Today we got a call from Hamilton Hill and another from Dianella. Both wanted to know whether could we replace their old centrifugal pump in their well style bore with a modern submersible pump. It is a common question from all over Perth in older suburbs where centrifugal pumps or jet pumps were common in the old well style bores and now need replacing. Answer….sometimes we can substitute with a submersible pump installation but ONLY if the casing at the bottom of the well liner(s) that goes into the ground ( some people may refer to this as a spear ) is of 100mm ( 4 inch ) or more. Typically that would be when it has freestanding suction ( where the pipe from the existing centrifugal pump suction side goes in to the ground inside a larger outside pipe) or where the bore has been redrilled within the last 15 or so years. We can also substitute a centrifugal or jet pump with a submersible in the (rarer) older wells with open water in the bottom.
