Monoblock Surface Solar Pumps are good for applications with shallow wells, ponds, streams or storage tanks. They are best if the water supply is 20 feet or less from the surface. However, once they have lifted that relatively small amount, surface solar Shallow open well pumping with suction lift.
Open well submersible pumps are used when the applications will face a frequent change in water levels. It can be dropped and fitted to the bottom of an open well or sump pump. the pump is placed horizontal and can be used for a dept upto 30 ft.
Deep well submersible pumps, when water source is located very deep underground, then it is necessary to use a deep bore well for water extraction. When aquifers are suitable for water extraction, a suitable location for the pump installation is chosen and a small diameter deep bore well is sunk into the ground and lined with tubes. Pumps can cater dept of the borehole from 10ft to 1200ft.
