The "ejector" as they are known in the south are also known as the "jet head" or simply the "jet" up north. Not all have the pipe-in-pipe design, that was done on small diameter wells, larger diameter wells (5"+) normally use a pair of pipes side by side, a larger one for the suction and a smaller one for the jet.
If you're replacing the pump, I very strongly suggest you pull the jet up too. Check all the pipe for leaks. Disassemble the jet and if it's got replacable seats/valves, just go ahead and replace them. If the jet or the pipes look questionable, now is the time to replace them.
Another thing that will save wear & tear on the pump is adding an additional check valve on the suction line close to the pump itself. The pump normally has a built-in check-v but most do not seal as well as a good quality ball/piston-seat type check valve (using one size larger valve than the nominal pipe size reduces flow friction losses.
I'd also suggest checking the prices too because it may be cheaper in the long run to install a submersible pump.
