An air operated diaphragm pump is used instead of a centrifugal pump because it can pump liquids with particles and gases, costs less, is easier to control, and is quieter.
The choice between an air operated diaphragm pump and a centrifugal pump is a common decision for many industrial applications. When it comes to selecting the best pump for the job, it is important to understand the advantages and disadvantages of each type of pump. Air operated diaphragm pumps are able to handle highly viscous fluids and particulate contamination, while centrifugal pumps have limited ability in these areas. This article will provide an overview of the advantages and disadvantages of each type of pump, a comparison of the two, and why air operated diaphragm pumps are the preferred choice.
Advantages of Air Operated Diaphragm Pump
Air operated diaphragm pumps offer a number of advantages over centrifugal pumps, including their ability to handle viscous fluids, highly contaminated fluids, and their low maintenance and high reliability.
Ability to Handle Viscous Fluids
One of the major advantages of an air operated diaphragm pump over a centrifugal pump is its ability to handle viscous fluids. This makes it a great solution when pumping high viscosity fluids such as lubricants, glues, resins and adhesives. The flexibility of the diaphragm allows it to easily pump these types of fluids, as it can move through them and avoid any clogs or blockages.
On the other hand, centrifugal pumps struggle to pump viscous fluids due to the fact that they rely on centrifugal force to move the fluid. This makes it difficult to move the fluid through the pump, resulting in clogs and blockages. With air operated diaphragm pumps, these issues can be avoided, making them a great choice for pumping viscous fluids.
Ability to Handle Highly Contaminated Fluids
When it comes to handling highly contaminated fluids, an air operated diaphragm pump is the ideal choice over a centrifugal pump. The key advantage of an air operated diaphragm pump is its ability to handle fluids of varying viscosity and solids concentration. This makes them an ideal choice for applications that require the handling of highly contaminated fluids, as the pump is able to separate out the particles and pump them out of the fluid with ease.
Furthermore, air operated diaphragm pumps are also designed to be able to handle a wide range of flow rates and pressure ranges, making them highly versatile and reliable in industrial applications. Finally, they are also relatively low-maintenance, requiring less upkeep when compared to centrifugal pumps. This makes them a great choice when you need a reliable and efficient pump to handle highly contaminated fluids.
Low Maintenance and High Reliability
One of the major advantages of air operated diaphragm pumps over centrifugal pumps is their low maintenance and high reliability. Diaphragm pumps require little maintenance and are extremely durable, making them a great choice for long-term operations. Their internal components are designed to last for years and are unlikely to need any repairs or replacements.
Furthermore, the air operated design of the pumps means that there are fewer moving parts, reducing the risk of wear and tear. In addition, the pumps are able to handle a wide range of liquids, from hazardous chemicals to water, making them suitable for a variety of applications. As a result, diaphragm pumps can offer an unbeatable combination of low maintenance and high reliability.
Disadvantages of Centrifugal Pump
While centrifugal pumps have a wide range of applications, they have some significant disadvantages that may make an air operated diaphragm pump the more appropriate choice.
Limited Ability to Handle Viscous Fluids
Centrifugal pumps are widely used in a variety of applications due to their low cost, easy maintenance and generally low energy requirements. However, one of their major disadvantages is their limited ability to handle viscous fluids. Viscous fluids are thicker and more difficult to move than non-viscous fluids, and centrifugal pumps can struggle to achieve the necessary pressure to move them. This can lead to poor performance and operational issues.
An air operated diaphragm pump is a great alternative for viscous fluids. This type of pump uses air to force a diaphragm to move up and down, creating a pumping action and allowing viscous fluids to be moved with greater ease. They are more efficient than centrifugal pumps and can handle higher pressures, making them ideal for applications that require the movement of viscous fluids.
Limited Ability to Handle Particulate Contamination
When compared to an air operated diaphragm pump, centrifugal pumps have a limited ability to handle particulate contamination. This is primarily because centrifugal pumps rely on the centrifugal force to move fluids through an impeller. Particulate contamination can become lodged in the impeller and cause clogging or blockages, resulting in decreased performance.
Air operated diaphragm pumps, on the other hand, use compressed air to drive a flexible diaphragm, which can easily pass through particulate contamination without issue. Therefore, when dealing with particulates, an air operated diaphragm pump is often the better choice.
Comparison of Air Operated Diaphragm Pump and Centrifugal Pump
In order to better compare the two types of pumps, it is important to consider the following factors: cost, installation and operational requirements, maintenance requirements, safety considerations and common applications.
Cost Considerations
When it comes to cost considerations, there are several factors that should be taken into account when choosing between an air operated diaphragm pump and a centrifugal pump. An air operated diaphragm pump is generally less expensive to purchase and maintain than a centrifugal pump. Additionally, since the air operated diaphragm pump does not require electricity to operate, it can be used in applications where electricity is not available, saving on the cost of electrical installation.
