A system for separating fluids of differing densities includes a pair of pum ps interconnected to and driven by a motor positioned therebetween. The pumps each have intake ends, distal second ends, and a pump intake proximal the intake end. The pumps, the motor, and a production tubing form a production string. A shroud is sealably connected to the production string at one end of the shroud at a position intermediate the motor and the pump intake of one of the pumps. The shroud surrounds the pump and extends at least partially over the pump. The shroud forms a fluid communication passageway between the pump and the shroud and an orifice at t he end of the shroud opposite the sealed end to form an effective pump intake. A second shroud similar to the first shroud surrounds the other, second pump and is sealably attached to the production string intermediate the motor and the second pump . The effective pump intakes formed by the shrouds are at least sixty feet from on e another.
