Glycol Pump Sizing: An Easy-to-Use Tool for Your Gas Dehydration System

The Kimray Glycol Pump Sizing Tool enables you to size and select the right pump for your dehydration system. It works for both electric pumps and energy exchange pumps.

Step 1: Enter Your Conditions

Enter your glycol pump sizing conditions

  • Start by entering your conditions.
  • Notice the glycol-to-water content and the allowable water content are filled in for you, but those can still be edited.
  • The glycol-to-water content is how many gallons of glycol it takes to remove one pound of water.
  • The allowable water content is an agreement between the buyer and the seller regarding how much water is allowed to be in the gas.
  • Click the calculate circulation rate button.
  • This will be the glycol circulation rate required to maintain these settings, so we’ll need to pick a pump that can maintain that circulation rate.
  • Notice you can also enter up to three more conditions and then the product selector will select a pump that will meet all of those conditions.
  • If you use multiple conditions, check these boxes to add them in your product search.

Step 2: Find Available Glycol Pumps

Find available glycol pumps

  • Next, scroll down to find the available pumps.
  • You can enter a maximum pressure here, or if you leave it blank, it will use the highest gas pressure in any of your conditions above.
  • Click “find available products,” and you’ll see we have several options in energy exchange pumps and electric pumps.
  • The program is confirming that the calculated circulation rate falls between the minimum and maximum glycol flow rate of the pump.
  • It’s also checking that the maximum working pressure of that pump is higher than the required working pressure entered above.
  • When we filter the products, for example if you’re looking for an electric glycol pump, you’ll notice that all of these results have the same specs.
  • That’s because this is the same pump, but these products include a motor.

Step 3: Review the Glycol Pump

Review the glycol pump

  • Once we drill into a product page in the video, we see the GEA pump by itself, and the GEA with different sized motors.
  • To see the details on each of these, you can click on the part number. This will take you to the details page.
  • Let’s say instead that you’re looking for an energy exchange glycol pump.
  • Essentially, it’s only two different pumps: the GAH and the GAJ. The differences are in the available elastomers.
  • Our standard pumps include HSN. Other options include Viton and Aflas.
  • If you’re deciding between the GAH which has a flow rate of 210 gph, or the GAJ with 450 gph, there’s a chart to help.
  • Scroll up and click here on the glycol circulation rate based on pump speed chart.
  • Shown here is the 210 and the 450 pump.
  • Our calculated circulation rate was 177.
  • If we were to pick the 210 pump, 177 would fall somewhere in here – approximately 27 strokes per minute.
  • If we were to choose the 450 pump, it would fall somewhere between here – approximately 11 strokes per minute.
  • You’d want to choose the 210 to operate at the higher end as opposed to the lower end for fear of stalling out with the 450 pump.
  • When we scroll back down to our results, we can click on the pump that we selected and once again see the details page for that product.
