What is the radial clearance of an Asphalt Gear Pump?
Hey there, folks! As a supplier of Asphalt Gear Pumps, I often get asked about the radial clearance of these pumps. So, I thought I'd write a blog post to clear up any confusion and give you a better understanding of what it is and why it matters.
First off, let's talk about what an Asphalt Gear Pump is. An Asphalt Gear Pump is a type of positive displacement pump that uses two meshing gears to move asphalt or other viscous fluids. These pumps are commonly used in the asphalt industry for applications such as asphalt mixing, paving, and storage.
Now, let's get to the main question: What is the radial clearance of an Asphalt Gear Pump? The radial clearance is the space between the outer diameter of the gear and the inner diameter of the pump housing. This clearance is critical because it affects the performance and efficiency of the pump.
If the radial clearance is too large, the pump will experience excessive leakage, which can lead to a decrease in flow rate and pressure. On the other hand, if the radial clearance is too small, the gears may bind or seize, causing damage to the pump.
So, how do you determine the correct radial clearance for an Asphalt Gear Pump? Well, it depends on a few factors, including the type of asphalt being pumped, the temperature of the asphalt, and the viscosity of the asphalt. Generally speaking, the radial clearance should be between 0.002 and 0.004 inches for most asphalt applications.
It's also important to note that the radial clearance can change over time due to wear and tear on the gears and pump housing. That's why it's important to regularly inspect and maintain your Asphalt Gear Pump to ensure that the radial clearance is within the recommended range.


Now, let's talk about some of the benefits of having the correct radial clearance in your Asphalt Gear Pump. First and foremost, it ensures that the pump operates efficiently and effectively, which can save you money on energy costs and maintenance. It also helps to prevent damage to the pump, which can extend its lifespan and reduce the need for costly repairs or replacements.
In addition to having the correct radial clearance, there are a few other things you can do to ensure the optimal performance of your Asphalt Gear Pump. For example, you should always use the correct type of lubricant for the pump, and you should make sure that the pump is properly installed and aligned.
