Understanding Fuel Transfer Pump Flow Rates

Do We Have A Flow Problem?

As a Bottom Loading Arm Manufacturer, we share the problem of fuel delivery flow.

To first determine if your pump really has a flow speed issue, you need to understand the way the transfer pump leak evaluation is calculated. All transfer pumps are rated at the open discharge outlet without a hose, meter, filter or nozzle connected. The rating is typically in Gallons per Minute from the USA (GPM) and also Liters per Minute (LPM) in regions where the metric system is largely used. The addition of the hose and nozzle along with any other accessories such as a fuel filter, meter or automatic nozzle will reduce the final flow speed dispensing out of your nozzle.

Tips to Increase Transfer Pump Flow Rate

Even though the addition of a filter system will affect the flow speed, the advantage usually outweighs the loss of circulation by prolonging the life of the pump. Clogged or elderly filters are among the most frequent causes of low flow levels in fuel transfer pumps. In case you've got a filter program on the gas transfer pump, it is recommended to change the filter at least once per year. (see how to Choose the correct filter here) It's best to use the shortest period of hose feasible for an application. When pumping via a 3/4 in. ID hose along with a longer period is desired, 1 way to improve flow loss is to change to a 1 in. ID hose and nozzle. Increasing the interior diameter of the hose can boost friction loss by up to 40%.
