In the oil and gas industry, oil tank battery circulation is necessary for properly separating oil, gas, and water. Choosing the right pump for this application is essential for efficient and cost-effective operation. In this article, we will explore the differences between gear pumps and rotary lobe pumps in oil tank battery circulation applications.
Gear Pumps in Oil Tank Battery Circulation Applications
Gear pumps are commonly used in oil tank battery circulation applications due to their ability to handle viscous fluids. However, they have several drawbacks that can impact their effectiveness and longevity.
Overview of Gear Pumps
Gear pumps are positive displacement pumps that use two meshing gears to move fluid. As the gears rotate, they create a vacuum that draws fluid into the pump, and then the liquid is discharged through the outlet.
Problems with Gear Pumps in Oil Tank Battery Circulation Applications
Short Lifespan: Gear pumps have a relatively short lifespan of 3-6 months due to their high wear and tear. This can lead to frequent maintenance and replacement costs, which can be expensive and time-consuming.
Inefficient Operation: Gear pumps are prone to inefficiency due to wear and tear, which can impact their ability to effectively handle high volumes of fluid.
Damage from Abrasives in Crude Oil: Gear pumps can suffer from damage caused by abrasives in crude oil, which can cause further wear and tear and reduce lifespan.
Rotary Lobe Pumps in Oil Tank Battery Circulation Applications
Rotary lobe pumps are becoming more popular in oil tank battery circulation due to their improved efficiency and longer lifespan.
Overview of Rotary Lobe Pumps
Rotary lobe pumps are positive displacement pumps that use two or more lobes to move fluid. As the lobes rotate, they create a vacuum that draws fluid into the pump, and then the liquid is discharged through the outlet.
Advantages of Rotary Lobe Pumps in Oil Tank Battery Circulation Applications
Longer Lifespan: Rotary lobe pumps have a longer lifespan than gear pumps, typically lasting up to 2 years. This reduces maintenance and replacement costs and improves overall efficiency.
More Efficient Operation: Rotary lobe pumps are more efficient than gear pumps due to their improved design and ability to effectively handle high volumes of fluid.
Able to Handle Abrasives in Crude Oil: Rotary lobe pumps are better equipped to handle abrasives in crude oil, reducing the likelihood of damage and wear and tear.
FAQs
Q: What is the main difference between gear pumps and rotary lobe pumps?
A: The main difference between gear pumps and rotary lobe pumps is their design. Gear pumps use two meshing gears to move fluid, while rotary lobe pumps use two or more lobes to move fluid.
Q: Can gear pumps handle abrasive fluids?
A: While gear pumps can handle some abrasive fluids, they are more prone to damage and wear and tear from abrasives in crude oil.
Q: What is the lifespan of rotary lobe pumps in Oil Tank Battery circulation applications?
A: Rotary lobe pumps have a longer lifespan than gear pumps, typically lasting up to 2 years in oil tank battery circulation applications.
Q: How can I choose the pump for my oil tank battery circulation application?
A: When choosing a pump for oil tank battery circulation, it’s essential to consider the fluid being pumped, flow rate, pressure requirements, and other factors. Consulting with a pump expert can help you make the right decision for your application.
Conclusion
Choosing the right pump for oil tank battery circulation applications is critical for efficient and cost-effective operation. Gear pumps are commonly used but have several drawbacks, including short lifespan and inefficiency. In contrast, rotary lobe pumps offer a longer lifespan, more efficient operation, and the ability to handle abrasive fluids. By understanding the differences between these two types of pumps, you can decide which pump is suitable for your application.
