When it comes to choosing submersible pumps, it is important to pay attention to what workers in mining operations consider important aspects. Mostly, it will be durability (less time and effort spent on pumps that need service) and portability (inevitable mobility of pumps to clear blast areas). Often, operators will prefer the easiest plug-and-pump type of submersibles that provide incorporated start and motor protection. These are increasingly available on most higher-power pumps. Technological advances in electronics are also making built-in soft starters increasingly common, thus providing lower start currents and related start jerks when repeatedly starting electric submersible pumps. Lower stress on mechanical structures around the pump translates into longer service life.
