Pumps are an essential part of many industrial applications such as water supply and waste management. The ability of a pump to generate pressure is an important factor in choosing the right one for the job. In this blog post, we will explore the different types of pumps, how they generate pressure, and compare their pressure outputs. We will also examine the advantages of both centrifugal and positive displacement pumps and their applications in different industries. Finally, we will provide a summary of their benefits and our final recommendation.
Understanding Pressure Output
To answer this question, it is important to understand the concept of pressure output and how it is measured.
Explaining Pressure Output
When looking for a pump to generate more pressure, it’s important to understand the concept of pressure output. Pressure output is the amount of pressure a pump can generate when it is operating at its maximum pressure capability. The pressure output is determined by the pump’s operating characteristics, such as the type of pump, the speed of the pump, and the pressure capacity.
The type of pump is a major factor in determining pressure output. For example, centrifugal pumps are usually better suited for generating higher pressures than reciprocating pumps. Centrifugal pumps create pressure by spinning a rotor inside the pump casing, while reciprocating pumps use pistons to move liquid through the pump.
The speed of the pump is also a major factor in determining pressure output. The faster a pump is running, the more pressure it can generate. This is because faster pumps can move more liquid in a shorter amount of time.
Finally, the pressure capacity of a pump is also an important factor in determining pressure output. Pressure capacity is the maximum amount of pressure a pump can generate before it starts to lose efficiency. The higher the pressure capacity of a pump, the higher the pressure output it can generate.
By understanding the concept of pressure output, you can determine which pump is better suited for your needs. If you need higher pressure output, it’s important to select a pump with a higher pressure capacity and a faster speed. On the other hand, if you need lower pressure output, you can select a pump with a lower pressure capacity and a slower speed.
Measuring Pressure Output
When it comes to choosing a pump, one of the most important considerations is the pressure output. Measuring the pressure output of a pump is a crucial step in determining which pump will be the most suitable for a particular application.
The pressure output of a pump is typically measured in terms of pounds per square inch (PSI). It is important to note that the pressure output of a pump is not static and can vary depending on a variety of factors including the size of the pump, the type of pump, and the type of liquid being pumped.
To accurately measure the pressure output of a pump, it is necessary to have a pressure gauge that can accurately measure the pressure. This pressure gauge should be calibrated and certified to ensure accuracy. It is also important to ensure that the pressure gauge is capable of measuring the pressure output of the pump at the required pressure.
Once the pressure gauge is properly calibrated and certified, it is then necessary to connect it to the pump and measure the pressure output. This will give you an accurate representation of the pressure output of the pump. After measuring the pressure output, you can then compare it to the pressure output of other pumps and determine which pump can generate more pressure.
By understanding and measuring the pressure output of a pump, you can make an informed decision about which pump will be the most suitable for your application. With the right knowledge and tools, you can ensure that you choose the right pump for your specific needs.

In contrast, centrifugal pumps rely on the centrifugal force of the rotating impeller to generate the pressure needed to move the liquid.
The pressure output of positive displacement pumps will depend on the type of pump being used. For example, gear pumps and vane pumps rely on the mechanical action of gears or vanes to move the liquid, and this movement creates pressure. Piston pumps use a piston to generate the pressure and diaphragm pumps rely on the movement of a flexible diaphragm to generate pressure.
When it comes to selecting the best pump for a particular application, it’s important to consider the pressure output of the pump. Positive displacement pumps are typically able to generate higher pressures than centrifugal pumps, but the specific pump type should be chosen based on the application requirements.

Advantages of Positive Displacement Pumps
Positive displacement pumps are a great choice for applications where a high pressure output is desired due to their superior ability to generate more pressure than standard centrifugal pumps. Let’s explore the advantages of positive displacement pumps in further detail.
More Pressure Output
When it comes to generating more pressure output, positive displacement pumps offer a number of distinct advantages. Unlike centrifugal pumps, positive displacement pumps can typically generate higher pressures due to their ability to move a constant volume of liquid at a constant rate. This means that for a given flow rate, the pressure generated by a positive displacement pump will be higher than that of a centrifugal pump.
Furthermore, positive displacement pumps can also be designed to produce a wide range of pressures, allowing them to meet the needs of most applications. Additionally, they are also capable of maintaining a steady flow rate, even when the system pressure is changing, making them an ideal choice for applications that require precise control over pressure.
Able to Handle High Viscosity Liquids
Positive displacement pumps are known for their ability to generate higher pressure than other pumps. This makes them ideal for handling high viscosity liquids. The reason for this is that positive displacement pumps are able to move high viscosity liquids more efficiently than other pumps.
This is due to the fact that they create a vacuum that helps to draw the liquid in from the inlet. The pressure then builds up as the liquid is forced through the pump and out the outlet. This results in higher pressure compared to other types of pumps, making them ideal for handling high viscosity liquids.
Constant Flow Rate
One of the major advantages of positive displacement pumps is their ability to provide a constant flow rate. This means that no matter what the pressure or load on the system, the pump can maintain a steady flow rate. This is due to the fact that the pump is able to create a vacuum which forces the liquid through the system.
This can be beneficial in applications that require a consistent flow rate, such as those in chemical processing and industrial cleaning. By having a constant flow rate, the system can be better regulated, allowing for more precise control over the process. Additionally, this can help reduce waste and increase the efficiency of the system.
Low Noise Output
Positive Displacement pumps are known for delivering high pressure output with minimal noise production. This is because in contrast to other types of pumps, such as centrifugal pumps, Positive Displacement pumps use pressure to move fluid from one side of the pump to the other. This means that the pump does not need to spin as fast or create as much turbulence, resulting in lower noise levels.
Additionally, Positive Displacement pumps are designed with sound-dampening components, such as rubber gaskets and sound-absorbing materials, which help to further reduce noise levels. As a result, when compared to other types of pumps, Positive Displacement pumps are typically much quieter and provide a more pleasant working environment.
Durability
When it comes to pumps, durability is a critical factor to consider. Positive displacement pumps have the edge in this area, as their construction and operation make them particularly resistant to wear and tear. These pumps consist of a few simple, durable parts that are designed to last for a long time.
Additionally, the moving parts are lubricated by the liquid being pumped, which further helps to extend the life of the pump. The result is a pump that can reliably withstand a wide range of temperatures, pressures, and operating conditions, increasing its longevity and reducing the cost of ownership.
