Motor lubrication checks
• For grease-filled bearings, make sure that grease is not all over the inside of the motor
and in the bottom of the motor. This could be a sign of overfilling. Refer to the
lubrication instructions from the motor manufacturer.
Close-coupled pumps
• For a horizontal pump, verify that the mechanical seal is not leaking between the
pump and the motor.
Sound and visual checks of the whole station
• Listen for any odd sounds that rub or grind, electrical arcing, and check for anything
that is binding or unusual. These conditions can indicate a serious problem.
Note that there is going to be some harmonic vibration with the pumps and motor.
Listen for excessive vibration or noise as this requires immediate service. Do not
operate the pump if there is excessive vibration.
• Confirm that the building cooling and ventilation systems are operating and clear of
all obstructions. The maximum operating range for equipment is 104°F (40°C).
• Verify that water, grease, oil, and hardware are not leaking or loose on the pump
station.
Station skid
• Visually inspect for leaks in the station piping, valves, and other components.
• Visually inspect the piping and skid for any stress cracks in the welds.
• Visually inspect the station for loose or damaged paint or areas of rust.
