Do you know which pumps in your facility require priming? Which are self-priming? If you don"t, starting a pump means you"re taking a pretty big chance. Don"t be the one that guesses wrong. Read on to find out why priming is important and which pumps will require it before getting started.
Priming the pump readies it for use. A pump"s casing must be filled with fluid before starting. If not, the pump will be unable to function. If vapor or gas exist inside the casing, the pump will become gas bound, and won"t pump. Priming is the action of filling the casing with fluid before startup.
Priming is an important aspect in maintaining the functionality of a centrifugal pump. Water or the fluid pumped acts as a coolant, preventing the pump from overheating.Failing to do so causes the pump to run dry, causing mechanical seal failure, and serious damage to pump components.
Depending upon the piping configuration, a pump may not need manual priming. A flooded suction condition is when the suction port on the pump is lower than the liquid level pumped. In this configuration, the pump is already filled with fluid andis consideredprimed.
When the liquid level is below the suction port, priming becomes more difficult. This is where having a pump with suction lift capability is important. Pumps such as the Gorman-Rupp T-Series are well known for this. Check out this video from Gorman-Rupp that explains how self-priming pumps prime.
For instance, air operated diaphragm pumps self-prime by creating a pressure differential in the diaphragm chamber. This draws in air and pulls the fluid into the suction port.
In short, to avoid failures, centrifugal pumps must always be primed before operating. Positive displacement pumps are self-priming with suction lift capability, but always check the operation manual or confer with an engineer to ensure the pump will properly function at start up without priming first.
Self-priming centrifugal pumps are unique. As the name suggests, they have the ability to prime themselves under suction lift conditions. They draw fluid up from tanks or pits below, making them easier and safer to work on than those that work below ground. Under the right conditions, they’ll free themselves of entrained gas and function normally on their own, but sometimes, they can’t.
A BRIEF NOTE OF CAUTION:Just because self-priming pumps able to pull fluid into them, doesn’t mean that they should start up dry. Self-priming, centrifugal pumps need fluid in the casing to get started. Running dry, even for a short while, will cause damage to the mechanical seal, and pump failure.
Once the pump is turned on, the impeller begins to turn in a counter clockwise rotation. The fluid inside, or the “initial prime”, flows through the volute into the discharge cavity. Here, the air and fluid separate, the air evacuates through an open ended line, or air release line, while the fluid returns to the impeller through a recirculation port.
As fluid moves up the suction line, the air ahead of the fluid is pushed into the casing and handled as the initial prime was handled through the recirculation process. Once the fluid arrives in the pump, it operates as normal.
As fluid recirculates in the pump and forces air out of the discharge chamber, it’s trying to create an area of low pressure. However, if there’s a leak in the suction line, air continues to be drawn into the pump, never allowing it to release enough to create that area of low pressure.
If a valve on the air release line is closed, and the valve on the discharge line is closed, again, it"s giving no place for the air to go and get out of the pump.
If there is excessive clearance between the impeller and the wear plate, the pump has a difficult time creating a low-pressure area. This is typically caused by wear, but could also be due to improper reassembly.
During the priming process, as discussed above, fluid is recirculated through the volute casing. If the recirculation port becomes plugged, the eye of the impeller is unable to create an area of low pressure in which to pull liquid up the suction line.
If you’ve undersized the pump for the suction line, it will not be able to create the low-pressure area it needs to prime. It’s important to understand the suction lift requirements before selecting a pump for the application. Use Gorman-Rupp’s Pump Selection Guide for the calculations you’ll need.
The ability for self-priming pumps to prime hinges on all the right conditions. The pump must be able to evacuate air from inside the pump, create a low-pressure area at the eye of the impeller, and also be properly sized for the right NPSHconditions.

Also known as gear pumps, these produce a smooth flow of liquid for applications such as cooling engines, powering hydraulic equipment, and extracting liquid from holding tanks. Pumps are self-priming after you fill the pump chamber with liquid. As liquid in the chamber is expelled, a suction force is created which allows the pump to draw liquid upward. Do not use with solids.
Pumps with an open dripproof (ODP) motor are for use in clean, dry, and well-ventilated environments. They have a relief valve to prevent pressure buildup.
Note: Pumps must be filled with liquid before use. They need a constant flow of liquid and cannot run dry. If flow control is needed, place valves or reducers on the discharge side; never restrict the inlet of a pump with a valve or reducer.
Mount these pumps in any position, even upside down. Pumps have a subfractional horsepower motor rated for intermittent use (return to room temperature before restarting). Also known as diaphragm pumps, they are for use in low-flow spraying, draining, and washdown applications. They are self-priming, which means they create a suction force to draw liquid upward. Pumps can run dry and do not require an initial fill, so they’re a good choice for applications without a constant flow of liquid. Do not use with solids.

Commonly called piston pumps, these are often used in high-pressure applications, such as hydrostatic testing of pipelines, tanks, and valves. Flow and outlet liquid pressure can be controlled by varying the air pressure. To calculate discharge liquid pressure, multiply the air pressure by the ratio shown in the table. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber.
This pump has a totally enclosed nonventilated (TENV) motor that is cooled by the liquid being pumped. Also known as a flexible impeller pump, it creates a suction force that can draw liquid upward to fill the pump chamber when your liquid source is below the pump. Mount up to 6 feet above your liquid source. Pump can pass solids up to 1/4" in diameter without clogging, so there’s no need to filter sediment and debris.
