How to Repair Deep Well Pumps
A deep well jet pump assist in moving the water that is contained in wells far below the ground. These jet pumps combine injector systems and centrifugal pump components in order to do so. The centrifugal impeller of the pump as well as the seal rest on the shaft of the motor.
What You'll Need:
- Wrench
- Replacement seal
- Replacement impeller
- Before you begin you’ll need to disconnect the PVC pipes that are connected to the deep well jet pump. Loosen each of the bolts that are around the large middle housing of the pump. Pull at the housing of the pump until it detaches. Place everything aside except for the motor section and shaft.
- Halt the motor shaft's rotation; you can do so by locking a wrench onto the shaft. Place the wrench on the section of the shaft that is behind the pump impeller. Move the impeller to the left across the threads until it is removed from the shaft.
- Pull the metal and ceramic seal from out the back of the impeller. If any part of the seal remains on the shaft once the impeller has been removed, move it across the shaft and then take it off. Connect a new metal and ceramic seal to the shaft and move it to the back of the shaft. You’ll need to replace the seal that assist with keeping water out of the motor and fixes and other problems that are a result of a damaged seal.
- Inspect the edges of the impeller for any cracks. Install a new impeller onto the shaft if there are any cracks or any other signs of damage exist on the old impeller. If there aren’t any, spray the old impellers with a water hose. This will remove any debris that are stuck on it.
- Secure a wrench onto the shaft near the seal. Move the impeller in a clockwise direction on the shaft while keeping the shaft from shifting with the wrench. Connect the two pieces of the pump housing and use a bolt to secure them together. Attach the deep well jet pump back up onto the PVC plumbing.
