As these pumps are submerged all the time, most of us tend to overlook the maintenace of it
Most failures are detected only when the pump stops pumping and by then , maintenace cost will be high as the seal leaked and electric motor got burnt , bearings damaged and motor stator
could also be damaged
It is highly recommended that preventive maintenance be carried out seriously . mechanical seals and bearings replaced as schedule.This will save pump from unnecessary damages
While Submersible pumps are easy to istalled and save space , it is sometime to costly to
maintain compared to end suction or self priming pumps
Verticle sump pump will be another option and very little maintenance are needed
However ,the pump is usually costly
