A generally uniform diameter elongated barrel unit secured to the top of a well casing which provides a seat for a spool unit having spaced plates defining a flow directling central space to a lateral distributing pipe. The plates have peripheral sealing means engaging sealing rings of stainless steel material on the inside of the barrel unit. The apparatus may be arranged for use with either a turbine drive type pump having a ground level motor or a submersible pump. The spool unit is inserted into and may be withdrawn from the barrel unit by axial movement. A heavy flange is welded to the top of the barrel unit to provide a heavy duty work platform and motor mount or support for a cover.
