2016-12-2 · In a positive-displacement (PD) pump, a discrete amount of fluid is trapped, forced through the pump, and discharged. A gear pump is an example of a PD pump (Figure 2). This pumping principle produces a pulsating flow, rather than a smooth flow. Its output flow tends to vary little with respect to the pressure at the pump outlet, because the moving

An important design consideration for workholding applications is to use the vacuum pump only to achieve the vacuum level required. Once the workpiece is in contact with the vacuum cup and the required vacuum achieved, de-energizing a normally closed valve will hold the vacuum indefinitely - provided no leakage occurs.
