What is airlock in water pumps?
An air lock is a restriction of, or complete stoppage of liquid flow caused by vapour trapped in a high point of a liquid-filled pipe system. The gas, being less dense than the liquid, rises to any high points. This phenomenon is known as vapor lock, or air lock.
What causes airlock in water pump?
The main cause of an air lock in pipes is when pockets of air are trapped by the flowing water, preventing the free flow of water. Also, cold water pipes have less pressure compared to the hot water pipes; as a result, it’s mainly hot water pipes that are affected by air locks.
When do you have entrained air in your pumping system?
It’s safe to say, if fluid is coming out, air is definitely getting in. Submersible, immersible, or pumps in suction lift applications can be prone to air entrainment when the minimum submergence level in the tank/pit are not met.
How does an air bound heating system work?
The use of a pony pump to force air out of a hot water heating system (photo) is described at AIR BOUND HEAT SYSTEM REPAIR by PUMP. On 2017-12-14 by Arthur – how can I cure bubbling gurgling noises at my heating system?
What happens when there is no air in a pump?
The amount of air that can be handled by a pump varies from pump to pump. But one thing is certain, all fluid handling pumps operate better when no air is present. If you’re experiencing issues with a pump making too much noise, or vibrating excessively, ask us about it!
Where does air come from in a pump?
LEAKY SUCTION LINE Air can easily enter pumps through leaks in the suction line at elbows, joints, etc. It’s safe to say, if fluid is coming out, air is definitely getting in.

What is the minimum flow rate for a centrifugal pump?
Typical single stage centrifugal pump. Minimum flow rates will also play a major role when managing air entrainment issues. The higher the air entrainment percentage the more flow that will be required to push or sweep the air bubbles pass the impeller eye (see Figure 1).