Furthermore, the diaphragm pump is capable of pumping a wide range of fluids, from viscous liquids to corrosive and abrasive materials, with minimal wear and tear, resulting in less frequent maintenance and longer service life. However, centrifugal pumps have their own advantages. They tend to be more efficient than air operated diaphragm pumps and can handle higher flow rates.
Additionally, they are easier to install and maintain since they do not require additional air supply. Therefore, when considering the cost of a pump, it is important to take into account the cost of purchase, installation, maintenance and the expected service life of the pump.
Installation and Operational Requirements
When deciding between an air operated diaphragm pump and a centrifugal pump, it is important to consider the installation and operational requirements of each option. An air operated diaphragm pump requires a compressed air source, which must be provided and connected to the pump in order for it to operate. Additionally, the pump must be primed prior to operation by filling it with liquid. On the other hand, a centrifugal pump does not require an external air source and does not need to be primed prior to operation.
The operational requirements of an air operated diaphragm pump are also different from those of a centrifugal pump. An air operated diaphragm pump needs to be regularly maintained in order to ensure its efficient operation, while a centrifugal pump requires minimal maintenance. Additionally, air operated diaphragm pumps tend to be more sensitive to changes in the suction pressure or suction lift, and are not suitable for applications involving high suction lifts. In contrast, centrifugal pumps are less sensitive to changes in suction pressure or suction lift, and can be used for applications with higher suction lifts.
Overall, an air operated diaphragm pump may be the more appropriate choice for applications that require a reliable, low-maintenance pump, while centrifugal pumps may be more suitable for applications involving higher suction lifts. It is important to consider all of the installation and operational requirements of each type of pump before making a decision.
Maintenance Requirements
When it comes to maintenance requirements, an air operated diaphragm pump is the clear choice over a centrifugal pump. Air operated diaphragm pumps require less frequent maintenance and are less expensive to maintain than centrifugal pumps. The diaphragm design eliminates any internal seals and bearings, which are common sources of wear and tear in centrifugal pumps. Furthermore, the diaphragm design is much less susceptible to clogging and can handle larger particles than a centrifugal pump.
In addition, air operated diaphragm pumps are much quieter than centrifugal pumps and are less likely to vibrate or shake. This makes them a better choice for sensitive environments or applications where noise or vibration could be an issue. Finally, air operated diaphragm pumps can be easily serviced and repaired on-site, making them a more convenient option for many industrial applications.
Safety Considerations
When it comes to selecting a pump for a specific application, safety should always be a priority. In comparing an air operated diaphragm pump and a centrifugal pump, there are several safety considerations to take into account.
When it comes to the air operated diaphragm pump, the most obvious safety consideration is its use of compressed air. This can present a hazard if the air pressure is too high, or if the air compressor is not properly maintained. Additionally, the diaphragm can break if it is subjected to too much pressure, which can cause a sudden release of air.
Centrifugal pumps also have their own safety considerations. These pumps can be difficult to maintain and can be a safety hazard if not monitored regularly. Additionally, if the pump is not properly sealed, it can create a vacuum that can cause the pump to draw in air and create a potential hazard.
Overall, when choosing between an air operated diaphragm pump and a centrifugal pump, it is important to consider the safety of the application and the environment in which it is being used. Both pumps have unique safety considerations, so it is important to weigh the pros and cons of each type of pump before making a decision.

Air operated diaphragm pumps are typically used for applications that require the pumping of low-viscosity fluids such as water, gasoline, and other low-viscosity substances. These pumps are also well suited for applications that require the pumping of fluids with suspended solids or other particles, as the diaphragm design helps prevent clogging. In addition, these pumps are often used for applications that require high-pressure capabilities or require the pump to be operated in hazardous environments.
On the other hand, centrifugal pumps are typically used for applications that require the pumping of high-viscosity fluids such as oil, coolant, and other thick liquids. These pumps are also well suited for applications that require the pumping of fluids with suspended solids or other particles, as the centrifugal design helps prevent clogging. In addition, these pumps are often used for applications that require high-flow capabilities or require the pump to be operated in non-hazardous environments.
In conclusion, when considering which type of pump to use for a given application, it is important to understand the common applications for both air operated diaphragm pumps and centrifugal pumps. Air operated diaphragm pumps are generally used for applications that require the pumping of low-viscosity fluids, while centrifugal pumps are generally used for applications that require the pumping of high-viscosity fluids. Furthermore, both types of pumps are well suited for applications that require the pumping of fluids with suspended solids or other particles, as their respective designs help prevent clogging.
