  • Selecting the Right Pump for the Job
    . The pump's diaphragm has also seen many changes over the years. Traditionally, the diaphragm consists of a flat elastomeric sheet clamped in place around the edge. It is fastened to the oscillating connecting rod at the center using a screw and metal disk. Material is machined from the head to provide room

    especially above about 1,500 rpm. Screw pumps, on the other hand, almost completely over-come the oil-encapsulation problem by moving oil along a parallel path, instead of one perpendicular to the axes as the pump rotates. Screw pumps typically run silently with low pulsations, for low to medium
