Flowserve Vertical Immersion Sump Pump 1E3x2SP-82

5.8.7 Normal Vibration Levels, Alarm and Trip

Record the current vibration velocity (unfiltered) in mm/s (r.m.s.)

Is the vibration velocity within normal range (5.6 mm/s r.m.s.)?

Is the vibration velocity within alarm range (7.0 mm/s r.m.s.)?

Is the vibration velocity within shutdown range (11.3 mm/s r.m.s.)?

Describe any observed changes in vibration velocity outside the preferred flow region.

Observe pump for any abnormal noise or vibration.

Check for any change in pump noise or vibration.

5.1 Pre-commissioning procedure

Ensure all pre-startup checks are completed

Rotate the shaft by hand to ensure all rotating parts move freely and there are no foreign objects in the pump casing

Ensure the pump is primed and the sump liquid level covers the casing and adapter

Start and regulate all flush lines

Start the driver (typically, the electric motor)

Slowly open the discharge valve until the desired flow is reached

Check for issues after starting the pump

Ensure the gland nuts [6580.8] are evenly finger tight.

Tighten the gland nuts an additional ¼ turn.

Is there a slight amount of leakage through the gland [4120.1]?

Ensure packing glands are not tightened to the point where leakage is stopped.

Is the gland packing adjusted to give visible leakage?

Is the gland follower in concentric alignment?

Ensure there is no excessive temperature of the packing or follower.

Verify packing sizes for each group

Install packing rings one at a time, ensuring each is pushed well into place

Enter the number of packing rings installed before the seal cage

Install the seal cage after the initial packing rings

Continue installing packing rings until the box is filled

Are the joints of succeeding rings staggered?

Does the taped hole in the stuffing box line up with the seal cage when packing is compressed?

Draw up the nuts on the gland evenly finger tight after the last ring of packing is in place

Verify bearing temperature is within the specified range

Select the lubrication group based on re-lubrication amounts

Lubricate the external duplex angular contact thrust bearing through the grease fitting [3853.2]

Verify the grease used is recommended or compatible

Ensure not to overfill the motor or pump thrust bearings with grease
