Einleitung

Follow this guide to remove the sections of riser main from a Bush pump. You can either remove the entire riser main for replacement, or just remove and replace or repair a broken section.

This guide uses the help of a tripod to lift the riser main. It can, alternatively, be lifted using lifting spanners, but a tripod allows the process to be done by two people. Still use caution when using a tripod.

    • Use a pipe wrench to loosen and remove the pump spout.

    • Inspect the spout for obstructions or potential contaminants.

    • Place the spout on a clean surface to prevent any contamination.

    • Place one wrench on the top of one of the pump riser plate bolts.

    • Place another wrench around the bottom of the bolt.

    • Pull the wrenches apart to loosen the bolt.

    • Repeat this procedure for the remaining three bolts.

    Kommentar hinzufügen

    • Remove the four nuts and bolts securing the pump riser plate, and store them in a sanitary container such as a bucket.

    Kommentar hinzufügen

    • Rotate the pump plate 45 degrees. This will allow for a better grasp when lifting the plate.

    Kommentar hinzufügen

    • Securely lift the T-handle several inches.

    • While 2 people support the T-handle, remove the pump rod clamp.

    • Lower the T-handle gently until the pump rod is supporting itself.

    Kommentar hinzufügen

    • This particular pump is using a tripod with a block and tackle to lift the riser main. C-wrenches may also be used to lift the riser main.

    • Securely clamp and tighten the pipe elevator to the riser main below the spout exit.

    Kommentar hinzufügen

    • Being careful not to let the rope slip, use the block and tackle to lift the riser main until the pipe elevator reaches the block and tackle.

    Kommentar hinzufügen

    • Once the riser main has reached the block and tackle, tighten the base clamp against the riser main.

    Kommentar hinzufügen

    • Secure the base clamp to the frame base using a bolt.

    • One bolt is typically sufficient to keep the base clamp in place, but you can add another bolt if you wish to further secure it.

    Kommentar hinzufügen

    • While supporting the top portion of the pipe, carefully move the elevator clamp off of the pipe.

    • Lower the elevator clamp while providing tension towards the ground to prevent the ropes from tangling in the block and tackle.

    Kommentar hinzufügen

    • Attach and tighten the elevator clamp to the riser main as close to the bottom as possible.

    Kommentar hinzufügen

    • Once the elevator clamp is tight, provide tension on the rope.

    • While keeping tension on the rope to support the riser, loosen the base clamp.

    Kommentar hinzufügen

    • Use the rope to pull the riser main up as far as comfortable.

    • Be sure to keep the rope within the confines of the tripod to prevent the tripod from pulling over.

    • Watch the top of the tripod to align the riser main in the support slot.

    Kommentar hinzufügen

    • Remove the clamp from the riser main, and repeat steps 23-25 until first joint is exposed.

    Kommentar hinzufügen

    • Once the first joint is exposed, tighten the base clamp below the joint.

    Kommentar hinzufügen

    • Remove the elevator clamp from the riser main, and secure it to the tripod to keep it out of the way.

    Kommentar hinzufügen

    • Keep the pipe wrench a few inches above the joint in this step.

    • Using a pipe wrench, unscrew the first section of the riser main from the connection.

    Kommentar hinzufügen

    • Secure a splash guard over the joint to prevent water from spraying out of the connection when separated.

    • Using the pipe wrench, loosen the riser main until water begins to spray into the splash guard.

    • Do not loosen it any further until the water has stopped spraying.

    Kommentar hinzufügen

    • Remove the splash guard, and finish loosening the riser main.

    • Remove the first section of the riser main by lifting it straight up, while supporting the top of the section and keeping the pipe within the support slot on the top of the tripod.

    Kommentar hinzufügen

    • Attach and tighten the rod clamp a few inches below the first pump rod connection.

    Kommentar hinzufügen

    • Using two crescent wrenches, unscrew the pump rod from the remaining portion.

    • When the joint is separated, carefully lower the riser main to the ground.

    Kommentar hinzufügen

    • Carefully lower the riser main, horizontally, and place it in a sanitary place, preferably resting above the ground, to prevent contamination.

    Kommentar hinzufügen

    • Remove the T-handle from the separated pump rod.

    • Attach the T-handle to the remaining pump rod.

    • Remove the rod clamp and repeat steps 29-35 until the riser main is completely removed, or until the broken section is reached.
