Liquid Jet Eductors - The "Pumps" with No Moving Parts

introduced into the pump system. Generally, this volume is much lower than in most eductor systems. Priming eductors are designed mainly as priming devices for mechanical pumps. These water jet exhausters are used to remove air rather than water. Liquid jets are not well suited for pumping noncondensables; therefore, capacities are low.

Centrifugal Pumps: Fight Flow Recirculation | Chemical .

Figure 2 shows a schematic of net flow in a pump at its best efficiency point (BEP) and at a low flow condition (0.25 of the BEP). At low rates, the flow passages in the pump are simply too big. Nevertheless, they must be filled with liquid. Flow recirculation results.
