The pump casing was hand ground along the crack. Two (2) holes were drilled to stop the crack propagation. The casing was slightly split to allow insertion of Belzona 1212, then clamped shut. The outside crack was filled with Belzona 1212, Six (6) steel tabs were bonded with Belzona 1212 to wrap the crack along its length and add strength to the repair. The pump was painted to complete the repair.
