Submersible pumps can be applied to many distinct applications,
from pumping large solids or grinding solids to smaller sizes, to
transferring waste water at large flow rates or high pressures, to
simply pumping up water off the floor or the bottom of a tank;
depending upon submersible pump design. Some of the more common
submersible pumps designed for specific applications include water
submersible pumps, sewage submersible pumps, 12 volt submersible
pumps, sand submersible pumps, irrigation submersible pumps, and
solar submersible pumps. Solar submersible pumps, while not
specific to an application, are best used for slow and steady water
transference into a holding tank, but may also be used for direct
pressurization applications.... that's my answer... shreya
