ABSTRACT:
A support head for sealing the top of a cylindrical well casing and also for supporting a vertical well pipe and pump in suspended relation in a well. The head has a top surface and also a downwardly facing surface to engage the top edge of the well casing in a sealing support. A vertical opening is provided in the head to slidably receive the well pipe, and a seal is provided around the vertical opening so as to engage the vertical well pipe and be sealed by a fitting on the pipe by the weight of the suspended well pipe and pump. The seal between the head and the well pipe comprises a compressible sealing gasket in an annular recess also operable in sealing relation by the weight of the suspended pipe and pump.
