When it comes to the design and creation of a hydraulic pump system, you might have heard the terms, ‘water pump flow rates’ and ‘water pump head pressure’ — but, what do these terms mean? In particular, what is the difference between the two?
PumpWorks explores the two in more detail in this blog, so keep reading if you would like to find out more about pump flow rate vs pressure.
Pump pressure refers to the measure of resistance to flow. This is often measured in pounds per square inch (PSI), indicating the resistance that the pump can withstand. However, to have pressure, there must be flow.
The flow rate of a pump is measured in gallons per minute (GPM) and indicates the rate of fluid that flows through the pump system. This can be determined by the speed of the pump — fixed-speed pumps will have a constant flow rate, whereas a variable speed pump will have a flow rate that either increases or decreases according to the pump’s speed setting.
As you can see, the two terms should not be used interchangeably as they are two different concepts. The relationship between them is clear: if pump pressure increases, the flow rate will likely decrease. Knowing the difference between them and how they influence each other is key to understanding how to make pump systems more efficient, boosting performance.
For instance, knowing how much a pump system can withstand in terms of resistance to flow allows you to select the appropriate pump components and motors to design and create an efficient and effective hydraulic pump system.
