Selecting the Right Transfer Pump
Determining the best pump solution for your application requires some investigation into some of the operating parameters of the application. These five questions will help steer you in the right direction when it comes to determining what fluid management solution is right for you.
#1 - What is the maximum pumping distance?
The distance gasoline must travel is a major determining factor when choosing a pump. You need to fully understand how far you are pushing the fuel or how far you are pulling it, and any vertical lift that needs to be accounted for.
#2 - What is the desired flow rate?
The flow rate is a measure of how quickly the fuel is dispensed. The size of the pump chamber and the power source play a role in the maximum flow rate attainable. Pumps that produce higher flow are typically more expensive, so the goal is to balance flow rates with productivity while not over-sizing or under-sizing the pump.
#3 - What is your operating environment?
Certain features make a fluid transfer pump suitable for a particular environment. While some transfer pumps are manufactured to operate with hazardous fuels, you want to consider the operating environment, such as if the pump is located outdoors and exposed to extreme weather. Also, consider if you need the flexibility of a mobile pumping unit.
#4 - What is the available power source?
Most transfer pumps operate from single phase AC, 3-phase AC, and DC power sources. Each power source has its strengths and limitations, but be advised that pump head performance may vary depending on the available power and power quality. If you are operating in a remote area, you may consider engine-driven pump models, with the added benefit of throttle/pump speed control. There are also pump drive options for truck-mount applications where hydraulic systems or PTO connections can be used.
#5 - What external factors affect the application?
Every gasoline transfer pumping application has constraints and restrictions. Items such as hoses, nozzles, reels, elbows, and meters add pressure, which can potentially slow down output. By taking all of these factors into consideration, your pump will operate as expected after installation.
