Surface Bore Pump
SURFACE BORE PUMPS are also called CONVERTIBLE JET PUMPS. They use a venturi system with 2 pipes. Being ‘Above Ground Bore Pumps’ they need to be primed at all times. How they work is by pushing water down the hole through one pipe, through the venturi which forces the water up the other pipe and into the pump. These convertible jet pumps can handle a max depth of 50m and the flow slows the deeper the depth it draws from.
