Openwell submersible pumps are designed for underwater application, so there is no need of priming and foot valve as compared to monoblock surface pumps. So, openwell submersible pumps are replacing monoblock surface pumps at number of places because of some of the inherit advantage such as–

• 1. Cooling is much better & hence longer life. .
• 2. Noiseless operation.
• 3. Carbon VS Stainless steel thrust bearing pad smoother operation.
• 4. The openwell submersible pump can be place at the bottom of the well, this arrangement does not require suction pipe.
• 5. Easy installation and maintenance.
