Abstract
A flow control device to be coupled to the intake of a pump including a base, an outlet plate having an outlet formed therein generally opposing the base, and a plurality of annular baffles carried between the base and the outlet plate. The annular baffles are spaced apart to define a plurality of inlets. Each of the plurality of annular baffles has an inner diameter, the inner diameters defining an interior void.
Claims10
A flow control device for controlling the flow of a fluid into the intake of a pump, comprising:
- a housing defining an interior void and having a base plate, an outlet plate and a plurality of annular baffles carried between the base and the outlet plate, each of the plurality of annular baffles has an inner diameter, the inner diameters defining the interior void;
- an outlet defined by the outlet plate and couplable to an intake of a pump;
- a plurality of inlets defined by the plurality of annular baffles of the housing and encircling the interior void, the plurality of inlets being disposed at an angle to the outlet;
- a buffer member centrally positioned within the void and having a surface substantially opposing the plurality of inlets for facilitating redirection of fluid entering the inlets to the outlet, the buffer member having a cone shape with an apex directed toward the outlet;
- and
- the inner diameters of the annular baffles are each configured to maintain a substantially equal distance from the cone.
