Impeller back clearance refers to the space or gap between the back of an impeller and the casing or shroud within a pump or turbine. This clearance is crucial as it can impact the efficiency, performance, and operational stability of the machine. Adequate back clearance helps to prevent recirculation of fluid, reduces wear, and minimizes energy losses, while insufficient clearance can lead to increased friction and potential damage. Proper design and maintenance of this clearance are essential for optimal functioning of the equipment.

How do you check impeller back clearance?
By the use of feeler gauge and with dial indicator as possible.
What is clearance between wear ring and impeller?
The clearance between the wear ring and impeller in a centrifugal pump is typically very small, usually in the range of 0.002 to 0.012 inches. It is important to maintain this clearance to ensure optimal pump performance and efficiency, as excessive clearance can lead to decreased efficiency and potential damage to the pump components. Regular monitoring and adjustment of the clearance may be necessary to ensure proper pump operation.
Yamaha wr correct way to remove water pump impeller?
Remove the side case and the water pump. Remove the right side case, and remove the impeller and shaft. Holding the back side of the impeller shaft with a wrench on the flat spots, you can now twist the impeller off.
What is churning in pumps?
When a pump is running with its discharge valve closed. The temperature inside pump rises continuously as the same liquid is continuously rotating inside pump. Due to rise in temperature of liquid, metal component's temperature also begin to rise. As the mass of impeller is much less than the pump casing. The expansion due to heat on impeller is higher than the casing. As there is very less clearance between pump casing and impeller. A time comes when impeller starts rubbing against the casing which further increases its temperature and the impeller seizes with casing. This is known as churning.
How do you fix a leaking shaft seal on your Hayward SP-1515 power-flo pump?
Replace the seal assembly. Your local pool store should have them in stock. you'll have to remove the strainer basket to get to the impeller. The impeller will then have to be removed. the seal is under the impeller. Remove the impeller by taking the back cover off of your motor. Inside you'll see all the electrics of the motor. In the center, on the shaft, it is slotted to accept a 7/16" wrench. Place a wrench on the shaft and twist off the impeller. Replace the seal assembly and put back together.
