What is pump priming? Priming simply means preparing or getting something ready for operation. For a centrifugal pump to work properly, you need to fill it up with water. When everything is right, a standard (non-self-priming) centrifugal pump looks like this. The pump will resume operation once the air is removed.
What Does It Mean to Prime a Pump?
Pump priming is the process of adding water to a pump in order to get it started. The water creates a seal between the pump and the water source, and also provides the initial force needed to start the pump.
Pump priming is often necessary when a pump has been turned off for a period of time, such as when a swimming pool is closed for the winter.
Without water in the pump, the seals can dry out and the pump may not be able to start. Pump priming is also sometimes used to refer to the act of stimulating the economy through government spending.
This type of pump priming is often used during times of recession or economic downturn. The government may invest in infrastructure or other projects in order to create jobs and spur economic activity.
