The engine output shaft drives the torque converter's impeller , which uses fins to pump fluid - in this case engine oil - to drive vanes on the torque converter's turbine.
As the debris passes through the impeller that would normally be providing air flow to push leaves, it is shredded to many times its original size before entering the vacuum bag.
Centrifugal pumps are not positive-displacement pumps because the impeller can slip in the liquid.
Rotation of the impeller draws liquid through the inlet cap opening and pushes the liquid through the pump flow path.
Wear opens up the seal area allowing some of the higher pressure water exiting the impeller to flow back into the lower pressure area below the impeller .
The flow of water past the transducer it contained would drive a small impeller to give an electrical signal proportional to the speed of the boat.
The stator has one more blade than the impeller , and is designed to reroute the airflow from the fan in a more coherent way, as well as minimize fan noise.
Clear any broken pieces of the old impeller that could clog water flow.
This type of humidifier has a rapidly rotating fan called an impeller , which turns water droplets into a fine mist.
Offering four different models, these handheld digital instruments quickly and easily read wind speed via a sturdy impeller .
