Plumbing Assembly/

Pump may be bolted to skid base during reassembly.

Using antiseizing tape or sealing compound, wrap or coat the external

Centrifugal pump (8)

Pipe nipple (9)

threads of pipe nipple (9), lower manifold (11), upper manifold (13), pipe

Pipe union (10)

bushing (15), pipe nipple (16), and pipe nipple (18).

Lower manifold (11)

Position centrifugal pump (8) upright on a flat surface. Screw together

Offset valve (12)

pipe nipple (9), pipe union (10), lower manifold (11), offset valve (12), and

Upper manifold (13)

upper manifold (13). Then screw into centrifugal pump (8) and hold in

place while each part is tightened, starting from its lowest point, with a

wrench. Do not tighten two parts of pipe union (10). The outlet in lower

manifold (11) must be alined with centrifugal pump (8). Firmly holding

lower manifold (11), tighten offset valve (12) until the handle stem is

opposite the port on lower manifold (11). While holding offset valve (12),

tighten upper manifold (13) until it is tight and alines with the shaft in

centrifugal pump (8).

Regulating valve (14)

Screw regulating valve (14) onto upper manifold (13) and screw pipe

Pipe bushing (15)

bushing (15) into regulating valve (14). Tighten pipe bushing (15) and

regulating valve (14) until the stem is pointing in the same direction as

offset valve (12).

Pipe nipple (16)

Screw pipe nipple (16), pipe elbow (17), and pipe nipple (18) together.

Then, as a unit, screw into pipe bushing (15). Tighten pipe nipple (18) and

Pipe elbow (17)

pipe elbow (17) until the outlet is vertical and is pointing downward.

Pipe nipple (18)

Tighten pipe nipple (18).
