expel any leftover fluid that might freeze and damage rotating parts in the
pump.
b. Drain and rinse the pump with clean water when it has been sitting for longer
than several hours. Also, drain and rinse the pump with clean water when
there have been a significant quantity of solids in the fluid being pumped.
c. Insert a strong wire or rod into the drain port, and briskly stir the fluid while it
is draining. This will stop bulky solids from blocking the drain port causing
liquid to remain in the pump. Flush the pump with clean water to remove
leftover solids.
E. CHECKING THE BEARING TEMPERATURE
Friction generated heat normally causes bearings to run at higher than normal
temperatures.
Normal temperatures for bearings range between 160º F (71º C) and 180º F (82º
C).
Avoid testing bearing temperatures by hand because the measurement is
inaccurate. Instead, determine the temperature of the bearings by touching a
contact-type thermometer to the bearing housing then document the temperature
for accurate record keeping.
Bearings are nearing the point of failure when there is a sudden rise in bearing
temperature. Check for adequate viscosity of the bearing lubricant and be sure it
is at the appropriate level as noted in Section F., LUBRICATION. Incorrect
positioning of the shaft can cause overheating of the bearings. Too much
vibration can also cause the bearings to overheat.
During initial pump start-up, the bearings may seem to operate at higher than
normal temperatures, however, continuing pump operation should reduce the
temperatures to normal operating range.
