There is a saying, “Always pick the right tool for the right job.” Same is the case for water pumps. So far there are two main types of pump in the market: Surface Pumps and Submersible Pumps. Our customers have always been asking, what’s the difference between the two? Here is the clarification:
Surface pumps sucks the water from the well to the pump from a maximum depth of 24′ below surface. These pumps will only generate around 50 psi depending on how low the water level is at the time.
Submersible are generally vertical multi-staged centrifugal pumps where the pump is below the free surface of the fluid to be pumped. It pushes the water to the surface instead of sucking it. A submersible pump never needs priming and delivers more volume and better pressure!
So basically if you are targeting water with low depth, surface pump would be much preferable, on the other hand, if you require something installed much deeper, submersible pump would prove to be more useful than surface pump.
