a)Assemble the casing upper half over the lower half. Take care to ensure the renewable rings and diaphragm plate are correctly located in the upper half bores and that dowel holes pick up the locating dowels in the lower half.

b)Tap horizontal flange over locating dowels to accurately position the top half casing and torque up all horizontal flange bolts.

c)Check for free rotation.

d)Using a sharp flexible-bladed knife, cut off the exposed casing gasket in the stuffing box area flush with the stuffing box face.

e)If mechanical seals are fitted apply a small amount of silicon rubber sealant along the horizontal joint line on the stuffing box face and fit seal cover complete with gasket or O-ring. Take care not to damage O-ring, if fitted, and locate cover squarely on stuffing box face.

f)Torque up seal cover bolts and check shaft/sleeve does not rub on seal cover or stationary seal seat bore. Ensure any spare holes in mechanical seal cover, particularly on cartridge seals, have sealing plugs fitted.

g)If gland packing is fitted pack the gland, ensuring that the cut ends in each ring are staggered by 120 degrees. The glands are packed as shown on the relevant drawings in Sections 8.1 to 8.3. Finger tighten the gland nuts.

h)Check coupling alignment, fit coupling drive element(s) and fit guards.

i)Pipe up any external auxiliary connections.
