always primed?
Generally when people talk about pumps, they're talking about a machine that moves liquid. Similarly, when referring to blowers, they're talking about machines that move gas. Also, we would naturally assume the blower to have air in it before it starts up, hence it is already "primed", whereas a pump that has air in it is starting out with the wrong working fluid.JaredJames said:Well I assume your view is a pump deals with liquid and blower with gas.
You need to prime a pump becuase it isn't full of liquid and isn't capable of generating enough vacuum to pull the liquid into itself. A blower/fan is always full of air unless it is in space.JaredJames said:Care to expand on that? What is the difference aside from one is primed and one isn't? What causes one to be always primed?
The main difference between centrifugal pumps and blowers is the direction of gas or liquid flow. In centrifugal pumps, the flow is radial, meaning it moves away from the center of rotation. In blowers, the flow is axial, meaning it moves parallel to the axis of rotation.
Centrifugal pumps are preferred for priming pumps because they can create a lower pressure at the inlet, allowing them to draw in air and prime the pump quickly. Blowers, on the other hand, are designed for higher pressure applications and may not be able to generate enough suction to prime the pump effectively.
Yes, in some cases, blowers can be used to prime pumps. However, this is typically only done when the pump is located above the liquid level and there is no other option for priming. In this scenario, the blower creates a vacuum to draw the liquid up into the pump and prime it.
One potential advantage of using blowers for priming is that they can handle larger volumes of gas or liquid. This can be beneficial in certain applications where a large amount of priming is required. Additionally, blowers may be more energy-efficient in some cases.
Centrifugal pumps are commonly used for moving liquids, such as water, chemicals, and oil, in industrial, commercial, and residential settings. Blowers, on the other hand, are often used for aeration, ventilation, and pneumatic conveying in industries such as wastewater treatment, mining, and manufacturing.
