SECTION III
OPERATION
III-A START-UP CHECK LIST
(a) Checking shaft rotation
1. With power, off and locked out, remove spacer between coupling hubs.
2. Restore power, and momentarily energize motor to determine rotation. Motor shaft must rotate in
direction of arrow on the pump bearing frame.
3. Shut off power and lock out.
4. Check impeller clearance. Pumps assembled at the factory are set at .015-inch clearance. Do not rely on
factory setting which could be affected by piping connections, or if high temperature liquids are to be
pumped, the impeller setting must be corrected. See appendix for adjustment procedure.
5. Reinstall coupling spacer. Make sure coupling hubs are secured to the shafts. Lubricate coupling as
required per manufacturer's instructions.
RECHECK ALIGNMENT .
6. Install coupling guard.
(b)
Bearing Lubrication
Oil Lubrication: PUMPS ARE NOT SHIPPED FROM THE FACTORY WITH OIL.
1. Remove item 113A (oil fill plug) and fill frame with oil to the center of the sight glass. A high quality
turbine oil with rust and oxidation inhibitors should be used. See Appendix for oil recommendations and
instructions for filling frame with oil when Trico oilers are installed.
Pure Oil Mist Lubrication: The power frames have, as standard, drilled and tapped connections for oil mist
systems. The connections are located on the top of the bearing frame. Follow instructions from the
manufacturer of the oil mist generator system. If you are already using flood oil lubrication, instructions for
converting to oil mist are in the Appendix.
Grease Lubrication: Pumps shipped from factory contain some grease but it is not sufficient for placing
the pump into continuous service. Refer to instructions in the appendix.
Greased for Life Bearings: These bearings are greased and permanently sealed by the bearing manufacturer.
See appendix for recommended lubrication schedules.
(c) Shaft Sealing - Refer to section Il-Q page 20.
Never allow pump to run dry, or operate pump without liquid in the seal chamber. Seal faces must always be
lubricated. Operating a pump without liquid in the casing or seal chamber, even for a few moments, can cause
seal failure, pump damage and or personal injury.
