Which factors may affect the life of deep well pump.

Which factors may affect the life of deep well pump.
1, deep well pump motor horsepower or motor size. Larger motors, such as 3/4 or 1 HP (horsepower or CP) motors, typically collapse a small fraction of 1/8 or 1/4 horsepower electric motors for the same application and workload.
2, deep well pump cycle. A deep well pump is known to run on the pump several times a day and will have a considerably longer life than the heavy or continuous use of the same deep well pump. The reason why an owner installs a larger or captive air bladder air tank is to extend the water draw cycle, thereby reducing the frequency of turning the deep well pump and shutting down. For details, see Deep Well Pump Duty Cycle.
3, water equipment installation quality. Can make the water supply equipment life is very different. If the installer simply pumps and routes underground, no check valves, filters, appropriate electrical wiring, etc., will greatly damage the life of deep-well pump.
4. Water deposits are the major wear factor (relative to the deep-well pump driven by the electric motor) in the deep well pump assembly itself.
