Abstract
A pump inlet screen for a submersible pump adapted to be inserted into a well bore. The screen includes an inner support sleeve having openings therethrough and an outer mesh screen member that overlies the out surface of the inner support sleeve. A polymer coated reinforcing ring is secured to one end of the screen and includes spaced, radially-extending threaded openings for receiving set screws to permit securement of the inlet screen to the outer surface of a cylindrical housing. The opposite end of the inlet screen from the reinforcing ring includes a sealing ring having an inwardly-extending, sloping lip seal to engage the outer surface of a cylindrical housing.
Claims16
A pump inlet screen comprising:
- a) an inner annular support sleeve having a plurality of openings to allow liquid to pass radially therethrough;
- b) an outer screen member overlying an outer surface of the support sleeve, the outer screen having a plurality of openings having an opening size smaller than the openings in the support sleeve;
- c) a rigid reinforcing ring positioned at a first longitudinal end of the inlet screen, the reinforcing ring including securement means for securing the inlet screen in a desired position on a tubular pump body having a suction opening and so that the inlet screen overlies the suction opening to limit the sizes of particles that can pass therethrough;
- and
- d) a flexible sealing ring positioned at a second, opposite longitudinal end of the inlet screen for blocking flow between the second end of the inlet screen and the tubular body member.
