The combined effects of gravity and air pressure make it difficult for air to enter the pump or suction line if it is positioned below the level of the liquid that is going to be pushed.
This is because gravity pulls things down, while air pressure pushes things up.
If you have a storage tank buried underground, for instance, you will need to raise the pump above the level of the liquid before you can empty the tank.
During the initial phase of operation, air will be present in the suction line; in order for the pump to begin discharging liquid, this air must either be evacuated or displaced.
Because the vast majority of pumps are intended to transfer a particular liquid, it is an extremely challenging task to extract a gas from the system.
There are a few distinct routes one might take to stay away from this problem.
Utilizing an auxiliary pump is a viable option for clearing the suction line.
When the pump is switched off, fluid may leak from the suction line if it is not equipped with either a non-return valve (also known as a foot valve) or an evacuation tank.

However, in order to implement any of these solutions, new equipment, pipes, and operating procedures will need to be established.
When utilized for these aims, it is ideal to make use of a pump that, upon initial commencement, is able to first expel air from its suction side.
A self-priming pump is the name suggested for this particular category of pump.
As the pump removes air from the suction side, the air pressure causes liquid to be sucked into the suction line.
This procedure can't be completed until the head pressure of the liquid is equal to the air pressure in the surrounding area.
In the case of water, a pump that is operating at peak efficiency can self-prime to a height of around 10 meters when operating far from the source of the fluid being pumped.
However, the specific limit will change depending on the type of liquid you are using as well as other factors such as altitude and temperature.
To some extent, all pumps that use positive displacement are similar in this regard.
This includes lobe pumps, vane pumps, diaphragm pumps, and both internal and exterior rotary gear pumps specifically.
There is one specification that is shared by all positive displacement pumps, and that is the utilization of close-tolerance components to prevent fluid from leaking back into the suction line.
The effectiveness of the seals produced by these close-tolerance components is directly proportional to a positive displacement pump's capacity to expel air from its suction line.
If the pump is allowed to run dry, the seals on it will eventually wear out, and the pump will stop working.
When liquid first enters a reciprocating pump, there is a possibility that a mixture of liquid and air will occur, which raises the possibility of cavitation.
In such an atmosphere, bubbles of vapor form on the suction side of the pump and continue to grow there.
When the bubbles arrive at the high-pressure discharge side of the pump, they burst violently, causing vibration and perhaps causing damage to the pumping gear.
When the bubbles reach the low-pressure suction side of the pump, they remain intact.
Before using a positive displacement pump for an application that requires it to self-prime and be run dry for any length of time, it is essential to verify with the manufacturer whether or not these conditions are acceptable for the pump.
The communication of rotational energy from the impeller to the liquid in centrifugal pumps results in the liquid being propelled forward.
The suction and discharge ports of the pump do not have any kind of sealing.
Due to the fact that centrifugal pumps are unable to extract air from a suction line when the liquid level is below the impeller, these pumps are unable to be used for the transfer of gases.
When this occurs, the pump is referred to as being air-bound, and it is possible for its bearings to overheat since they do not receive the lubrication and cooling that they normally do from the fluid that is being pumped.

However, with a few modifications to the typical design, a centrifugal pump can be made to be self-priming.
This means that the impeller and the volute casing are effectively surrounded by a tank, which ensures that the pump is always submerged in liquid that is sufficient to prime the pump, as well as provide lubrication, cooling, and other benefits.
Self-priming pumps have a number of advantages over traditional pumps, including the following: 1.
(so long as priming time is not too long).
The reservoir of a self-priming centrifugal pump that was just recently installed needs to have the appropriate amount of liquid added to it.
The power of a pump to create a vacuum on the suction line from liquid that is already present in the pump's housing is what is meant when the phrase "self-priming" is used to describe the pump's functionality.
Even a centrifugal pump that is described as "self-priming" will be unable to perform its function if there is no liquid present.
It is possible for centrifugal pumps equipped with the appropriate bearings and seals to run dry for brief periods of time.
However, doing so for vast periods of time is not recommended.
Self-priming pumps prevent the mixing of air and liquid by taking in some air before discharging the water.
This allows the pump to prime itself.
This is done by combining air and water during the priming process, which causes the air to expand and rise while the water contracts and sinks.
This gives the appearance that the air is expanding while the water is contracting.
Gravity pulls the water, which is now completely devoid of air, downhill, where it combines with the air that is still present in the suction line inside the impeller.
This process is repeated several times in order to ensure that the suction tube is totally free of air.
As soon as this takes place, water is forced into the suction line and closer to the impeller by the pressure in the surrounding air, and pumping can then begin.
