Bell & Gossett P82893D Series 60 In-Line Centrifugal Pumps - Manual (Page 15)

Check Explanation/comment Checked
Check that the pipeline has isolation valves around
the pump and has a drain valve in the suction pipe.
—
Use PTFE tape sealer or a high quality thread sealant
when you install the suction and discharge
connections to a threaded pump housing.
—
On an open system, check that the end of the suction
pipe is at least 3 ft. below the surface of the water in
the suction well.
This prevents air from being drawn into the
pump. Avoid air pockets in the suction line and
make sure that each section of the suction pipe
is air tight.
Check that new flange gaskets are installed between
the flanges of the pump body end suction and
discharge pipes. Make sure that these gaskets are
clean and grease-free.
Suitable fasteners for this connection are
supplied in the Xylem fastener pack. Apply a
torque of 8 to 11 ft. lbs (11 to 15 Nm) to each of
the flange bolts. Both the suction and
discharge flanges must be torqued to the same
level.
Pump orientation
You can install this pump to discharge up, down, left, or right. However, make sure that
you install the pump according to these pump orientation guidelines:
• Reposition the pump body by removing the body bolts and rotating the body around
the bearing assembly.
• Only install the pump with the motor shaft horizontal.
• The bearing assembly vent slots or coupler access window must always face up.
• Do not reposition the motor on the bearing assembly.
• The arrow on the pump body must point in the direction of the flow.
