How do you change a shaft seal on a pump?
Quote from the video:
Quote from Youtube video: If you can't get it off by hand you can use a strap wrench like this. And you just wrap the rubber around there and then you're able to turn it to get more tension on it.
What is a pump shaft seal?
The shaft seal is a sealing element which seals the rotating shaft, of a centrifugal pump where it passes through the non-rotating pump casing reducing fluidleakage to atmosphere or the entry of air from outside to a certain level, and keeps wear of the sealing faces as low as possible.
Which is used to prevent water leakage through the water pump shaft?
A mechanical seal is a device that is used to control leakage between a rotating shaft and a liquid- or gas-filled vessel.
What is the most common cause of pump leaks?
Wear and tear is the greatest contributor to leakage in a hydraulic system. Hydraulic fluid tends to be quite abrasive, even more so when tiny metal particles become suspended. Under high operating pressures, these wear away at components from the inside, especially pump seals where leaks most often occur.
Why do shaft seals leak?
If there are no fluids available to lubricate, the seal runs dry which causes extra friction and heat. The seal will burn or melt and become damaged, which causes fluid leakage due to the pressure. Even a few seconds of dry running can cause heat cracks or blisters, which leads to a leaking pump shaft seal.
