ABSTRACT:
An improvement for deep water well pumping equipment which comprises a suction tube extending down from the intake port of the pump equipment to the bottom of the well. The suction tube has a series of apertures spaced along and around its surface. Each aperture can be formed as a water guiding admissor to direct the flow toward the intake port. The spacing of the admissors is calculated to provide a substantially uniform flow of water through the admissors into the suction tube. This uniform flow reduces the turbulences that normally develop near the intake port and thereby reduces the amount of silt entering the pumping apparatus. This uniform flow also draws water from the surrounding aquiferous layer in a more lateral fashion, thereby reducing the depth of the dynamic pumping level and increasing pump efficiency.
