3 Unit Installation
• Position the unit as shown.
• Install the unit according to the liquid flow of the system.
• The arrows on the pump body indicate the flow and the rotation direction.
• The standard rotation direction is clockwise (looking at the fan cover).
• Always install a backflow-prevention device on the suction side.
• Always install the pressure sensor on the delivery side, after the check valve.
4 Check Rotation
1. Unlock power to the driver.
2. Make sure that everyone is clear, and then jog the driver long enough to determine that the direction of rotation corresponds
to the arrow on the pump. Pump rotation is clockwise when viewed from the back of the motor. An arrow is provided to show
rotational direction.
3. Lock out power to the driver.
5 Piping Requirements
Check that a section of straight pipe, with a length that is a minimum of five times
its diameter, is installed between the suction side of the pump and the first elbow,
or that a B&G Suction Diffuser is installed.
Check that you have a foot valve of equal or greater area than the pump suction
piping when you use in an open system with a suction lift.
Check that the suction and discharge pipes are supported independently by use of
pipe hangers near the pump.
Check that a B&G Triple Duty® valve is installed in the discharge line.
Check that there is a strong, rigid support for the suction and discharge lines. Check that the pipeline has isolation valves around the pump and has a drain valve
in the suction pipe.
For pumps with flanges, check that the bolt holes in the pump flanges match the
bolt holes in the pipe flanges.
Use PTFE tape sealer or a high quality thread sealant when you install the suction
and discharge connections to a threaded pump housing.
Check that the suction or discharge lines are not forced into position. 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.
Check that fittings for absorbing expansion are installed in the system when con‐
siderable temperature changes are expected.
Check that new flange gaskets are installed between the flanges of the pump body
suction and discharge pipes. Make sure that these gaskets are clean and grease-
free.
