,Mechanical seal failure A failure that can occur due to overheating,
excessive vibration, and low flow rates.
Centrifugal pump A device that moves liquids by transferring
kinetic energy.
Air blower A device used to supply oxygen to aerobic
processes in wastewater treatment.
Motor maintenance checks Routine checks that include lubrication of
bearings, voltage and current levels, and
alignment with the drive shaft.
Corrosion prevention in Typically achieved using stainless steel due
mechanical components to its resistance to corrosion.
, Pump not priming Checking the pump's discharge valve to
troubleshooting ensure it's fully open.
Cleaning a clogged pump Recommended to remove and manually
impeller clean the impeller with a brush.
Safety precautions with Ensuring the motor is properly grounded to
electrical motors prevent electrical shock.
