Three types of submersible pumps
Submersible pumps fall into three categories:
Each functions slightly differently. Manual pumps can be switched on and off at the power point by the user. Automatic pumps, which are the traditional style, turn on automatically when the water rises to an appropriate level. This is achieved via a floating switch, attached to a swinging arm Vertical rigid automatic pumps also switch on in response to rising water levels, but can function in shallower water than that demanded by a traditional automatic pump. Moreover, being comprised of a cylindrical tube containing magnets, rigid automatic pumps do not require external moving parts. They never become "stuck" and are known for their reliability.
Materials and manufacturing
When selecting a submersible pump, one of the crucial issues to consider is quality of materials and workmanship. Durable, resilient pumps are usually made of high quality stainless steel, cast iron or hard plastic. On that note, buying from a trustworthy company is a must.
