8 They operate by the con-version of pressure energy into velocity in suitable nozzles. They are pumps without moving parts .The basic principle of jet pumps consists in the liquid or gas jet being emitted by a noz-zle at high speed entraining and accelerating the surrounding liquid, gas or solid matter. The result of this action is a mixture of the driving and entrained (sucked) fluids, the velocity of which is reduced and the pres-sure increased in a second nozzle. The practical application of this principle requires a simple apparatus which essential-ly consists of only 3 main parts (figure 1): motive nozzle (1) diffuser (2) head (3)The flow channel of the diffuser consists of a part converging in the direction of the flow (the inlet cone), a cylindrical piece (the throat) and a diverging part (the out-let cone).

9 The pressures at the connections and the corresponding mass flows determine the functional effect of a jet pump. A jet pump is provided with at least 3 con-nections (figure 1): motive medium inlet connection (A) suction manifold (B) pressure manifold (C)The pressures prevailing there are as follows (figure 2):p1 pressure upstream of the motive nozzle = motive medium pressurep0 pressure at the suction manifold = suction pressurep pressure at the outlet manifold = discharge pressureThe mass flows 1, 0 and for the enter-ing and exiting fluids are measured in kg/h. For this purpose, the following equation shall apply: 1 + 0 =.

10 For the relationship between the various pressures, no simple rule can be applied. The internal processes in jet pumps are complex and only in a limited way accessible by cal-culation. FIG. 1 FIG. 2 DESIGNATIONS OF JET PUMPSThe terms of jet pumps (ejectors) are defined in DIN 24290. According to DIN 24290, jet pumps are named according to the motive side and to the suction side.
